The Serta iComfort Blue 300 is a firm memory foam mattress that is best for stomach sleepers or those of heavier builds. It comes with gel memory foam on the top layer, which will help with cooling. It isn't for everyone because of its firmness, but those who do need it are generally happy with their purchase. Some had issues with durability.

We love out Serta iComfort 300 mattress. We had a s Serta foam topper on our old mattress so we were familiar with the foam concept, but this is much firmer than the toppers. The most important thing that we like is that we don't feel each other's movements like we did before. This is a great feature of the firm mattress. We don't disturb each other when coming to bed or getting up in the morning.
So Far I've slept on the Blue 300 mattress a little more than a week. It is one of the most comfortable mattresses I've ever had. It is firm but is still very comfortable in many ways. I feel like I'm on a cloud when laying on it. Plus it still gives the support that a firm mattress usually does.
I received my mattress about a month ago and absolutely love it! I'm an insomniac and was able to sleep a full 6 hours straight! That never happens and it was SO nice! It is a firm mattress, so I didn't notice when my husband would get up during the night. Great quality and amazing support! We will be purchasing another mattress for our guest room and it will be this one!
This is my first venture outside the realm of traditional innerspring mattresses. I have been sleeping on the Serta 300 Blue Firm for about two weeks so far, and I can notice a tremendous difference in my quality of sleep. Firstly, I have actually been falling asleep quicker. In the past, it has taken me a bit of tossing and turning to get into a comfortable position. The first night, I fell asleep on my back which is something that I have tried repeatedly and has just never been comfortable to me. I have also been feeling more well rested than I have in years. I have been falling asleep and staying asleep without waking during the night to repeat the process of trying to fall asleep. The mattress is firm, but not hard in any way. I usually wake up feeling like I need to stretch and loosen up. I have noticed that my neck and back just aren’t feeling any strain in the mornings. I realized a few days in, that I was not awakened by the need to adjust the heat or fan in my room. Lastly, I have a 35lb dog that hops in and out of bed at night, there is no significant motion transfer, so I never feel him get on or off the bed.
I have back problems, but not anymore. I lay on it and don't sink like the last mattress l had. The price was right for comfort. I now wake up wide awake with no backache. Thank you Serta.
I, myself, own an IComfort Cooling Firm which was purchased in 2013
Product is consistently comfortable. Being a split set, delivery was simple into an apartment.
I've used innerspring mattresses all my life and didn't realize this was even out there. My back just started hurting and I couldn't figure out the reason. After several months, I thought perhaps it could be the mattress, as there was no support for the middle of my back. My husband and I went to purchase a new mattress and AS SOON AS I laid down on the foam mattress, I was amazed! We have had it now for a couple of weeks and I LOVE IT!!! We both go to sleep quickly, and get a good night's sleep. My back no longer hurts every time I get up. If you have back problems, I would definitely get this mattress. If not, get one just because it feels great!!! We purchased the I-comfort Blue 300 firm.
So far I love it, I have slept well,much better than my 12 year old bed. I bought two...
We bought this mattress to replace our 12-year-old Tempurpedic. We have had it exactly one week and I can't believe we went without it so long! Great support with wonderful cooling effect. I was always hot with the Tempurpedic, but not with this one! Excellent product and great price, you can't go wrong with the 10-year warranty.
I like the firmness yet comfort of this mattress. My old mattress was a beautyrest recharge less than 2yrs old it started to sag. I havn't had a good night sleep after that. Now we get a good
This was our first foam mattress purchase. It was the most comfortable of all mattress choices when we were shopping around. No matter what we tried we always came back to the icomfort. The mattress itself is very comfortable and I find myself tossing and turning much less. I find this mattress very comfortable.
Really like the firmness of this mattress and am getting great sleep!
I got my serta a week ago and it wows me every time it's exactly what I wanted firmness and coolness all in one thank you serta for making such a great mattress this was the best purchase I have ever made
So far, we have no dislikes. We needed a much firmer mattress for my husband for medical reasons, and this mattress if perfect. Very firm and comfortable. Much firmer that our previous mattress.
Best sleep I've had in a long time. When I wake up, my back is no longer stiff and sore. My arms and legs no longer "fall asleep" while I'm sleeping. Just a great mattress. Only drawback is the smell and I'm sure that will go away with time. Would highly recommend this mattress.
NO COMPLAINTS....THX SERTA!!!!!!! Sleep better than ever. Bought the Extra firm....perfect for my back.
After waking up with lower back pain for months, I decided it was time to get a new bed. After having this bed for two weeks, the lower back pain is gone! Also, I like to sleep on my stomach and side, to my surprise, I fall asleep on my back now. Wow. And dreams, I haven't had one i ages. I know I'm getting a deep, restful sleep now. Waking up before my alarm goes off too.
The bed is firm, yet you still sink in just a little. The bed does sleep cool too. I find I have to turn my fan speed down as I'm getting cold at night, in the summer in Texas!
I could not be happier with this mattress, wishing I got it sooner. I look forward to many years great sleep. We spend one third of our lives in bed, do it right!
This mattress provides good support in that I wake up and my back does feel sore. I feel that the quality meets the standard. I always wanted a foam mattress and I am very pleased with this one. I have had this mattress for a month now and I get a full night's rested sleep. I would recommend this mattress to my friends and family, as well as to anyone ready to try something new, other than the old "type" coil mattresses that we used to sleep on.
We've had our new mattress for 2 weeks now and can't rave enough about it. I had been tossing, turning, and waking up throughout the night for several years with my lower back aching. Since sleeping on this mattress, I sleep pretty much through the night and wake up with no pain at all. My husband has several issues with his back and shoulders and says this has helped him too. If one of us gets up during the night, we don't even feel the bed move. At first I wondered if it was going to be too firm, but it's not at all. We love this mattress!! (One little side note is that it still has a slight odor, which I think is common with foam mattresses and should dissipate.)
I love my new mattress and bed. I had my old mattress for over 25 years. I am hoping this one will help with my back problems. It is very comfortable and can be put into different positions. I like the 10 year warranty on the bed.
Is is the best bed. It is so comfortable yet firm. Have a bad back and with this bed I can sleep through the night and not wake up tired. I'm so glad I took the chance and purchased it.
Like the price and the quality of the mattress. We also got the adjustable base.
We purchase an adjustable King Blue 300 about 3 months ago and couldn't be happier! We were shopping for a new bedroom suite and knew we wanted a memory foam mattress for our new bed. We had one of the top brands in mind along with a couple others and to be honest, the Serta icomfort wasn't really on our radar. We were in the store trying out the mattress we had in mind, which felt really good, then the salesman suggested we try the Blue 300 icomfort to insure we were making an informed decision and since he knew we were in the market for a firm mattress. We tried it out and it felt really good as well being at a lower price point than the other major brand I liked. I reluctantly choose the Serta and wondered the whole time we were waiting on delivery, if I had made a mistake. Three months later I couldn't be happier. The mattress feels awesome, firm but conforms to the body for a great nights sleep. No more back aches in the mornings for me! Thank you RTG for the great suggestion!
I have arthritis and have had 2 left hip surgeries. This bed enables me to sleep on my left side for a little while. It is nice and cool and I usually sleep hot. I love this bed.
I had a serta mattress before this one. I liked it too but I love the Icomfort foam the best. This is definitely the best mattress so far. I sleep longer, actually want to stay in it all day. I have the base that massages and moves at bottom and top. Love it all.
I was having a lot of back issues and just generally was uncomfortable when waking up. For some reason it never occurred to me that a mattress change would make such a difference. I went out of town and stayed at a hotel with a tempurpedic. I hopped up straight out of bed, hit the hotel gym, and felt amazing. It became my life's mission to find a new memory foam bed. I was looking for a bed that didn't sleep hot. I found the serta icomfort blue 300 at mattress firm. And I love it. I have seen people recommend the tempurpedic breeze and say it last so much longer. I don't personally have $4500 to drop on a bed right now. So they may be right, but I didn't consider it. This bed is amazing and every morning I wake up well rested and not in pain. So basically there isn't a lot for me to complain about.
The serta mattress is comfortable and firm. Memory foam works great. No bounce.
Love the Icomfort bed. Last bed was worn out now I sleep soundly and comfortable all night. Also stay cool through the night. Highly recommended. I researched before this purchase and went to many stores and tried different mattresses, was very pleased with this purchase.
What a difference a quality and comfortable mattress makes. Unbelievable how much better the support is and how much better I sleep. I don’t wake up sore or stiff like I used to. I can’t express the complete satisfaction I have with this mattress. I will be buying Serta for the rest of my life. Thank you Serta, Suzanne
The Blue 300 Firm is awesome. It is so comfortable and I love the way that the mattress does not move when someone else moves. Myself and my husband were having back pains, now its hard to get out of the bed. Love it.
I have always woken up with migraines. Within the last two days of having this mattress I haven't woken up in pain! My husband has severe back issues as well and needs the good level of plush and give but also support. He has that now. I can't give enough stars to this mattress. 10 out of 10 will buy again when we have to buy a new mattress which hopefully won't be for a while.
I love my I series cool gel foam. We have a King size now and we do not want to get out of bed. I work 3rd shift and it was hard for me to sleep because it is so light out but since I've had this bed, I sleep like a baby. I sleep an entire 8 hours. We also purchase the base that adjusts at head and feet. It also massages. Oh my, it's the Best. We had a serta queen size before but we absolutely love this one.
I love this product. I moved recently and was just using a blow up mattress and then decided I need something a little more suitable for my back. I saw the ad in a magazine. So I went to go see for myself at Same Club and purchased It right away. Amazing an incredible comfort. I love this mattress topper !
* If you have a bad back, this is the mattress for you. * If you toss and turn, this is the mattress for you. * If you want to sleep better, this is the mattress for you.
Love the double pillow tops. Great sleep over last mattress I owned.
When we were in the store looking we didn't know anything about these mattresses, but when we laid down on it we said this is it.
The mattress quality and comfort is second to none. It is by far the best value on the market! It stays cool all night and dissipates heat providing a comfortable surface area without having to re position for comfort. We selected firm and it is but just as firm it is very comfortable and contours easily.
I LUV LOVE EVERYTHING ABOUT IT WENT TOT SEASTO BUY IT MUCH MORE COMFORTABLE THAN MY PREVIOUS MATTRESS I EVEN LIKED THE COLOR BLUE-----I'M A MALE,THAT HELPED------LOL
My husband and I were a bit afraid to purchase a mattress set online. But luckily found the perfect mattress set for us! We both have back pain, which this firm mattress helped with. We now get good rest at night and without pain like before on our backs. Truly recommend this mattress! We are truly satisfied with this mattress that has a good comfortable firmness to it!
Bought this to replace rental mattress. Great night sleep and stays much cooler.
We have only used our Serta iComfort Blue 300 for about a week now, but so far the mattress has been such an improvement over our old traditional coil mattress. I was not sure how I would like the foam mattress but it really is comfortable and firm.
I have been wanting to buy an Icomfort for awhile but was a little weiry on spending that type of money on a mattress. I found the mattress on sale for the holidays and I had to get it. I have a few chronic health conditions that make buying a bed challenging; as I need a soft bed sometimes and a hard surface sometimes to sleep. The first night I didn't think I would sleep well because it was not broken in yet; however I slept over 10 hours :). I can't wait to see how well my body adjusts in the upcoming weeks and months.
Recently purchased this product to replaces a close to 20-year-old Serta box spring. Initially, the mattress felt strange on the body due to the heat from your body and the contouring of your body to the mattress. It is warmer and requires a bedroom with an air conditioner. My tightness in the neck, lower back and hamstrings disappeared. The quality of sleep improved which boosted energy levels. The bed is so comfortable it is a challenge to get out of bed in the morning. Save your money from purchasing a tempu pedic. Buy the adjustable base which adds comfort while watching tv. There are many retailers to purchase this fine mattress. My suggestion is Sears since they deliver, set up and haul away your old mattress and boxspring at a nominal cost.
This mattress is the best ever!!!! With my previous mattress my back and neck hurt every morning, I woke up tired everyday, since I bought this mattress I am more rested. I highly recommend this product.
We bought the iComfort Foam set as it was the most comfortable we had tried and it came with great reviews and an excellent warrantee. Definately an upgrade over our old (less than 5 years) Simmons conventional Set. My wife and I have been sleeping better every night since it was delivered.
So far we love it. Getting better sleep at night. We tried different manufacturers and Serta beat them all.
Great mattress. Nice and cool. Getting better sleep, and easier to wake up in the morning.
We was sold the moment we laid on it at the store. We tried out a few other bed but at the end this was the one. And the cool factor when you lay on it was very nice. I would recommend this to anyone
Our old mattress and boxed springs were no longer comfortable! This one, after one night, was amazingly comfortable!.....We both like the firmness of the mattress very much. We look forward to years of comfort from our Sealy mattress !!!
Since sleeping on this bed, a lot of my back pain has resolved. I even notice that I feel more well rested.
Really improved my sleep quality already. Gel foam does help cool and provides firm support.
Our new mattress is wonderful for my sleep now. My physical needs changed since our last mattress which was 12 years old. I developed arthritis in my hips which made it painful to sleep on our previous mattress. We went to visit my cousin who had just purchased this mattress . She let us sleep on it while we were visiting. It was the best sleep I had had in a few years! It was cooling and so comfortable...no pain in my hips! As soon as we returned home, we went to purchase our very own. Love it!!! Had it a couple of weeks now and can't imagine being without it...ever!
This is our second foam mattress. The newer ones have nice improvements. You can see and feel the difference in the layers of the materials.
The mattress is very comfortable and I love the cooling effect. I have had foam mattresses before and always felt that they slept hot which made me uncomfortable. I don't have that problem with this mattress. I also appreciate that the edge of the mattress is a bit firmer than I have seen in other foam mattresses which makes it easier to get in and out of bed. Overall I love the mattress and highly recommend it.
Love the product. Wake up feeling well rested. Would recommend the mattress set to everyone
When my husband and I went mattress shopping I was totally against a memory foam mattress. We went to Sleep Experts and got a recommendation by using their support analysis machine. We ended up purchasing a Serra icomfort blue 300. I have trouble sleeping, getting only 3.5 to 4 hours sleep a night. Arthritis in my hip would cause me to wake up with hip pain and then have trouble getting back to sleep. With our new mattress I have increased my restful sleep by 2 to 3 hours a night. I no longer wake in the middle of the night with hip pain. I get great restful sleep. This mattress is a great product. I am looking forward to better sleep and the benefits that better sleep will bring.
Best night sleep I have had in a long time. I have a bad back and shoulder. I used to toss and turn. Now I am very comfortable.
I have hip, back, and neck problems stemming from an old car crash and have had difficulty getting comfortable and staying comfortable in order to get a good night sleep. Not so now! The very first night of sleeping on the Blue 300 firm mattress by Serta was one of the most restful nights I have had in years and each night since has been the same! I was never a fan of a firm mattress but the Blue 200 firm is in a class by itself! Not only is it firm but the memory foam is soft and provides just the right amount of support to ease my aching body after a long day! The queen size provides plenty of room for both my husband and myself to stretch out and not feel crowded. We both are in love with this mattress and look forward to a long time of restful sleep!
Bought the Blue Touch in a Twin XL size to form a split king with my wife. I am so comfortable whether sleeping on my back or on my side. No back issues and I wake up genuinely refreshed! I had some concerns as I had never had this time of mattress before, but our salesperson, Irma Salas, in Lubbock gave me great advice on trying this one out. So excited and relieved to know that I've got several more years of great sleep ahead of me!
My wife an I have been searching for a while when we discovered the Serta 300 Firm. We tried several others but kept coming back to the Serta. its just right!!!
I was a little skeptical of foam beds, but I knew this was the mattress for me when I tested it in the showroom. After sleeping on it for three weeks, my first impression was spot on. Even though it's "firm" I feel absolutely no pressure points and wake up without the aches and pains from my previous firm mattress.
We found it a better value than the tempurpedic. We tested both in a store and found the Icloud a better value.
we were surprised on the difference between the foam and our old pillow top. It took me 2 nights as the new mattress was firmer than our own. I can get out of the bed without disturbing my partner as the the new matress does not have a wave or bounce effect. Get yours now. Retailer gave wonderful service and deliver and set up and hauled the tired old mattress and box spring away
Best mattress ever! It Greatly Improved sleep and very comfortable sleep!! Thank you Brandon @ Mattress Firm!!
My husband and I needed to replace our old king bed...and wanted to try foam mattresses for the first time. Well, I wish we'd bought a Serta IComfort years ago! I have a very bad back and have not had any pain in the morning since purchasing this Blue Touch 300 Firm. Heavenly comfort and cooling relief that helps hot flashes, too--YAY! I love that Serta offers a split mattress option--so we both got the firmness we wanted side-by-side. Perfection! I highly recommend the iComfort line of foam mattresses. You will be very happy like I am. Thank you, Serta.
We bought iComfort Blue 300 mattress. This mattress is good and doesn't warm up in summer as compared to our previous memory foam mattress. It is sturdy and comfortable at a affordable price. Love this mattress as my sleep has improved.
We love our new Serta mattress. The memory foam is great and the mattress is cooling.
The first night I thought this bed might be too firm. But it isn't at all! We've had it about three weeks now. I sleep through the night and am not tossing and turning any more with low back ache. My husband has several issues (back, shoulder, arms) and says he's sleeping much better too. I don't even feel the bed move when he gets up in the night like with our old bed, therefore no more disrupting my sleep. I love it so much I even bought this same mattress for our guest room.
Our Comfort Foam Cal King is amazing! We were having back and neck pain prior to purchasing and now it is gone, we get a good well rested night sleep. I have purchased smaller sizes for my kids and they sleep better and have a better day the next day. It also keeps us cooler during the night which helps us breath and sleep better . Highly recommend !
I liked the value behind this product and the appearance. The foam is forgiving, but still provides back support.
These mattresses suerpassed the comfort of the last two we have owned. We have been sleeping very comfortably. We are so grateful the salesperson promoted serta icomfort. We will never buy any other brand now that we have slept on the best. Thank you serta!
Love this product amazing company I would recommend it to everybody I sleep so well now
Right from the start I had a full nights rest. We previously had a temperpedic and loved the bed but it was getting to hot to sleep at night we were going to buy another one until we found this one just by chance. Best thing we ever did i feel fully rested after 5 hrs of sleep, that's because when I fall asleep i don't get up anymore I sleep thru the night every night. Also way more affordable also which is a plus but that was never even a consideration when we going to buy a bed.
We have a Serta Pillow top previous to this new one, it did not work that well. I highly recommend this mattress. I can sleep much better. I am very happy with this purchase the temperature of the mattress is great and its feel very comfortable.
I was looking for a very firm mattress. Every other one advertised as "firm" just weren't cutting it. I tried this one and instantly was sold! I've had it for about 3 weeks so far and it's been great!
We love the bed. My sleep has improved. The only difficulty is finding sheets to fit correctly.
I have enjoyed the mattress. My back does NOT ache when I get up in the morning. I am very pleased with the purchase.
I used to wake up with back and shoulder pain every morning, I finally decided I had to buy a better mattress and maybe that would work. I love this mattress! I sleep a lot better and have never woken up with any pain at all. This mattress is well worth my investment. I would highly recommend it to all my friends, family and co-workers
We upgraded to a king size bed so we had to purchase a new matteress. We has a sealey mattress before. I have degenerate disc disease in my back so needed a firm but comfortable matteress. We decided on the Serta Icomfort and We both absolutely love it. We sleep comfortably and wake up with no back pain. I would highly recommend this mattress for others with back issues.
Like this one better then the 500 plush. Firm and comfortable.
I have not slept on the mattress yet we just had it delivered today. Both mattress and box spring were wrapped in plastic. We cut the plastic off and the mattress does have an odor to it. Almost like a dry cleaners smell. But its not as bad as I have smelled before on similar material products. We plan to 'air it out' for a bit. I look forward to sleeping on it. It is nice looking and just laying on it, it felt like a dream.
Like the firmness was planning on the Blue 100, then tried at store and liked the how firm the 300 was
Really comfortable and sturdy mattress. We purchased a firm and it is just the right amount of firmness. We've had it for 6 months now and it holds up great. Can get in and out of the bed without disturbing each other.
Likes: Very comfortable and supportive in all positions! At first I was worried it wasn't firm enough because you sink in slightly, but it is. Great for side sleeping...no arms falling asleep. Dislikes: I wanted a mattress without hard piping/wire around the edges because I sit on the side of the bed a lot. The edges are kind of soft and rounded...you sink in a bit and it is not good for sitting. But it's great for sleeping which is, after all, its primary purpose.
great foam feel. you'll have a blast with a serta adjustable base and the right sheets. so far have slept great.
The product is very nice love it. I would recommend it to anyone that's fine a new mattress set.
The bed is very comfortable. I sleep good through the night with a lot less tossing and turning. I thought it was hot but I found out there is a matress pad available that is supposed to make sure the cooling gel is able to get through. I just ordered it.
weve had this mattress for a only a month. it is very comfortable
took a bit to break in but now we love it the sales person was great we are happy
I prefer a firm mattress. I obtained relief from lower back pain within a week sleeping on this mattress. I would like to add that when I filled out warranty information I was not able to indicate my correct state in address which is MN.
The bed is very comfortable to sleep in. It is supposed to be a cooling bed but it does feel a bit hot at night but I found out from calling the company that it might be my mattress protector that I have so I have just ordered the one that goes with the bed. The bed is great to sleep in
We are very impressed with the quality and appearance of the iComfort Blue 300 Firm mattress. We have experienced no off-gassing and the cooling feature keeps us warmer than our previous mattress but not as hot as standard memory foam. Overall, we like the mattress and hope that over time, it will lose a bit of its firmness to be more similar to the floor model we testing in store.
very firm,and its light enough for me too pick up and put sheets on my sleep is alot beter.my other one was not firm enough love my new one
On our first night sleeping on our first all foam mattress, we slept like a rock! We woke up with no back pain, and very well rested. I don't know how it's possible to feel like you're sleeping on a brick made out of clouds, but that was our interpretation. We needed a mattress that was very firm, and this delivered! Great value as well. Highly recommend this mattress!! We are very happy with our new mattress and look forward to many more well rested nights.
This mattress is very comfortable. Mattress is great quality, will last a very long time. My husband loves firm mattress so this one is ideal.
This a great mattress for the money. It's very firm. I like a good firm mattress, but it may be just slightly too firm for me when I'm sleeping on my side.
i love my icomfort mattress because it's more firm than my last mattress. The pain in my back and hips have not gone away but have diminished quite a bit. The mattress is very firm and I'm trying to get use to it. I may return it for the gentle firm version but I want to give it time to see whether or not I'll get use to it. Overall I'm happy with my pruchase. The quality is awesome!
I have had my Serta IComfort Blue 300 Firm almost a month and I am happy to say my achy back is much improved!!! Happy with my purchase. I give this high marks of satisfaction!
It's new fresh comfortable and is giving me a much improved sleep.
Takes a little while to get used to the foam. Wish we could afford the adjustable part.
I had had this mattress for 3 months. I initially though i wanted something this firm since I sleep on all 4 sides. Back and stomach sleeping works just great, not so much for side sleeping. I will be replacing it with the Blue Max 1000.
I'm a little disappointed as this bed was ALOT more firm when it arrived than it was when we tested it in store. After over a month, it's getting a bit softer but not at all when I had hoped for.
adjustable base stop to work after just 4 years , 1 hour waiting in the phone and I never pass automatic answering system
I am a side sleeper and my hips hurt every night after sleeping on this mattress. I thought the foam mattress would give a little as shown in the graphics but so far not.
I already have breakdown in the middle of the bed. Not satisfied.
