Quite firm upon delivery, outgassing quite strong nearly 3 weeks later. Though the mattress softened up nicely after about 2 weeks and is now very comfortable! I am an average temperature sleeper and live in Massachusetts, I do not feel like this mattress makes me hot at night. Overall pleased.

[This review was collected as part of a promotion.] I have slept on the Tempur pro adapt medium for 5 nights. I have never slept on a mattress like this before now. I had another brand that is basically springs and a little padding. The Tempur pro adapt forms around my body. It has the right amount of support but also the softness to be comfortable. It had been year's since I had slept through the night. Now I can say that I get a full 8 hours of sleep. My husband said its the most comfortable mattress he has ever owned. I go to bed before him and I don't even feel the movement from him getting into bed. I can actually feel a temperature difference in the new bed. It also comes with a washable cover. The only negative I have is the weight of the mattress. It definitely takes two people to move the mattress around but how often would you move a mattress around your room? Overall I am excited to have this mattress and I would recommend the Tempur pro adapt. Everyone should enjoy a restful nights sleep. We spend a good portion of our lives in bed. It should be comfortable. One more positive about this mattress. I use to have hip pain and I haven't experienced it since sleeping on this mattress. Take a chance and experience it for yourself.

Initially, we thought the bed wasn't going to be comfortable--it's so different from a normal mattress. It can feel board-stiff when you first plop down on it, but that is easy to adapt to because once you're settled in for sleep, it's seriously the most comfortable mattress we've ever slept on. Those little annoyances in a regular mattress (like feeling like you're rolling into the middle when sleeping with your spouse, or the whole dang thing jiggles when she gets up at night) are 100% gone. If you can afford it, I highly, highly recommend. The one thing I don't like about it is that it can trap some serious heat. I sleep very hot, and even with the thermostat set to 64 F, I still sometimes wake up sweating. I should have bought the cooling mattress but it's more expensive.

We've been sleeping on our new Pro Adapt Medium Hybrid for about a month now and can truly say we are enjoying our bed for once. It's nice to get up in the morning without a aching lower back or being able to sleep on your side without any pain in your shoulders. We are just hoping it will last and we can be pain free for many years to come. It's an expensive setup with the motorized frame but so far well worth it.

This mattress is very comfortable and doesn't seem to get as warm as the original which we have on another bed and bought many years ago. We got the adjustable and like being able to raise it if need too. We also got the pillows but am not as happy with them. Got the Medium and I like a firm pillow but they do not seem to give at all which cannot adjust to support my neck.

[This review was collected as part of a promotion.] SUPER comfortable and the PERFECT firmness! I'm a side sleeper, he's a back sleeper, our giant dog is an every where every way all over us sleeper and we are ALL sleeping fantastically well! Only downside is that the mattress depth makes finding properly fitting sheets difficult. Glad I picked up 2 sets from Tempur-Pedic with my promo cash. I definitely recommend getting a few sets of the sheets as well.

We are still breaking it in but I will say it is the most comfortable mattress we have ever owned. We did trade out the box springs for the smaller version because of height issues. We wished the box springs came in a small, medium, or large. We would have preferred a medium height. Still we are enjoying great sleep.

This is a replacement for an original Tempur mattress. Before purchasing this mattress we did a lot of trying other mattresses, on line research etc. Once we laid on this new Tempur we wondered why we even thought about a different brand. The adjustable base makes it even better Best sleep I've had in a year since having shoulder surgery

This is my 2nd tempur pedic. 11 years ago I bought a firm classic twin, & it was the first mattress I could sleep on that I never had any pain. For 11 years I used that mattress, & slowly saved up for a new one. I recently bought an adapt medium twin, but it was too soft & gave me pain. So I exchanged it for a firm pro adapt twin, & know that it will serve me well as did my first tempur pedic twin. I will have this one for a long time to come. Thank you for providing such a good product, especially for people with back issues. I only wish it were not so expensive.

So, we bought the twinxl split king. We have had the mattress now a month and its finally getting softer. It's been like sleeping on a ply-board. The first two weeks my back and joints hurt me bad when first getting up. The reclining adjustable base with LED light is nice to have at night. Love the vibrating base. Is it worth what we paid. Hard to say at this point.
