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.] Had it now for over two weeks. Very comfortable and relaxing to sleep on. Purchased the split cal king and works well as my husband adjusts his side very often whereas I don't. Easier than I thought to change the sheets. Going from a queen bed to cal king also made the difference. Customer service and sales person very helpful and kind.

Whatever you do stay away from this company for your mattress! They do not stand behind their products. Mattress didn't last more the. 2 years. Waste of money! You are better off buying an air mattress. They will find anyway they can not to stand behind what they sell! If I could give zero stars I would.

I told the sales person that I wanted a MEDIUM FIRM but the bed that arrived was MEDIUM ... turns out to be SOFTER than I wanted. Very nice bed but not what I waned. If there are no beds called MEDIUM FIRM then the salesman should have told me and I would have asked for a FIRM!!

I was skeptical about this mattress, but I am loving it. I am sleeping better than I have in years. Purchase and set up were very easy and quick. We did have to buy the TempurPedic sheets as our old sheets would not stay on the corners. We do love the new sheets, so it's been fine.

Fought spending the money for a bed for years. Disabled Military veteran with severe spinal problems made it something my wife insisted we go for, and I am SO glad we did. OMG, SO WORTH IT!!! I haven't slept this well for YEARS... I am lucky to have her beside me and taking such good care of me to insist on this bed, and grateful that such a quality product exists. If you are in the fence, don't delay a moment longer. It is WORTH it.

I love the TEMPUR-ProAdapt Soft! Almost purchased the medium, but am so glad I chose the "soft". I still get the support I need, but there's lots of cushion so my back wakes up feeling great and not stiff and I don't walk around for 20 minutes like I need a body cast. Purchased the adjustable base also - we elevate it just a couple of inches and now I don't hear the snoring machine next to me!!! Well worth every penny. Thank you Tempur-Pedic.

[This review was collected as part of a promotion.] I love this bed so much. I have had the rhapsody before and this firm mattress is just as comfortable, if not more! It helps me sleep so much more soundly and my back doesn't hurt when I wake. I love everything about this mattress - comfort, cooling affect, firmness, and support for my body.

[This review was collected as part of a promotion.] I had followed the recommendation of a "known consumer magazine" and bought their top rated mattress in 2019. Less than a year later, that mattress was causing me to wake up with a sore hip. This mattress took care of the sore hip!

This is our second Tempur-Pedic mattress, the first being over 11 years old and feeling a bit stiff for us. We also wanted to go from a queen to a king size bed. We tried several mattresses at the store and found this one to be very comfortable. After several weeks of sleeping on it, we both wake up without the old morning stiffness and sleep more soundly through the night.
