The Serta band mattress is made of very good quality and is certainly impressive. It molds to your body and just the right firmness. Initially there is a strong order when unpacked but it didn't seems to come through the sheets.

The most comfortable mattress.

Submitted by tracymshaf - 11/15/2019

I have finally found the mattress of my dreams. I have struggled my whole life with trying to sleep without back and neck pain. And I am always hot when I sleep. This mattress with the cooing gel is the most comfortable I have ever had in my whole life. I finally get a full nights rest free from pain.

Works for couples who sleep different

Submitted by kaylac84 - 11/4/2019

Finding a mattress that works for us both has been a challenge. He is a back sleeper that moves alot and I'm a side sleeper. Since I'm also a light sleeper, I wake often to him moving. Both of us noticed right away that we were sleeping better at night. He didn't toss as much and I couldn't feel him moving. Win Win situation! I was a little worried at first with the firmness of the mattress for my side sleeping. I've always used soft mattresses. It surprised me though. Firm, but it was soft enough for my comfort. I also noticed that my back pain has lessened as well. It's sturdy and holds it shape well which makes it comfy even if you sleep near the edge of the bed. We really love the cooling feature of the mattress. My husband is a hot sleeper, even in winter, and not once has he woke up sweating. Its almost a little too cooling for me, but I just compensate with an extra blanket on my side of the bed. The only problem I had was the smell of the mattress when it was unwrapped. It was very strong and had to air out the room and mattress for a couple weeks before using it.

Supportive mattress

Submitted by Mulleka - 11/2/2019

I have had this mattress for about a month now. I wasn't in love with it at first. It felt too firm for me, and very uncomfortable. Few weeks went by, the mattress aired out and softened up to medium firmness. I love my mattress now. This is my first time sleeping on a memory foam mattress, and I'm never going back to innersprings. The memory foam molds the mattress around my body and gives me the support I need. One thing that worried me about memory foam was how hot it'd be. Serta iComfort CF3000 has a cool-to-the-touch cover and UltraCold System with Carbon Fiber Memory Foam that keeps me cool throughout the night. I've never slept so comfortably. I'm very happy with this mattress, and I think it'll last many years to come.

Submitted by MontanaMustang - 11/1/2019

I've had this wonderful mattress for about a month and I love it! It is the perfect balance of support and comfort! It has really decreased my tossing and turning because I just melt into it and it cradles and supports me. I highly recommend the iComfort CF3000 Medium mattress. I sleep so soundly and comfortably with this mattress. It is aptly named the iComfort. This is the first mattress I've really loved from the first night.

Sleeping on the clouds

Submitted by Bonbon88 - 10/19/2019

This mattress is incredibly comfortable with just the right firmness that makes me wanna go to bed earlier every night! I feel as am sleeping on the clouds and the memory foam hugs me everywhere yet still gives the right firmness and support! But to be honest my favorite part of all is the cooling features of this mattress which in my case has been a lifesaver! I have been getting night sweating since i gave birth to my little baby girl 2 weeks ago and my doctor said this might continue for the whole 6 weeks postpartum however since we received this mattress from Serta, and replaced our old mattress the cool to touch system of this one was just the cure! It absorbs all the heat from my body and keeps me cool all night! No more heat no more night sweating!! Cheers to many more peaceful nights to come!

My chronic low back and neck pain is gone!

Submitted by LaLa59 - 10/19/2019

I thought I had a decent mattress but have been experiencing alternating back and neck pain. Now I know what a quality mattress feels like. I've only been using it for about a week or so but I've already noticed a difference. I'm not getting the same sort of pain when I wake up, it's amazing. I am optimistic that this will continue. The mattress is firm yet is very soft and comfortable, it's easy to get in a nice sleeping position without much effort. I really like it cold while I'm sleeping and I can still use a light weight blanket now because this mattress doesn't add any additional uncomfortable heating sensation while I'm sleeping. It's a bit taller than my old mattress but my sheets still fit it fine. Highly recommended mattress!

Great overall mattress!

Submitted by Lpena - 10/18/2019

My favorite thing about this mattress is that I do not feel my husband get in and out of the bed as he has to start work really early in the morning. He loves that the mattress keeps him cooler than our old one as he tends to sleep hot. The mattress itself is pretty comfortable while still being supportive as I received the medium-firm mattress. The only thing I didn't really like is the chemical smell that you have when you get a new mattress however I know that is pretty typical with new mattresses and it fades over time. All in all a great all-around mattress!

Very Comfortable

Submitted by Babyhawaii425 - 10/16/2019

I usually toss and turn all night because I can't get comfortable with my back and hip pain from a car accident. This is the first mattress that has help alleviate that pain almost 100%. The mattress is firm enough to hold its shape and that you don't sink into it but soft enough to conform to the main pressure areas while sleeping. The bonus feature is the cooling feel that mattress gives off. No more hot sweaty nights. Overall, it's a great mattress and very comfortable.

I got this for my 13 year old who was having a tough time sleeping. The minute he laid on it he wanted to take a nap! It is the perfect combination of comfort. Its a firm enough foundation that your not sinking into it, but still soft enough for an awesome nights sleep!!! Definitely will be purchasing another for our other rooms!!!

Best Mattress I've Slept On

Submitted by Aaron330 - 10/5/2019

I'm very pleased with this mattress. When it comes to the softness of this mattress, it's for sure a medium but on the more firm spectrum of medium. It has just enough softness (roughly 4 inches of soft foam) that you aren't sinking into the bed when you sleep. Yet it's firm enough for us side sleepers that it gives you the proper support your neck and back needs. I seem to fall asleep faster sleeping on the mattress. I also love that this mattress doesn't retain body heat and keeps you cool throughout the night. I'm warm blooded so I can appreciate that! One downfall I have is the smell of the mattress when you first take it out of the shipment packaging. It had that factory off gas smell to it. It is expected when you purchase these types of mattresses. I let it air out for a couple of hours before putting fresh linens on. The smell fully dissipated after 3 days. Another possible downside would be that you might need to purchase deep pocked bed sheets since the mattress is on the thicker side but you can get by using your regular sheets. In all this is a great mattress!

Love this bed!!!

Submitted by JeniJenJen - 10/5/2019

I wasn't sure what to expect when we set this bed up in our frame but I had high hopes. My husband is a sleeping sweat factory and I keep trying different things to alleviate this issue. I've tried different blankets, sheets, fans, weighted cooling blankets, you name it. So we put our sheets on the bed then later slept in it. It is very comfortable, first off. I've been in so many car accidents that my poor back doesn't like many mattresses but I sleep nicely on this one. It's cushiony but firm. Perfect. But for the real test: can it keep Mr. Sweaty from leaving his patented wetness everywhere? I'm happy to say so far so good! He's comfortable a I'm comfortable and I don't roll over into piles of sweat which makes me very happy. If you're in the market for a product like this you need to give this a try, you won't be sorry.

Very firm, but still comfortable!

Submitted by marissacre - 10/2/2019

If you're looking for a soft mattress, I would suggest you go one level softer than you truly want. I got a medium mattress and this thing is rock solid. It still has enough cushion that I didn't need to send it back, but it's something you should be prepared for. It is also a very thick mattress so you may need new sheets if you don't already own deep pocket ones. As far as the other features, the carbon definitely keeps you cool! I'm a very hot sleeper and this mattress feels cool all night. It is very plush and feels like a nice compromise between soft memory foam and firm springs.

Can go with the adjustable frames

Submitted by Maggie90 - 10/1/2019

So I ended up getting the queen medium firm mattress. This is so comfortable and I'm so happy that I got to have this. I don't like something that is too firm, nor, to plushie. I have had a lot of back problems and sleeping problems for a longtime so for me, having something comfortable is possibly a bit more crucial than some.I also am the person can have blankets on top-of blankets with their feet exposed or has absolutely no blanket but just covering my feet. It is very hard for me to sleep through the night comfortably with regulating temperature. It almost becomes frustrating to me. This has the memory foam which I already loved but what made an excellent mattress was the cooling gel so it allows you to have a more regulated temperature while you sleep and it just evens everything out. It gives you a more comfortable sleeping experience. I do have a spouse so what I love is that I really don't bother him when I get up from bed or move. I feel like this mattress will last a while and will remain very comfortable. Though I do not currently have the bed frame Allows you to customise your leg, had support, Etc, this mattress is compatible with those type of frames. In my opinion this would be a great mattress for anybody that likes the medium type of mattress is because it will provide the perfect support with the good amount of plush also. I would definitely recommend this brand but I would most definitely recommend this specific mattress. After looking through the stitching, the time and quality of this mattress, it is so worth it. Though I really love this mattress, this is not a concern at this time but I definitely wonder if the gel well last as long as a mattress without gel would last. Like I said I still feel this is an excellent mattress but this would be the only possible con I could possibly think might malfunction but this is just a theory, not something that has happened.

Comfortable

Submitted by EveNV - 10/1/2019

This mattress is so comfortable! I could just be imagining this but since receiving it I fall asleep faster and stay asleep longer. The only con I have is the smell the mattress had when I first got it. I can't even describe it, like chemical smell. Since it is my only mattress I couldn't just leave it outside to air it out. It took me 2 weeks to get rid of the smell. Now that the smell is gone it's perfect! Definitely recommend

Great mattress

Submitted by Cinbu48 - 9/30/2019

I've been looking for a new mattress and this one is wonderful! It feels like I'm sleeping on a soft, but firm cloud. It supports me in all the right places. It isn't very bouncy, so children can't use it as a trampoline! It looks a bit bigger than my old mattress, but all my sheets and comforters fit very well on it. I can't wait to take a nap on it in a few! If you are looking for a new mattress, you can't go wrong with this one!

This mattress checks ALLL the boxes! Comfort, check. Quality, check. Affordability, check. This is THE memory form mattress for you. It's my 4th to date and wow...what a difference Serta makes. I'm mad at myself for ever choosing another brand. Ever. The quality and craftsmanship are so far above any other it's just next level. I got the CF 3000 in the medium firmness and it's just right. I feel like a Queen on my Queen mattress. I can finally look forward to a good nights sleep. My back doesn't hurt anymore and unlike my old memory foam mattress, I'm not waking up sweating and hot. Yay! The support is there and the breathability is outstanding. Serta hot this out our of the park. Molokai no further folks, this is your bed!

Wow

Submitted by katskat2 - 9/26/2019

The iComfort is the first memory foam mattress I've ever slept on. I wasn't sure what to expect. This is one of the most comfortable mattresses ever! It took me a day or two to find my comfy sleeping spot again, but once I did it was amazing. I'm a stomach,side sleeper and the iComfort just formed around my body. I had no pressure points on my knees or hip. I don't have a bad back, but occasionally it gets sore. Not once have I woken up with a sore back. Between the mattress having support and forming around your body, you can't help but have a good night of sleep. If you're worried about overheating in your sleep, don't be. I never felt over heated. I really like how the mattress just truly seemed to form around me. It really makes for well rested sleep. The hardest part is getting out of my bed in the morning, it's really that comfortable!!

Game changer!

Submitted by elarsen85 - 9/25/2019

After sleeping on the iComfort for a few nights I must say it takes a little bit to adjust to the support that this bed offers. But it supports by back like no other bed I've owed before! When you lay down you can feel the gel-memory foam start to soften and hug your body, I am a side sleeper most of the time and my lower back was always aching but I am having l no more lower back pains! One thing I will say about the memory foam is that it has quite a strong smell that you must let it air out for a couple hours prior to sleeping on. But most memory foam does have a smell to it. Overall the iComfort gave me the best support my back has ever felt and was nice a cooling at the same time, the quality is amazing and I am looking forward to the best sleep I have had in a long time!

The Most Comfrotable Sleep Ever

Submitted by xdanikitty915x - 9/23/2019

The iComfort CF3000 is the most comfortable bed I've ever had the pleasure of sleeping on . The memory foam really feels supportive with myself and my husband both having back pain , It is very comfortable to sleep on . The bed is firmer than I am use to but my previous bed was quite broken down , upon first laying down it feels firm but as you lay the memory foam really becomes softer and you become very comfortable . I know I will continue to sleep better now that I have this bed .

Submitted by Jen13 - 9/20/2019

I have been sleeping on the Serta iComfort CF3000 Medium for about a week now along with a couple of naps. I prefer a mattress that is not too soft nor too firm and this one hits the spot. I have been getting peaceful sleep along with great naps, waking refreshed and ready to conquer whatever comes my way. The only problem I have is that my dog likes this mattress as well and thinks she should have the bed to herself.
