I had a medium in this model but found it was too firm. The Pro Adapt Soft is perfect. I slept comfortably all night long the first night I slept on it. It provides support that's not too hard or too soft. Just like Goldilocks, it's just right.

[This review was collected as part of a promotion.] Very comfortable. Forget about Casper and other brands. This is my second one, first lasted more than 10 years.

When you pay this much for a mattress it should help your sleep and back pain like they advertise. It hasn't done one thing for me. Wished I had never wasted my money.

[This review was collected as part of a promotion.] Me, my wife and my 2 dogs all sleep like babies every night. When my wife or dogs move around or get up in the middle of the night, it doesn't wake me up.

We always have loved tempurpedic mattresses, this is our second one and the quality is not the same, we only had for two years and the firmness is gone, waking up with terrible lower back pain, for the price we paid not worth it.

We owned a Tempur Pedic for 22 years and just upgraded to the Pro Adapt Firm - King size mattress. All I can say is "WOW". Ultra amazing sleep and super restful mornings. Best investment for the money and results.

This is the most comfortable bed I've ever slept on. I feel like I'm sleeping in a cloud. No more aches and pains I wake up feing like I got a great night sleep.

The mattress is better than I expected. From day one - my husband and I slept through the night. When we got out of bed, we felt great - no backaches.

[This review was collected as part of a promotion.] The confort and quality is beyond my expectations. I highly recommend this mattress to those whom have back sleeping problems.

Absolutely love this mattress. I have not woken up stiff at all. It's super comfortable and soft but doesn't trap you in. I toss and turn a lot and this is great regardless of what position I sleep in.
