However, overall, with a variety of mattresses in different thickness options, Novaform gets some good initial feedback from customers. Still, there are some reported issues with heat retention, firmness, and initial comfort in some cases.

Cocoon's Owner Satisfaction

Having great customer satisfaction is essential to both mattress companies and mattress shoppers. These mattresses get higher marks from customers than many other competitors, which should give you confidence in learning more about them. Keep looking below to learn how this mattress will work for you!


Cocoon's Supportiveness

These mattresses are quite supportive. Customers report that their hips and shoulders are cradled while their spines are properly aligned.

Edge Support
These mattresses also have good edge support, which is how a mattress does keeping its firmness from its core to along its sides. For those that like to roll close to the edge of the mattress, these mattresses will do a good job being supportive to your body.

Bowling Ball & Density Tests
The bowling ball test is a great indicator of firmness, and it can also provide guidance on the difference of firmness throughout the mattress. Therefore, it is helpful in showing if there is even support throughout the mattress. Based on this, these mattresses do well in their supportive eveness.


Cocoon's Durability

Having a mattress that really lasts can mean thousands of dollars saved for you and your family. This is one of the reasons that customers strive so hard to find mattresses that last. However, unsurprisingly, there are lots of brands that are more concerned with their immediate bottom line. Even in spite of that, there are still some great brands that build good products. These mattresses are given high marks when it comes to durability. These mattresses should do well for you unless you have a bigger build or use the mattress more than average.

Novaform's Owner Satisfaction

Sleepers don't always feel excellent about these mattresses. Some sleepers report feeling satisfaction with their new bed, but others not so much. Therefore, it is hard to understand if one of these will keep you totally comfortable. Continue reading below to learn if one of these mattresses will work for you.


Novaform's Supportiveness

Support is a bit different than firmness. Great support is when your mattress aligns the spine and leads to a better night sleep. Overall, these mattresses have some negative reviews when it comes to support. Most find the mattress to be comfortable at the beginning, but some customers didn't feel supported well over time.

Edge Support
For those that like the lay close to the side of their mattress or have mobility issues, even edge support is very important. These mattresses do a good job at edge support initially, but some found that it wasn't as supportive as they'd like


Novaform's Durability

Mattresses that last a long a time are great, but not always easy to find. Sadly, sleepers don't rate these mattresses well when it comes to durability. That said, some mattresses may last a significant time without problems, while other sleepers may find their mattress falters quickly. If you are bigger in body type, take a look at the reviews before purchasing.

Cushy support
Just what I expected but I might need to exchange it. I bought the soft mattress. It feels like foam on a rather firm, supportive mattress. Sounds ideal for a side sleeper, but I'm waking up a bit sore in lower back. Honestly, it could be my medicine dose. I have to do a good trial with better pillows, regular dose of my medicine to be scientific. Arrived a day early. I managed to unpack it on my own. I'm a short woman with back pain and I didn't hurt myself unpacking it. It would be super easy for two people. I'm very happy i can exchange it if i need to.

I No Longer Wake Up Every Couple of Hours!
The process to buy the mattress was so painless. It was so much better than stepping foot into a mattress store - I will never do that again. My husband threw his back out and we desperately needed this new one. So I called customer service and told them what happened. They were SO helpful and actually over-nighted the mattress to us so my husband could recuperate faster. I am very grateful. One thing to note - even though we have the "soft" version, it is much firmer than what I was expecting. It's not one of those foam mattresses than can be difficult to move around in. This definitely has a good amount of firmness to it. Even my husband, who loves a good, firm mattress, says this is great for him!

No more pain in the morning
For the first time in months I wake up rested and NO back pain.

Very comfy
Still enjoying a great nights sleep on this mattress! Seamless process from selection to delivery to set up.

Love our new cocoon!
Delivery was timely, package was easy to open, mattress came to life immediately. Our mattress is firm and comfortable. We love it!

Amazing bed
The morning after sleeping on it, I got out of bed and starting saying, "My back hurts." As soon as I said it though, I realized it wasn't hurting! I was just so used to complaining about my back hurting that I did it automatically without even thinking. It keeps me very warm a night!

I'm diggin it
I've only had my mattress for about 2 weeks now but so far I'm happy with it and am definitely sleeping better. It really is more firm than you would expect out of a "soft" mattress but it's actually what I prefer. I feel like I have more support that way. My best friend has a Leesa and my Cocoon is definitely a bit firmer than hers. I've bought foam toppers in the past and they never held up over time. I am hoping this foam mattress doesn't let me down. I have to say it is a really good deal compared to other bed in a box companies out there and the reputable company name sold it for me. Of course the great reviews helped too ;-) I plan on updated my review in the future to let you know how it holds up over time. Good luck, friends!

Ordering them for every room
We love, love our new Cocoon mattress and foundation. I don't want to get out of bed! I'm now ordering them for our son's room and our guest room, too! Great customer service when I reached out with questions.

Just what the doctor ordered!
What an awesome mattress. The only thing I would suggest re: the cocoon would be to unpackage/wrap it on the floor completely before putting it on your bed frame. You have to take it off to get the last wrap off anyway.... Money well spent, very worth it, we will see how it holds up in the next few months before we come back to update our comments.

Nice design and easy to handle
I just wish it is firmer. However, the piece is not firm enough for me so I have to return it.

Best money I've ever wasted!
This bed is very firm. From my personal opinion, I would give this bed a 7.5 out of 10 on a firmness scale. This bed causes me to wake up with back and neck pain, that I did not get from my older SPRING mattress. As for the "chill" cover, it does make the mattress feel a slight bit cooler to the touch, but after 15-20 minutes of laying in bed, you can kiss that coolness goodbye!

Enjoying a good nights sleep
Thanks for the great bed.

A better nights sleep.
The Chill Soft mattress was a great purchase, as it has given me a better nights sleep during the day, as I work nights. I have had problems with other mattresses, due to back aches from work, but the Chill Soft has helped ease my back pain. The Chill Soft does seem to sleep cooler than my old mattress, though not as much cooler as I wish it would be.

WE LOVE IT!
I bought 2 twin for my kids and they loved it! Firmness is just perfect. We currently have a Serta bed that we paid over 2k, some spots in the bed are now too soft and the edge support is really bad. Tried to claim for warranty but it seems like they're doing everything they can to not cover it. NO MORE SERTA FOR US!

Cool and FIRM
The mattress is very comfortable and keeps my hot sleeping husband cool as advertised. It is on the firm side of firm but otherwise we are completely happy with our purchase. The delivery and set up were super easy, too.

Sleeping Beauty
I am a very sensitive sleeper, but once you lay on this bed you go off to wonderland! Usually, I get up several times during the night but with this bed, I'm dreaming and or sleeping until morning. The con is sometimes my ears or shoulders are little sore from being in such deep sleep but your body gets used to it and adjusts. Now I can't sleep on anything else. What am I going to do when I travel now?

Easy and Comfortable
Mattress arrived on time and was easy to open and set up. It is very comfortable both for me and my husband.

Love it !!!!!!
Wish I would of bought one sooner . Haven't slept this good in years!

Love is sleeping on a Cocoon
So easy to purchase. So easy to unbox and unpack. So easy to place on a boxspring. So easy to sleep on from the first night. My Cocoon is the best bed purchase I've made.

Not a 5 because..
Great mattress and I feel the wooden slat in the foundation.

Restful sleeping
First night was kind of rough but I think my body was adjusting to the new bed. After a few days of breaking it in I found that I'm more refreshed and limber with no more back pains. I would recommend this bed to anybody who's in the market looking for one.

Great mattress!!
I love everything about this bed super easy to put together and the mattress is so comfortable. I got the chill king mattress best decision, I couldn't be happier!

No more pain
This is my third cocoon mattress. I initially purchased one for myself a year and half ago, I love it so much that I bought my mom a cocoon classic and a cocoon chill firm for a dear friend who was having back issues. They both love it and their aches and pains are gone. To top it all, unparalleled customer service.

It's a great bed
I purchased this bed back in March 2017. It's now November. I love this bed now but I didn't love it when I first purchased it. I felt it was as too hard even though it was the soft version. However, my husband really liked it so instead of returning it, I bought a memory foam topper. That helped immensely. I now get amazing sleeps. I would definitely recommend this bed. The price was good as well as I had a coupon for $100 off.

Loved the Coolness
The mattress cool at night. It is also very comfortable and great on my back.

Almost perfect
Great support. Keeps me cool and comfortable. Best purchase I made last year. My only criticism is that the edges of the mattress are strangely too soft, softer than the rest of my firm mattress. It is too easy to slide off the edge when one sits to put on shoes. Otherwise, best mattress ever!

The most comfortable bed in the gouse
We recently got the cocoon soft mattress for our daughter. It is hands down the most comfortable mattress in the house and is great during story time.

A great night sleep, finally!
Love how cool my mattress stays and its amazingly comfortable that i don't want to get up in the mornings.

Love it!
Our new bed is so comfy! I have been happy with it since day 1. Ordering was so easy and so was set up. I will definitely buy another one for our guest bed.

nice but it smells
I like the bed, but unfortunately it smells pretty bad hopefully the smell does away. I slept on it the first night and the next morning I felt dizzy. maybe it was the weather outside or something, but it could of been the flumes from the bed. I would suggest to anyone who buys this that they put it in a room after it has expanded and let it air out for a week. who knows maybe two weeks. I ordered a firm mattress, but maybe I should of ordered a intermediate. I don't get into it and say aww that is so comfortable.

Super comfy and super affordable
It was so easy to get this delivered to my new apartment and I didn't have to wait for delivery men. The mattress is comfy and afforable.

So comfy!
It took a bit to get used to the difference in a foam mattress compared to a typical spring mattress. After the initial few nights of getting used it, I can't wait to crawl into bed at night!

Finally a good night's sleep!
We always purchase a firm mattress and this mattress is the firm we desire! The customer service agents are very helpful in answering any questions before purchase. It shipped quickly and was easy to set up. Thank you Cocoon for giving us a good night's sleep!

Soooo comfortable!!!!!!!
The way it's made and the ease of ordering and receiving it. The thickness is great, easy to get in and out for an elderly person.

Most comfortable nights sleep EVER!!!!
I Love that I feel like I'm getting a full body hug while I sleep! Not too firm, not too soft, a perfect snuggle!! Love it!

"Best Guest Mattress" - every guest
I bought this mattress to put in my spare bedroom. Since purchase, I've had a few guests stay over and tell me how great the mattress is and that they were surprised I sprung for one of those -pedic mattresses that cost so much money! I tried the mattress out for myself one weekend, and decided to order a King for my bedroom. I usually toss and turn at night, but woke up in the same fetal position I laid down in the night before.

comfortable
a comfortable mattress but soft feels too soft to my standard. Would be better if there is another choice between soft and firm!

Over the moon happy w/ my Cocoon!
The delivery process, unfolding and making the perfect bed to fall asleep in....I love this mattress and really pleased with the right amount of firmness for the "firm". Not too hard, and definitely not too soft--just RIGHT! Thank you Cocoon for making my nights better :)

Finally a great night's rest!
Comfy. Sheets don't stay on well. Best sleep I have had in a while. Don't have to have my back popped back into place every day anymore.

LOVE THIS BED!!!!
Bought this bed after doing extensive research on different brands. The Cocoon bed came out a winner, far ahead of the others. My Cocoon bed was delivered promptly and set up a super easy. This is hands down the best bed I have ever slept on. I love this bed!

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.
