Firm, but doesn't cause discomfort. It is PERFECT for me. 5'5", 135 lbs, 34 yrs, female. I've never had a more comfortable bed than this. Only downside was I had to air it out for two months to get rid of that chemical smell, but I am VERY sensitive to smells. It's great now after four months of use. Contrary to popular belief, it is very supportive of activities other than sleeping. Great bed.

I never experienced such a great sleep until my wife and I slept in this bed. Seriously my back pain is gone and I would recommend Tempur Pedic to anyone and everyone.

From the very first night I had it I could tell it was going to be wonderful. I've tried other competitors mattresses and was just not satisfied. It adapts to my body and I fall asleep right away. I've had lower back issues and this mattress relieves my back pain. Best mattress I've ever had. I truly recommend it! ❤

We bought this mattress to replace a memory foam mattress that we had for almost 10 years. We've had this one almost a year and now I spend most nights on the couch. It is very uncomfortable for my husband and myself. We don't sleep well, we wake up tired and sore. We have the Proadapt soft and it is not soft at all. I'm sorry but we slept better on our cheaper mattress. I can not recommend this mattress especially at the price we paid for it. We are looking for something else to replace it.

I am not one to post reviews but I also believe to give credit where credit is due. I didn't know what to think about spending this kind of money on a mattress but I can tell you I will never own a different brand. It literally is the best sleep and has helped my sever back pain. I give it 7 stars.

I had just been recovering from a GI viral infection, and had my bed up on stilts in the back to stay elevated during sleep. I was sliding down my bed and it was incredibly uncomfortable. We were looking for a great high end adjustable mattress and bed frame for our existing very nice Restoration Hardware bed frame which we absolutely did not want to switch. Not only did the ProAdapt Cal-King we bought fit perfectly, it was way more comfortable that our previous mattress and the Ergo-Extend frame that we got with it converted our bed from really very good completely awesome. Bed on stilts, and sliding down the bed at night was a thing of the past. The memory foam is really very cool during sleep - not sure how that works exactly but it seems like it has to do with the way the outside of the mattress is textured as well as the type of material used on the surface. However it works, it seems to work quite well. The fitted sheets stay in place which was a concern (with an adjustable bed) but ended up working out fine. Just completely 100% happy with how this bed. Was very worried the frames would not fit, or the quality would be less than promised, but both the mattresses and the adjustable frames were absolutely rock solid, well constructed and amazingly top notch. The only issue we had was that well known fresh "memory foam" hot out of the factory oder that the mattresses have for the first 30-40 days. They promised it would go away after a little bit.. and I can report that yes it actually did. All and all I'd say money well spent.

I love the feel of the bed but it's too hot. I had to use a mattress pad to give me an extra layer between myself and the bed. It did change the feel of the mattress a little, it's firmer but that's ok. I'll sleep on it a few years and I'll probably get something else. I won't get a memory foam bed again.

The very first night we slept on the new bed, we couldn't believe the comfort. We don't feel each other's movements at all! I wasn't sure how I would like the "Firm," but my husband and I are happy to say we love it. Wish we had bought a Tempur-Pedic years ago!

I'm very disappointed, because the people who worked here told me that the medium hybrid would work for my height and weight as a side sleeper. I am 5"3 and 135 pounds for reference. My hips are very sore as I'm building up pressure points and I can feel the supporting layers underneath. This bed is way too firm for a side sleeper of my side. I wake up every day with a sore back sore ,sides and sore hips . I toss and turn all night long and have very bad sleep. I will say though it's not hot and it does not feel like you're on a heater or anything like that, I'm not a hot sleeper though so I'm not really sensitive to that. But that is only plus side I can think of. Unless you're a bigger person I warn you to not get this if you are a petite side sleeper, it is extremely firm and so uncomfortable.

I have had back issues from my two previous mattresses and was a little hesitant to try a soft. I am so happy that after years I'm getting a full night sleep I do not ache when I get out of bed in the morning. It's been heaven. Worth the money for sure.
