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 write reviews but felt compelled to in this case! I've been to the doctor numerous times in the last 2 years for neck and back pain and taken way more prescribed anti inflammatory pills than I should at 41 years old! I didn't have a clue that my old bed was crippling me until we went on vacation and I slept in a different bed! Long story short-We INVESTED in this bed and I immediately noticed a difference after the first night. I woke up with zero pain and felt more well rested than I've seriously felt in 20 years. Not gonna lie...Dropping that kind of cash on a bed seemed kind of crazy at first and I had a little bit of buyers remorse AT FIRST!!! Knowing what I know now that was just silly!! I honestly don't think I knew what a great nights sleep actually was before! Take that money you were gonna spend on that fancy vehicle accessory or whatever else you don't really need and GET THIS BED INSTEAD!!!! SO WORTH IT!!!!

[This review was collected as part of a promotion.] Finally, a soft and supportive mattress for a bad back. Needed something better for me and also room for a cat or two (+/- a husband as well). Had our mattress 6 months now and am enjoying it immensely. Love the luxe look and feel. Love the quality as well as the adjustable frame. High price is probably the limiting factor for most. I can say this mattress has been the cats meow! Waking up pain free is a wonderful thing for this old bag of bones!

We've had our new mattress for a month now and both of us are sleeping much better with the firm mattress. Even with two full grown pitbulls, the mattress doesn't move or disturb your sleep if someone shifts their position. Both of us are getting on average 20-30 minutes of additional sleep (per watch tracking apps) than we were prior to this mattress.

My husband and I have problems sleeping like body aches and waking up during the night sweating. We decided to check out the mattress market to find a better choice for us. We decided onTempurpedic after different reviews and testing at the store. We are sorry we didn't buy sooner. GREAT PRODUCT I RECOMMEND THIS TO ALL!!

[This review was collected as part of a promotion.] First foremost, thank you TempurPedic for this free mattress in exchange for a honest review. It was a huge gamble to give up a well known old mattress to try a mattress that we hoped would suit both of our desires for firmness/softness. My husband and I are two different sizes and require two different needs for support. Being a chronic pain and orthopedic patient between the two of us, this bed was definitely up for the challenge. My husband was skeptical, but we both decided to use our FitBit sleep analysis to compare. Both of us saw an immediate change in our sleep quality, both technologically and just feeling better. I've never had a tempur pedic but my husband has, and he was most impressed with the extra layer of support the Pro-Adapt provides. I'm not only waking up with deeper rest, but I don't have the extra stiffness that a poorly supported mattress gives me. This is an excellent choice if you're in between firmness/softness desires, and the extra support (not necessarily more firm, literally support) is phenomenal. 10 out of 5 stars if possible.

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.

[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 had an original firm mattress and was worried the new tempur wouldn't live up to old one. I got the firm one and it seems comparable to my original in firmness (or very very close). Thank goodness cause I love this mattress. Not used to the chill coating but put thick mattress cover to to try and prevent cool. Still some cool but I'm ok. I love my mattress.

Was hesitant getting another foam mattress, especially one that would set us back thousands - especially since we had just had a hybrid foam/spring mattress from a different manufacturer fail on us within 5 years. We went with the brand name and reputation with this purchase and you really are getting what you paid for. We got this in a Cal King and it has been just under 30 days since we've had it delivered. The first few days were rough with our bodies adjusting to this great mattress, but now I look forward to lying down each night and feeling my body supported by the firm mattress. As soon as I get in bed and lie on my back,I feel the support where I need it and will sometimes feel my back cracking from the pressure relief of the mattress. I'm an average sized guy 5'10" and my wife is smaller framed 5'4" and we both wake up now with no pain as we had in our last bed. In true Tempur-pedic fashion, we don't feel each other get in bed since we sometimes have opposing schedules due to shift work. We sleep through the night undisturbed. We still need to get use to very little give when getting in bed for the first time each night and not feeling that initial bounce. This is a FIRM mattress and is the firmest we've found, even compared to traditional spring mattresses. Time will tell though, as the displays we've seen of this mattress in stores feel a tad softer than what we've got - but still firm.
