[This review was collected as part of a promotion.] The mattress is good. It's pretty comfortable. Im a side sleeper and my shoulders and hips have issues it seems. However, the adjustable base helps some with that. I don't think the "cooling" stuff in the mattress cover does anything, especially after you put a mattress protector and a fitted sheet on top of it. Ours doesn't have much "cooling" stuff and I'm glad as I think paying more for stuff you're hiding under layers of cloth would be a waste of money. It has helped my ankles/achilles-tendons which were previously very stiff in the morning. My lower back is also doing much better with this mattress than my prior mattress. The medium firm is pretty firm still - we've only had it for a short period of time and we keep the room pretty cool - so it stays on the firmer side. My only real negative is, it's expensive!

[This review was collected as part of a promotion.] This was one of the best purchases I have ever made. For years I have contributed my back and neck issues to my job. After the first week of sleeping on the new mattress I am now realizing a lot of my issue was my old mattress!

[This review was collected as part of a promotion.] We like the hybrid feel of this mattress and the stability it provides our backs when sleeping. Its not too firm and soft enough for comfort. This is one of the better mattresses we've head in years.

I was skeptic about this mattress at first thinking I'm mostly paying for the brand but I was wrong! This mattress is amazing and so comfortable! I have not had a bad night sleep yet and I don't think I will. If you are on the fence, trust me, this mattress is worth every penny !!!

[This review was collected as part of a promotion.] After switching to this mattress I was finally able to sleep through the night and wake up without back pain again! The mattress also stays much cooler than any previous one I have owned which is perfect for sleeping through summer nights without waking up in a pool of sweat.

[This review was collected as part of a promotion.] When ordering the firmness choices were only medium and firm. Because I have lower back issues and am a side sleeper with arthritis in my shoulders, hips, I ordered the medium. After sleeping on the mattress for a few months, the mattress is still too hard for me. I do not get pressure point relief.

[This review was collected as part of a promotion.] Had a Tempur-Pedic that was 11 years old, and we loved it, but this one was so much better. Cooler and firmer, we both are getting better sleep. The only reason this is not five stars is the mattress surface is so smooth, the sheets move around and that drives us crazy. We tried three different sets of sheets and are now trying a mattress pad that seems to be working.

I love it! I use the massage feature every night to massage my bad back so I can go to sleep easily and comfortably.! The only downside for me is that it's not as tsll as my previous bed because the "raise/lower machine" is quite a bit shorter than my previous box spring. So I'm going to have my handyman build me a sort of box to set it all on so it will be as tall as my previous bed was. Problem solved!

[This review was collected as part of a promotion.] I love how this mattress conforms to my body's curves so that it is evenly supported in every position. I feel it alleviating my lower back stress as soon as I lay down on it. Relieves the daily pressure I get from standing and/or exercising. I can't wait to get into it's cozy comfort each night.

I'm a side sleeper and I move throughout the night, but I also have some back problems from some car accidents, so I needed support with some "give". This mattress has it all. A nice soft top layer to allow some room for my shoulder, but enough firmness fo give my back some much needed support. I fall asleep fast and sleep well, and look forward to naps and bedtime. Even my cat sleeps on the bed more often, and the motion transfer reducing technology means I don't get rude faces when I get up now.
