I have a hard time sleeping on any matress so this is just my take. Its smaller than other California King matresses. Its very firm and on the plus side you dont feel your partner move. Its extremely hot. It holds body heat real bad. I won't buy anymore temperpedic mattresses. You may like the matress but im gonna pass from now on.

I've owned my Adapt for a little less than 3 years. It is currently sitting on a support system rated to hold up under 500 pounds on each side. The mattress has gone nearly flat under weight in the mid section creating a lot of back pain for both my wife and I. We put in for a warranty claim and were turned down because we didn't have their base under it. The mattress was great while it lasted (a year before I started having issues and 2 and a half years for my wife), however, for the increased price of the mattress plus the support system required for it to not fall apart is too high in comparison to cheaper mattresses that are just as comfortable and last longer without the additional cost of a high tech support system.

I wish I had paid more attention to below 4-star reviews. I have had it over 30 days now and it not only has the suggested cover on but also 2 other mattress pads which I didn't skimp on. It does conform to your body when sleeping but rolling over is like crawling out of a hole every time you roll over. Wish I had known there was no way to return this mattress unless purchased thru Tempur-Pedic.

Excellent sleeping experience. I was having difficulty sleeping with my old foam mattress (it wasn't a Temp-P) & with the new Temp-O mattress, I sleep so much better. So far, I love this mattress & can't imagine a better one. It's the entry level mattress too.

[This review was collected as part of a promotion.] my first 2 months (or so) of sleeping on my new mattress were great. the more I used our adjustable bed, the worse of a "sink" spot right where my hips are when the bed is flat causing my back to hurt more and more. so I am disappointed with that aspect of the mattress. I thought it was just my side, but my wife's side is doing the same thing. at this price point, it should not be doing this.

After our dealer finally delivered the right bed, I personally love it, more nights of restful sleep for me. My husband apparently is never getting a restful nights sleep. This mattress is not cooling by any stretch of the imagine.... I mean unless you sleep on only the mattress. But you see here's the kicker. You have a warranty for this bed, as long as there are no stains etc. So you are forced into buying a cover, which keeps you from potentially staining the mattress but probably obscures the "cooling" feature of said mattress. I'm purely guessing here, but I would think my husband profuse sweating would qualify as a stain which would render the warranty void according to our dealer. So if this mattress really is cooling we would never know. Same goes for these awful "cooling" pillows, they do not work either. They didn't offer pillow covers, so I am sure they are no longer under warranty. Idk its an awful lot of money to spend on the possibilty of a cooling good nights sleep. Not sure I could recommend this to everyone, especially to those without a diagnosed reason for hot sleeping with sweating. Yet I'm happy with this mattress and so is my back, which I have a herniated disc and degenerative disc disease and I usually wake up pretty refreshed and feeling well with my back!

I have experienced relief from my lower back pain since sleeping on our new Tempur Adapt Medium king mattress. We have had the mattress for six months now and it has not developed any "body impressions," unlike previous mattresses we have owned. We would recommend it to others.

We have not found it to be comfortable or provide any cooling as sales rep assured us it would be. We bought the special mattress cover and sheets and I am hotter than I was with our previous bed and definitely not as comfortable. It has been 20days & not any different than day 1. We will give it until 30 days and then exchange it for something else.

I absolutely love this bed! It's the perfect firmness with some give (got a medium). Melts to my body and gives me the best sleep I've had in very long time. I don't notice when my dog moves about or jumps on the bed. I'm so thankful for this bed for I have a very physically demanding job with long hours. My quality of sleep has improved drastically. Thank you!

My wife and I both love the spring support coupled with the pressure relief and movement dampening properties of the Tempur material. We have both gotten a higher quality of sleep since we've had this mattress. It's so wonderful to not feel every little movement and wake up without lower back pain.
