It stays cool for about 15 minutes. I love the comfort, but the mattress tends to get to warm. We bought this bed because some of the medications I'm on for my cancer cause night sweats and I thought it would stay cool most of the night. My best night of sleep so far was about 5 hours. Most nights it's 3 hours.

[This review was collected as part of a promotion.] Can't sleep, in fact, can't live without this mattress! It supports my back evenly and has helped me sleep a good night sleep since I got rid of my old tempurpedic mattress, which was 15 years old. Thank you for making this wonderful mattress!

I suffer from chronic back pain and fatigue from a herniated disc in my lower back. I have tried a few different mattresses in the past to relieve this pain but none helped. Most were too soft or not firm enough, I would literally toss and turn all nigh trying to get comfortable. But once I purchased my Tempur- Pro Adapt Firm mattress all my discomfort and restless nights ended. I was able to get a goodnights sleep waking up feeling rested and energetic. I'am completely satisfied with my new mattress I only wish I had gotten it sooner it has totally changed my life and my nights for the better.

[This review was collected as part of a promotion.] Several years ago, my chiropractor recommended I just try out the Tempurpedic mattress. I was having back and hip issues and needed constant adjustments. He was a happy customer and was sure this would help solve my problems. I was skeptical, but I valued his opinion. I figured I'd give it a try. I've slept on nothing since. The Tempurpedic is, beyond a doubt, the most comfortable mattress I've ever owned. I love that the mattress doesn't tell me where to sleep; I'm in charge of positioning. There are no springs intruding with their input. Further, on my old mattress, there were big indentations left by my husband's and my bodies (we're big people); no such problem with the Tempurpedic. This was my third Tempurpedic purchase; I'll not settle for anything else. As a humorous aside, my daughter supervised the delivery of my new Tempurpedic. After the team put everything together, she plopped herself on it, rolled over a few times and sighed. And Tempurpedic has a new customer!

This is my third Tempur-Pedic mattress (I'm 70). I absolutely love the support these mattresses offer. Some think you "sink in" too far, but not me. You "sink" to a degree, and then it stops, and you are supported, and then you rest. For my form, I am supported in the places that I need to be supported, and I love it!

My old Tempurpedic had started to get too soft after atleast 15 years of use. I started to have trouble sleeping with lower back pain again. I checked out some other brands but they just didn't feel right when I tested them out. The minute I tried out a new Tempurpedic I knew i had found the right mattress. It took about a week to get used to the firmness of the new mattress - the first few days felt like sleeping on plywood but after about a week my backache is gone and I'm sleeping great again. Tempurpedics are expensive but they are worth the money.

I am a younger, fit guy with no back or health problems. Had an older model Tempurpedic for over a decade. Quality was great, but it was always too soft for my liking. I went to the Tempurpedic flagship store and asked for the firmest mattress on offer. I was directed to the ProAdapt Firm, and ProAdapt Luxe Firm. The former is definitely more firm than the latter. I was told that the ProAdapt Firm that I purchased would need a period of being broken in before it would feel like the floor model that I sampled. The first couple of weeks after delivery, I was certain that I had made a mistake, as the mattress was just too firm, even for someone that likes a firm bed. However, after about 4-6 weeks of sleeping on it, it has broken in considerably and become the perfect mattress. 10/10. If you like a firm mattress, this is the one. Do not even consider returning if it feels too firm at first. Give it a month or so!

The ProAdapt Hybrid is the BEST mattress i have ever slept on. I am so happy with this purchase and have already recommended it to other friends in the market for a new mattress. My body feels hugged all night long and i wake up very rested. Highly recommend this all!

This is my third Tempur-pedic and I have to say the best one yet. The hybrid model provides the most comfortable support for my aging and damaged back. It also sleeps cooler than the Rhapsody breeze. I love the feeling of the temper foam, and the coils enhance the ability to roll over, and move easily on the mattress. I'm hooked! The pro smart base is exceptionally nice in that it provides the lumbar support and newer sleep technology. The only negative is the inexpensive feel of the remote. My Ergo base remote has motion "wake up" backlighting. The Pro Smart remote requires a flash light to see which buttons to push, before the back lighting comes on, and very quickly goes off (almost instantly.) other than the remote issue, I love my new bed!!

[This review was collected as part of a promotion.] I was on the hunt for a new mattress when Tempur-Pedic sent me this one for free in exchange for an honest review. My husband and I both prefer a soft mattress and we were excited to give this one a shot. It did not disappoint! While it seemed fairly firm at first, it relaxed over a couple of days to become super cozy while still being supportive. (It also took a couple of days to lose the factory scent, but it was never too bad and I just left the window open the first day.) When you lie down, your body slowly sinks into the foam top until you are perfectly supported. I sleep on my stomach and my husband sleeps on his back and we are both feeling fresh in the mornings. We have been sleeping on this mattress for a couple of weeks and we are pretty happy. My one gripe is that the top is very smooth and my sheets will occasionally slip right off over the corners, but it's not an issue I would deduct any stars for. Fresh sheets feel nice and crisp over the smooth surface. It's very warm out but the mattress seems to stay fairly cool. If you like a soft bed, give this one a shot!
