We got this California King sized mattress to replace a waterbed insert mattress that we had kept way past its expiration date! We expected an initial adjustment period. But from the 1st night, it felt great! It fit perfectly inside our waterbed frame, and was the perfect thickness to let us roll out of bed without landing on the hard sideboards of that frame. The only negative thing I can think to say about this mattress is that the "Law Tag" was nowhere I could find. And the website was of absolutely no help in pointing me to the right spot to look for it. That tag has the serial number of the mattress that the online registration process requires. I ended up calling customer support, and they registered my mattress without that S/N. Still, it would be helpful if the online registration function, knowing which mattress you are trying to register, could direct you to EXACTLY where the tag could be found. Another way to be helpful about this would be to encourage retail store delivery staff to show customers this tag so the S/N could be recorded BEFORE this heavy mattress gets put in its "final resting place". P.S. I'm not writing this review because it qualifies me for entry into a monthly prize drawing (Big deal ... I never win anything ;-) I'm writing it, hoping that someone will actually fix the online website as suggested above. While it is no longer an issue for me, it will continue to needlessly frustrate future customers. You're welcome!

[This review was collected as part of a promotion.] I've struggled with hip and knee pain for a decade now. I finally bit the bullet and invested in the best mattress I could find. This is by far the best sleep I've had in 15 years. I wake up in the exact position I fell asleep in and wake up feeling rejuvenated and incredible in the mornings. Best money I have ever spent on myself.

[This review was collected as part of a promotion.] I bought this for my parent's and they were skeptics that this mattress couldn't possibly be different from any other mattress on the market. When the mattress arrived after the first night, they raved about how the mattress helped them sleep better, their backs were no longer aching and also that the mattress was so great that they didn't want to get up in the morning for work. Thank you tempur pedic for coming through !!!!

[This review was collected as part of a promotion.] I've had the original Tempurpedic bed, which I really like, for over 12 years, so when it was time for something new, I upgraded to the Medium Hybrid. I thought I great bed before, but the new one is so good it's beyond words. This sleeps cooler, is firmer around the edges, and is just fantastic all around. It is almost indescribable how comfortable this bed is. It's almost like sleeping on air. It is truly amazing. I've tried to think of something I don't like about it but really can't find anything. I love this bed more than I can put in words.

I'm a 130 lb side sleeper and my partner is a 185 lb side sleeper. The mattress was very firm when it arrived. After sleeping on it about 2 weeks, it softened to the point where we just sunk down into it. No support. Horrible back pain. We gave it 5 weeks total but eventually returned it to the store.

I got this bed to get an update from my Tempurpedic rhapsody. It offers similar comfort, but the medium-hybrid is a bid softer. This is the best sleep I've gotten, ever. I hope this holds up as well as my last bed as It's still being used in my guest room.

We were many years overdue tossing out our original king size mattress and box spring. After visiting our local mattress store, and laying down on 6 or 7 mattresses, this is the one we knew we had to have, and since, we have experienced solid nights of sleep, and every little ache and pain we had has vanished. The price was worth it!

[This review was collected as part of a promotion.] On my new firm tempurpedic mattress I've had he best sleep I've had in years. I sleep through the night, and feel supported at every point. It's been especially helpful because of a recent back injury. I can't think of any drawbacks honestly. It's expensive, but good sleep is worth it. We spend 1/3 of our lives sleeping, so it's worth the investment in yourself. I wake up more refreshed and energized than i have in years of sleeping on my old mattress.

This is the most comfortable mattress I have ever slept on. I wake up far fewer times at night, which I believe is a health benefit. I had one of the original Tempur-Pedic mattress for over 20 years, and wanted to upgrade. When I laid on the Pro Adapt mattresses in the store, it didn't necessarily feel like supreme comfort. I knew from experience that at first, a Tempur-Pedic mattress feels a little firmer than other mattresses. I was confident the Pro Adapt would be at least as good as my first Tempur-Pedic. Having now used it for the month at home, I cannot believe the level of comfort.

At first, the mattress felt too firm but as I started to get used to it and break it in I am starting to have a better night's sleep. I have noticed that I do not toss and turn nearly as much sleeping on this mattress compared to my prior mattress that needed to be swapped out under warranty. I am so glad I paid for the upgrade on this mattress. I will say also this mattress is a lot cooler than the Tempurpedic mattress I owned in the past. I will say when it arrived it felt too firm but just sleep on it and it will break in just fine. I will say that it is relatively a thick mattress I needed new sheets as they kept coming undone. So just buy deeper pocket sheets especially if you have an adjustable base like I do that I also purchased.
