Comfort Tech's Owner Satisfaction

Each of us need to survey the customer reviews before we invest in a pricy product. That said, it's not always easy for shoppers to come up with takeaways after looking at many different mattress sites. In our investigation of reviews and sentiment from customers, we discovered that sleepers give these mattresses above average scores. However, some couldn't get as comfortable. Research more below to see if one of these mattresses will work for you.


Comfort Tech's Supportiveness

Most customers describe these mattresses as having above average supportiveness, which is what you want when you've been sleeping on a sagging mattress from the past few months. That said, some reviewers have mentioned support issues in reference to their bodies, so take a look at some of the other reports from customers to make sure your choice is right for your body.

Edge Support
Edge support is how much resistance there is along the sides of the mattress. These mattresses over good support overall, but some that are heavier may experience some softness.


Comfort Tech's Durability

Finding a mattress that has comfort that lasts can save you lots of money. Unfortunately, nowadays everything from what you wear to where you sleep degrades faster. These mattresses, specifically, have mixed ratings when it comes to longevity. These mattresses may last years for you, but others have reported not being as lucky. Make sure that your mattress choice works well with your body before purchasing.

Novaform's Owner Satisfaction

Using customer reviews as a guide can be great for discerning shoppers. Unfortunately, customers don't always have good things to say about these mattresses. Some feel cozy and comfortable, but others don't feel that way. If you are contemplating ordering, see below for more specifics that may be helpful.


Novaform's Supportiveness

Some reviewers feel good amounts of support in these mattresses, but some others have complained about loss of support. For those with achy backs that need spine alignment, read the reviews to make sure the mattress works with your body.

Edge Support
The customers have mixed thoughts about edge support on these mattresses. Some folks have reported good amounts of comfort throughout the mattress, but others had issues with lumpiness.


Novaform's Durability

Finding a long lasting mattress is great, but it's not always that easy. Unfortunately, customers don't tend to rate these mattresses well in terms of durability. That said, some mattresses may last a significant time without problems, while other mattresses may break down faster. If you are a bigger person, take some time reading more before buying.

The price is right!
After being deeply disappointed in an overpriced Beautyrest mattress we thought we would try a memory foam as these seem to be the highest rated and with $100. off the price, it was worth a try. It was (surprisingly) firm to us, a little too firm. The next night I put a 3 inch memory foam topper ( already had it) on and it is perfect for us now. Our previous mattress had sagged after a few months and the manufacturer replaced it as guaranteed, but only with the same exact mattress! What is the use of that?? At least if this happens I have Costco's return policy and it was only $400 bucks not $2000. So far so good. I will follow up in two months.

Exactly what we were looking for, comfort like no other twin mattress.
We bought queen size Comfort Tech 10'' Serene Performance Foam mattress about eight months ago. It is very comfortable and feels almost soft to the touch but once you lay down on it it cradles your body without sinking into a hole. The Medium density description fits the bill. My husband is 6' and weighs 170 lb and I am 5'4'' and weigh 120 lb. Also I don't sweat at night which I used to on our previous foam mattress. The only small minus is that the edges are softer than on our older mattress which might be an issue for some people.

Good Sleep
I bought this mattress for based on 2 reasons, price and reviews. Having never slept on a foam mattress, I was skeptical about this purchase. I decided that based on the price ($350 on sale) it was worth a try. After the first night I knew I had a winner. Two months of use and I am still waking up feeling rested. As a side sleeper, my arm and hips no longer ache in the morning. As a tummy sleeper, my wife's back doesn't ache in the morning either. We couldn't be happier. So glad that we didn't spend hundreds more for a traditional spring bed.

Love this mattress!
We bought this mattress several months ago, after researching mattresses for far too long! Desperate for a new mattress, and overwhelmed by the information and options available, we decided that this one was so inexpensive, it wouldn't be a risk to just buy it. We were unhappy with the uneven wear of traditional springs. Nor did we care for the 'stuck' feeling of memory foam. This mattress is a joy to sleep on! It is supportive and cushioning. I disagree with the review that says it holds the impression of your body. Ours does not do that at all. It is absolutely nothing like the memory foam mattresses we slept on in the past.

My new favorite mattress!
The great reviews for this mattress gave me the courage to order it sight unseen and I'm so happy I did/ Shipping took a little longer than expected but customer service was great. I don't know if I would have bought this if I'd just sat down on it in a store as it feels really firm at first and my last mattress was a pillowtop. With that being said, I love this. I can toss and turn in bed and not wake up my husband. I don't wake up with any aches or kinks in my body. Normal sheet sets fit it perfectly. When it was hot, I didn't feel like the mattress was guarding any of our body heat. I will definitely be replacing future mattresses in our house with this brand and buying one for the travel trailer! Warning: Definitely do not open the plastic wrap until you have the mattress in the room where you want it. That sucker just swells right up and it's harder to move because it doesn't have the traditional binding/edges like other mattresses.

feels just right
I was skeptical because of the price but we loved it from the first night! More comfortable than our Temper-Pedic

Great buy for the price
Bought this mattress based on my friend's recommendation and the reviews here. It came in a small box and came to full size once opened. It had a chemical smell for the first 2-3 days but disappeared eventually. It is medium as listed, not firm. It sinks when you sit on it, but when you sleep you won't sink and feel relaxed. When you press it, it reacts lot quicker than a memory foam mattress, so you change positions easily. The mattress is great for side, back or stomach sleepers. We have been using it since 2 weeks. We are loving it and are having sound sleep every night. It doesn't feel hot when I sleep on it. We tried many mattress at stores and were skeptical to buy online. I thought of giving a try before buying at store, because of Costco's great return policy, but I wanna keep it since it's great and cheaper. I recommend this product. It's a genuine review and I was not paid to write this.

We have had this mattress
We have had this mattress for a little over a year and both my side and my husbands side of the bed have sunken in. This has caused the middle of the mattress to be higher than the sides so if you try to lay near the middle, you feel yourself rolling towards the edge of the bed. Also, though they say this mattress is Medium firmness, we would say it's slightly more on the soft side. Would not recommend this at all. I hope to be able to return this, but not sure if I can since we've had it for a year.

Great at first... 1 year 5 months later...
Bought this mattress Feb 2016, it was awesome at first. Agree with most reviews on quality of sleep but not so much on firmness. So if you sit at the edge of the mattress you will squish it all the way down. If you kneel on it, your knees will sink all the way down. But when you lay on it, weather on your back, stomach or side, the mattress will distribute your weight evenly and hugging you confortably for a great nite of sleep. It is truly amazing!!! I sleep in all 3 positions. On my old mattress if on my side, I'd wake up with aching hips and shoulders. Not on this mattress though. Instant relief very first night. It is now July 2017, and for the past 6 months I'd say, this mattress does NOT feel like it did at first. I rotated it according to instructions. But it's just not the same. According to the manufacturer description, it will feel softer as it ages. My wife and I however come to the conclusion the opposite is happening. The mattress feel as it gotten harder. It no longer conforms to our bodies giving us that even weight distribution I first described. And I am starting to pick up on pressure point when I sleep on my side. Wife and I have contacted Costco to arrange return. Haven't decided if will simply exchange for same model or get a refund and try different brand. Oh, also it claims to be cool, but it is not. We found it to be quite warm.

Great for a while..
I have had this mattress for 8 months. I would say the first 5 months it was great! However, after waking with terrible back pain, I noticed how bad it was sagging. I tried several toppers and pads and it just didn't help. I always turned the mattress (it can't be flipped) and still didn't help. Could be good for an occasional guest bed, but not for everyday sleeping. I have to start the mattress search over again...

Comfortable memory foam
If you like memory foam in general, this mattress feels soft and relieves pressure. I would rate it about a 5 on the firmness level, with 10 being the highest. So it is a little softer than some other leading brands, which was a plus for me. If you are not sure about the idea of Serene Foam vs memory foam...it definitely feels like memory foam. It leaves the classic indentation where you have just been lying. People that are used to memory foam will most likely love it, if they like a plush feel. I, however am not and didn't like feeling stuck. I used Costco's return policy with absolutely no problems. They did just what their policy stated they would do.

Comfortable
We were hesitant to buy a foam mattress. This one sleeps cool, very comfortable. Didn’t find it overly soft, it’s a medium support in my opinion. Unwraps and fills quickly. No odor.

Wonderful!
We bought this for our toddler who was moving into a twin bed. It is so, so comfortable. He loves it-along with everyone else in the house! Mattress was easy to unpackage and was ready to go in moments after expanding. Would highly recommend-such a great price! Would certainly purchase another when needed!

Mattress is okay but...
We purchased two Twin XL a couple of months ago for our adjustable twin frames. They are supposed to be medium firm but would have to disagree and lean towards soft. As of yet I have not noticed any defects and I will have to take a closer look and report back. The mattress is too soft so not sure what I will do.

Good buy
Very comfortable. Great price

comfort plus
I bought this mattress for my 15 year old grandson. He absolutely loves this thing!! He said he is sleeping so much better, and he wanted us to come over and try it ourselves. He was right. It is extremely comfortable.

Perfect fit!
My husband and I bought this mattress 1 momyhsgo after sleeping on the same one in a spare bedroom at my friends house. It’s the perfect mix of firm with some give. First time my husband and I have been able to agree on a mattress!

Great value
I bought the Serene Medium foam mattress a few months ago, after I moved into a new house, for the guest room. I had originally bought an I-comfort mattress and box springs for my master bedroom at a furniture store and could not get a full night sleep on it. This mattress cost one third of what I paid for the one in my room and it is just so much more comfortable that I have moved it into my room and the guests will have to make do with the other one. The Comfort Tech was advertised as not too firm and not too soft. In a few words, it is Just Right.

Feels firm, yet comfortable.
We bought this for my son. It is firmly supportive and he loves it. I was thinking about purchasing the firm mattress for my husband and me, but the medium is firm enough. I have sat on it and it doesn't sink, or leave a lasting imprint. My injured tailbone wasn't bothered. We highly recommend this mattress.

Good mattress
Very happy with the mattress, process and delivery.

Great rest!
I bought this abut a month ago for my son, he loves it!

Firm but not hard
I love this mattress. It's firm but not hard or uncomfortable.

We received our comfort tech
We received our comfort tech on December 8th, and have had the best nights sleep ever. The quality and comfort of this mattress goes without saying. We are full time RVers and travel a lot so a good night sleep is extremely important. All we say is this is the best mattress we have ever owned.

Bought it for my son
Bought it for my son. So far he is happy with it. He said it keeps him cool around his body. So, he sleeps well.

Very Comfortable
When I first opened the mattress, it comes flat with the air squeezed out, it seemed way too soft. One day later it was perfect so don't be upset at first. Costco had this on sale which made it even a better deal.

My son loves his new mattress.
Mattress unfolded nicely, little initial odor. He slept on it right away and is quite happy to have upgraded.

Amazing bed
We bought our king and my daughter loved it so much she bought the queen and loves it!

Great quality
I had really good sleeps on this mattress.


Purchased September 2018. Delivered in about 1 week. Unpacked left open to air out Then put in bed . It’s great my son loves it !

Comfortable
Very good quality

Feeling comfortabl to sleep, Firm foam and sleep w
Bought this 2 weeks ago for my youngest son He loved it because he used to have a back pain of the old mattress, Firm foam made him fall asleep easily. Thanks God we got it

Good choice between, not to soft and not to hard
Provides firm support, especially at the edges, while supporting my back. This mattress is a good choice for "side sleepers"

Excellent Product !!
Bought this last year for my camper, and now I have them in my home. Very comfortable, Love it !

Great bed!
The mattress arrived in a box all rolled up and sealed. We rolled it out on the trailer bed board. It is not at full height right away but within a couple of hours it was perfect. I did buy a good mattress pad to protect it. It is firm, not hard though. We are both big people and I was worried about the past purchase we made of a foam mattress that we sunk into, making it hot and no support. All my worries about purchasing something sight and touch unseen were alleviated knowing we could return it. No risk here The first night we both slept very comfortably. No sinking in. No sore pressure points in the morning and not hot at all. This bed is as comfortable as our bed at home yay!!!

Super Comfortable
I have bought these mattresses on 4 separate occasions. Eveyone who sleeps on them loves them.

Super comfy!
I bought the bed three weeks ago and the mattress is very comfortable to sleep on!

GREAT PURCHASE!
Needing to replace mattress in newly purchased Motorhome and without being able to try it out first we were very pleased that 1.shipping time was as stated, 2.mattress is quite comfortable as well. Would do it again if need be.

We are very pleased
We are very pleased with this mattress. We purchased it for our family bunkhouse and it is working very well in that setting. We have recommended to our daughter already. Seems like a very good value for the money.

so far so good
Have only had mattress for a few weeks, seems to be comfortable, and nice for the price. was easy to open and after just a few minutes was ready for use. Time will tell how it will be long term.

Bought two
Bought two of them for my daughters about a month ago. Very happy with them. Great mattress for a great price.

Good if willing to put a few extra bucks into it
Pros: Price, shipping, delivery, ease of getting into bed room, highly rated by consumer reports
Cons: Firmness is mislabeled, requires a memory foam topper to be comfortable

I did a lot of research before buying our new mattress. We had never done a memory foam mattress before and thought we would give it a try. We went to a department store and tried out their memory foam beds to make sure we thought we might like it and picked the right firmness.

I have traveled for a job and stayed in nice and bad hotels. I thought I was pretty experienced to differ mattresses and comfort levels. This one is rated medium firmness, I would say it is medium firm to firm. It is much firmer than any mattress I have slept on. I could see how it could be firmer so I won't say it should be rated firm, but it is at minimum medium firm. There is no feeling of memory foam. There is almost no give in the mattress. You expect a memory foam mattress to give to your body a little and you fit into it. This does not happen with this mattress. I was excited to see what the pearl gel memory foam felt like. There is no indication of pearls, gel, or memory foam on the top layer.

Awesome
After researching mattresses for months and with great fear I ordered this matress based on Costco's return policy, consumer reports rating, and customer reviews. It arrived by courier ( He even dollied it into our bedroom )! It unpacked as it should. No smell , no waiting - we slept on it that night. I had left the board that I had been using on the box springs but after a 2 weeks removed it because I read that it should not be used on the floor but on box springs. It went from firm to medium and viola. Perfect!!! I've had the matress over two months and purchased gel pillows. Honestly, I've never had anything this comfortable. The gel pillows work in sync with the matress. It's NEVER hot. But now that it's winter it's not cold either. I'm just in awe when I lay down at night and even more pleased when I wake up. Great job Novaform. Great Job Costco! My first purchase from your company has made me a life long customer.

Great Mattress and Price but too firm
I have had this mattress for @ 2 years. I think it will probably last forever, but it is NOT medium in firmness. I would say at least medium firm +. You do not sink in as you do on most memory foam mattresses, but surprisingly I do sleep very well on it. It really doesn't feel like a memory foam mattress. Seems good for both side and back sleepers. I do wish it was a little softer. Slept on a water bed with 'pillow top for years until the bladders could no longer be patched. They don't make water bed mattresses like this anymore (solid pillow top and sides that drop over base and bladders. Probably this was the most comfortable mattress I've every had. Unless you like a soft mattress you will be very happy with the Serifina' and at $650 ($799 Cal King which I have)nothing else comes close.

Bought it, returned it, opted for diff product
Lesson learned- don't skimp on a mattress you spend 7-8 hours using and if you have back/neck problems. Wife and I bought this and gave it a ride for 30 days. Felt it was too soft, did not hold form. Returned it after 30 days. It came in a box the size of a dorm room fridge. That should probably be a characteristic of caution in the first place. Might be suitable product for college kid looking for something that can ship easy. Not a great solution for neck/back problems.

Deserves 10 stars!
For years we wanted a Tempurpedic so when Costco.com offered them a couple of months ago, we took the plunge. For six weeks, I did not sleep. The Tempurpedic was hot, hard as a brick, and uncomfortable. It was also excessively tall.

We returned it and replaced it with the Serafina Pearl Gel Mattress. Oh. My. Gosh. It is like sleeping on a cloud. I like a softer mattress while my husband prefers a firm mattress. We are both happy and are sleeping through the night with no tossing or turning. Do not hesitate to get this mattress!

Too Firm
Costco service and delivery and price were all great. I just could not stand this bed. It was not medium. It was very firm. Felt like concrete. I switched to the Valentina and I love it.

Too Hard
I bought this mattress a month ago and haven't gotten use to it yet. Will probably send back. Will maybe try the more expensive softer mattress.

Extremely comfortable
Having had a 15 year old firm mattress the change to this memory foam mattress its everything I had hoped it would be. Sleep on both side and back, both very relaxing and comfortable.

Great mattress
We needed a new mattress, so I researched them starting with Consumer Reports, which rated this their top foam mattress. This is our first foam, so I really didn't know what to expect. Also, we have never purchased a mattress without first trying it out in a store. It arrived quickly and was fascinating watching it expand after to cut the plastic off it. I have to say that it's harder than I expected, but I am getting used to it after two weeks. My wife, who sleeps on her back, is sleeping noticeable better. There's also no movement transferred to the other person, which is a good thing. Neither of us noticed any unpleasant smell as some have reported.

HORRID!!!!
Relying on the glowing review in Consumer Reports, I purchased this mattress more than two months ago and believed the enclosures that said it could take a while for the mattress to fully set. Well, sufficient time has elapsed and it is still the most uncomfortable mattress I have ever slept on. (It replaced a 16- year-old mattress but thank goodness I hung on to that one because I plan to put it back on my bed and give this mattress away.) The mattress is so hard, I wake up with a backache every morning and my Activity Tracker shows I am having very restless nights. I actually have to fold up several blankets and use them as padding under me because the mattress is so hard and uncomfortable. I would not even call it 'firm,' it is the hardest mattress I have owned and I always buy firm models to provide more back support. Worst money I ever spent!

Great Mattress!!
I researched alot of mattresses on their comfort, side and back sleeping and reviews and price. This one came out on top. We used to have a waterbed and thought it would be difficult to adopt our lifestyle to a regular bed. We got flannel sheets and have slept like a baby ever since. It's hard getting out of bed in the morning. Very nice.

Great Bed, Great Price
I bought this bed in February 2016 and like the other reviews found it very hard. After about 2 months, it become much more comfortable. I love it now, find it very comfortable, doesn't make my back hurt and I would certainly buy it again. You have to give it a few months and then it's great. If you are looking for a pillow top snuggly bed, this is not for you.

Great Mattress
We bought this a month ago and cannot be more satisfied. We did think it was slightly more fim then we expected but after 2 nights of sleeping we realized it was a medium firmness. The most comfortable mattress ever. Havent slept this well in years.

Perfect for me
1. I read all the reviews on the COSTCO, other sites and checked consumers overall this bed seemed to be a good choice as far as quality. 2. As you can see from the reviews some people say this bed is to hard, some say it is to soft and others say it is just right. Depending on your weight depends on how much you 'sink' into any mattress that also effects how hard of soft the mattress 'feels'. 3. I enjoy a 'firm' mattress in which I do not sink a lot into it but I do expect it to conform to my body this mattress works perfectly form me. 4. Smell: Upon delivery I set up the mattress and aired it out for about 6 hours. I then put on a mattress pad and bedding. The only way to smell anything unusual was to put your nose to the mattress and that lasted about 2 days. 5. Price: After checking warranty and cost this bed via COSTCO gave me the best value.

Very firm
I did hours upon hours of research and thinking before deciding on this mattress I read every review posted. How firm a mattress feels is different for everyone so how can you yourself decide until you have one.? I needed a firm mattress for my back issues. This one was rated so well and it was a no risk purchase. I decided to give it a try. I am a woman approx. 130 pounds. My weight didn't put a dent in it anywhere! I felt like I was laying on top of it with little to no give at all. It also took a couple of days to expand to be able to press a hand impression into it. It did not get hot, The smell of it was minimal, it is very heavy, easy set up and this is an good quality mattress. I was hoping it would conform to my body a little but it didn't. For me, it's as firm as any Firm mattress without plush or a pillow top I've tried out there. The medium firmness rating doesn't feel accurate for me or my weight at least. It's harder than the highly rated Se@ly kelburn also recommended by CR. Hope that helps as a way to compare for you. Love Costco and always will!

Novaform @costco review
If you've owned a high end pillowtop mattress you will not be satisfied with this bed, If you haven't its perhaps doable, For the money right aroud 600 dollars its worth the money, It actually helped my wifes back, And she woke up without her usual discomfort, For me it felt to firm and lacked that luxurious feel and its not something i can imagine spending 1/3 OF MY LIFE ON FOR THE NEXT 10 YEARS, That being said again its still worth the money.

Promising
We have tried a number of the Novaform mattresses. Each one seemed to have great promise but fell just short. We love the affordability and potential of the mattresses. Our first Novaform serafina pearl gel memory was too soft (rated in top 4 on CR), but nice if you like plush. We then tried the Novaform firm memory foam, which was firm and comfortable but retained so much heat that I was waking at night changing shirts from sweat. And finally the serafina pearl firm with gel, once again too soft. I must admit, I have had lower back problems, so I look for firm to extra firm mattresses. For now, we are giving up on foam mattresses.

Provides support and gently hugs you
I've been sleeping on this mattress for a few weeks now and find it to be comfortable. The mattress is softer than I prefer with a very plush top layer that hugs your body and offers support (at the lower back). You do sink into the mattress a bit which can slow you down when changing sleep positions. Before this mattress, I slept on a foam mattress - it retained heat but I feel this mattress retains more heat. My spouse really likes this mattress though. There isn't any edge support. There is an off-gasing smell that lasted up to 48 hours after unpacking. Overall: nice support, a little too soft, retains heat but I like it.

Not Supportive
At first we thought this mattress would work for us, but after a week we knew it wasn't supportive enough. We are 60 and 59, 230 and 130 lbs respectively. I am a side and back sleeper, my husband a side and stomach sleeper. I noticed that the mattress didn't hug my lumbar region while sleeping on my back. I could feel a gap there and there shouldn't be. My husband thought it was too squishy, not firm enough. What we both disliked is that the sides cave in when sitting on the edge of the bed, so you basically slide off. We had to return it and we are now trying a Sterns and Foster pillow top firm. Back to basics for us.

The best purchase ever!
We were moving to Ireland and wanted to buy new beds for everyone but we had a budget as moving countries is expensive. We gone One queen and the kids got full size each. I was very nervous as we would not be getting to try them untill we were in Ireland. However, I need not have worried. They were the best purchase ever! I normally have back issues and have never woke up even once with stifness or soreness in my back. Still totally love this bed after nearly 10 months. My only issue is now when I visit friends or stay overninght else where, the beds seem completely sub standard.

Firm cradling comfort
My husband and I bought this to replace our 7 year old tempurpedic. This Novaform 14" Serafina is the most comfortable mattress my husband and I have ever slept on. That includes all mattress's at hotels, friends' and that we've owned. We're in the mid 50 to early 60's age range. It gives a firm but soft cradling support and is not hot like our previous memory foam. We read reviews in Consumer Reports and this met our budget and was one of the top rated mattress's. We got it on sale and is a great value even at full price. Highly recommend!!

Takes getting use to.
We purchased this mattress last year for a vacation cottage. We allowed it to sit opened on the bed overnight before we slept on it. We own a pillow top mattress at our home, so this was our first Memory Foam mattress and we purchased this based on good reviews and the price. The first few night we slept terrible! We both woke up sore each morning. After about 5 nights we finally started sleeping better. I do find it to be hot, especially if you are sleeping on your back. It is soft on the top, but very firm underneath so you have good support. We are going to buy a mattress topper to try and soften it even more to what we are used to sleeping on. Overall for the price it is a good mattress, but does take time to get use to.

More of a medium firm
I love having a king bed, it is lovely! First time trying out a memory foam mattress. My husbands only request was to get a firm mattress. I would say its more of a medium-firm. You do sink in a little right away. I woke up the first week with sore back, which I never have before on my other spring mattress, but I haven't recently, so I am wondering if my body had to first get used to it. I also am 19 weeks pregnant, which could have been part of it, or that the first week we didnt have a platform for it yet!! Me or my husband havent had any issues with overheating on it like I read in some of the reviews.

Great mattress
This was a first....after shopping all over for a firm mattress, (costs were &1200-$4800+). Reviewed Consumer Reports, this mattress was very highly rated and less than $1000. Then it went on sale in February!!! With Costco's return policy we decided to give it a try. Then we learned it would be coming in a box!!! A king mattress in a box!!??!! When it arrived...in a box...flat as a pancake...there was no way this was going to work.....wrong....within three hours this 'pancake' turned into a full size king extra firm mattress!!! No more tossing and turning it's the best nights sleep we've had in a very long time...granted, it's only been a week...but so far so good. Would and have recommended this mattress to everyone we know.

Excellent !
I researched mattress online. This one came in the top 10 at number 5 . I bought this mattress 3 months ago. I always had a coil mattress and needed a change. I knew I could return it if I was not happy. Costco is great to deal with if there is a issue. It is the best mattress I have ever slept on. Extremely comfortable, not hot, my back even feels better. My wife feels the same way and she was really concerned. She is not tossed around when I move or turn over.

Firm was better than medium firm
We tried both the firm and the medium firm version of this mattress. The medium firm was available in warehouse and the firm only available online. My wife chose the firm version do to less motion transfer and no sag/roll toward the center due to my laying in the bed. She was able to get rid of a boomerang pillow she previously needed for side sleep with our Sleep Number bed that we got rid of. It took about two hours, a roll of heavy duty packaging tape, clamps, 2x4's, and a vacuum to get the medium firm mattress small enough to return to Costco...but they did take it back.

Too Soft for Us
Frankly, my one star is probably unfair, but if you love a very hard innerspring, as my husband and I do, do not be lured in by the "firm" label. That's firm for a foam mattress, not firm for a mattress in general. We sunk into it as if it were a marshmallow. In fact, after trying it for a few nearly sleepless nights, we dragged our old rock-hard innerspring mattress onto our bedroom floor and there until we were able to lift it off our bed and arrange to return it to Costco. We are SO thankful for Costco's return policy. I cannot imagine sleeping on this huge marshmallow for another night.

Disappointed
We bought the mattress online through Costco only because they don't carry California Kings in the warehouse. It two weeks to get it. Unpacking it was not to difficult. It's been a week since we've had it and the mattress still hasn't fully reached its full shape. The bottom right side is still smashed. As for comfort, the only option was to go with firm in a cal king. It's like sleeping on flat mat, there is no give, no comfy feeling. I can't seem to find a comfortable position and my lower back is achy in the morning. Will give it one more week like the instructions recommend but doubt very seriously I will keep it. Not at all what I hoped it would be, the delivery time, the shape not right and the total lack of comfort, especially for the money.

Life Changing
My only regret is not buying one sooner! I'm so glad that I took the time to go lay on a few different beds first. I even got fitted by one of those computer beds that measure all your pressure points to figure out how firm of a bed you need. Being a big guy (6' 300lbs) I'm so glad I went with the firm Serafina. You do sink in a lil little, but only really enough to form to your body. I have nothing bad to say about this bed and would recommend it to anyone.

Finally a FIRM comfortable bed.
Many thanks to Costco for their return policy. This is the second mattress I have purchased from Costco in the last six months. It is quite firm which is what I needed. The first purchase seemed fine for about two weeks, but then the "sleep impression" began to appear...sort of like a troth.

I was hesitant about buying
I was hesitant about buying and surprised to receive it in a box, but what a great mattress. I am 6'4" 320lb and the firm is surprisingly comfortable for me and my 5'3" 123lb wife, We love it. A !2" mattress might have been better, our deep sheets are not deep enough for the 14" mattress

Great Bed
I bought this bed a couple of months ago and love it. It’s the perfect firmness. It’s very similar to the Tempurpedic medium firm and softer than the Sleep Science Black Diamond. I’m a side sleeper and it does not hurt my shoulder like the SS Black Diamond did. This bed is an incredible value, especially when it’s on sale. I highly recommend it if you have laid on the Tempurpedic medium firm and like that firmness level.

Serafina Ordered Accidently...
So we ordered a "bed-in-a-box" from Costco, thinking we had ordered the King sized Novaform Comfort Grande. Shortly after receiving an email confirmation, the email read "Serafina Pearl." Initially, i was scrambling through different websites to see a comparison of the 2 beds. The Comfort Grande was said to be less firm than the Serafina Pearl. I was thinking that the Serafina may be too firm as the Comfort Grande eluded to the fact that it too was a firm bed. Now that I have received the mattress and have slept on it for a couple weeks now, I am so happy that we stuck with our accidental purchase of the Serafina Pearl. The mattress has the perfect amount of firmness that my wife and I prefer. Also, the king size makes this bed even more amazing as we often share it with our 2 kids and a 70 lb dog.

Perfect Amount of firmness
Let me start this review by saying that everyone is different. Back problems run in my family. I am only 26 and I have back issues already. I workout, I stretch, I walk, I do yoga, but all of that won't matter unless I have a quality mattress. I tried an online mattress company, and it was super comfortable, but made my back pain worse because it was too soft. This is the perfect amount of firmness. Give it a few weeks as you would with any mattress. Your body may be sore because it needs to adjust to a new mattress. This was well worth the money and provides great support. The only con I can think of is the weight. It will be tough to move. But it is worth it!

My only problem...
My only problem is that there appears to be no way to determine before you purchase what firm means when comparing foam mattresses of different companies. Our first firm memory foam mattress from Costco was 7-8 heard old and finally lost its rebound. Our new foam mattress labeled firm is as soft as our sagging old memory foam mattress. Is possible it was mislabeled? Thanks for listening. W F Bolin

Heat - Heat - Heat!
Mattress gave off unbearable heat. Not sticky, sweaty heat - just steady, intense heat. Impossible for me to sleep. For ages, at home, hotels, friends' homes, I fell asleep very quickly after laying down - usually 1-5 minutes. With this mattress, if I was lucky, I'd finally fall asleep 90 minutes after laying down. Then I'd wake up every 60-90 minutes because I needed to sit up or turn to let my back cool off. (I normally sleep like a rock!) Tried for over 2 weeks thinking maybe it would ease. Extreme disappointment as quality otherwise seemed good. Minimal odor - way less than expected. Pretty firm but not overly. But the heat was crazy horrible. Had to return.

SOFT & HORRIBLE
I just bought this mattress less than 1 week ago. I desperately needed a firm mattress following a recent bad back injury. This mattress is NOT FIRM BY ANY MEANS!!!! You sink down into it, and it's difficult to get back out of bed. The sides cave in when you sit on the side of the bed.

Best Mattress Ever!
This is hands-down the best mattress that we've ever owned! We were a little hesitant to purchase a foam mattress, having heard stories of how hot they were to sleep on and how hard it was to move in the bed. However, we have experienced neither problem. The bed is not hot and neither of us have experienced any problems moving on the mattress. We both sleep better than we ever did on more expensive mattresses and for the first time in many years, I have no back stiffness when I wake. We bought the mattress to replace a Sealy hybrid that was only 3 years old but it was no longer comfortable to sleep on. I highly recommend this mattress.

An awesome bed!
My wife and I have had our bed for about 3 weeks now and we couldn't be happier! This mattress is top quality and is amazingly comfortable. No more neck, back and hip pain. Couldn't be more pleased with our purchase. This bed is "bang for the buck". Our last bed we purchased 10 years ago and paid 4 times as much. Our new mattress is so much more comfortable and the rest we get is incomparable. Highly recommend! Two thumbs up!!

DO NOT HESITATE TO BUY
My wife and I bought a Simmons BeautyRest Mattress two years ago for $1800. After 6 months our spine/hip health started decline. Going to orthopedics etc and spending money that wasn’t necessary to find out after buying this Novaform mattress, our 2 year old mattress was the cause of ALL of our issues. We got the firm mattress and it’s the most amazing sleep we’ve had in forever. Do not hesitate to buy this mattress. For $800, it saved our hip and spine health. Do NOT get caught up in the lies of mattress store prices or sales people.
