[This review was collected as part of a promotion.] I was long overdue for a mattress update. I had been sleeping on the original Tempur-Pedic set from over 10 years ago. I must say the quality has definitely come up! I have been getting the best rest ever. I love the thickness and layers of comfort. I am a hot sleeper so I can't hold it against the mattress, but it does sleep cooler than my last set. My only complaint would be that it is hard to change my sheets now that I have to mess with a heavier mattress, but I will survive.

[This review was collected as part of a promotion.] The delivery was organized, on time and efficient. Great service. This has been the best sleep I have had in years. It's the right firmness for comfort. I have trouble staying asleep at night but since about two weeks into sleeping on this mattress, my rem and deep sleep have been better. It has even helped my husband with his snoring. My hands do not fall asleep anymore either. I'm up very early in the morning to go to the gym, and the stillness of the mattress doesn't wake my husband. Nor does it wake me when he comes to bed late at night. We got a cover for the mattress for under the sheets and it's helped prevent the cats from scratching. They seem to like it as well, and have not been tempted to scratch it.

[This review was collected as part of a promotion.] Mattress is comfy and firm,just what ya would like in a medium. Im a big guy and has good bounce from the spring feel sturdy to hold up thru the years.time will tell. I dont overheat so thats a huge plus. so far only downside is the unkown and i would have liked more foam softness on the top of the mattress to get a lil more sink in feel.

[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!

I bought this to replace a previous Tempurpedic that was 13 years old, and had lost a lot of its resilience. This one performs as well as the older one except in one regard. The cover on this one is much more slippery than my prior one, so much so that it is impossible to keep the bottom sheet tucked under it. With the slightest tension, it slides out. I have resorted to those elastic suspender things to try to hold the edges of the sheet under, but they aren't terribly effective either. Seems to me that things would be much better if the underside of the mattress cover was made out of a material that had a much higher level of friction.

I sleep very comfortably, often with mattress in the zero gravity position. I find it a bit awkward/hard getting out of bed in both the flat and z-g position, which I find odd. I love the comfort and ease when sitting up and reading. I also have an older Tempur-Pedic (when there was only one version), which I still love and use equally.

[This review was collected as part of a promotion.] From the first night sleep to almost two months later, I am sleeping the best I ever have. Most mattresses would leave me with a sore back in the morning. Also feeling sluggish and slow to start the day. With this mattress I am waking up refreshed, no back pain and feel ready to go. This is by far the best mattress I have ever owned.

[This review was collected as part of a promotion.] We had a Tempur-Pedic mattress for almost 20yrs. We started waking up with a little back pain and decided to replace the old one and purchase a new updated one. THE BEST THING WE EVER DID AND VERY GLAD WE CHOSE THE ONE WE NOW SLEEPON.

I was great at first but it softened up quite a bit that is why I have to return it. I was not expecting it to get that soft because it was a medium. I probably should have gotten a firm because for me once it softened up it just did not provide enough support.

[This review was collected as part of a promotion.] There is only one Tempur-pedic, all of the attempted knock offs don't hold a candle to this mattress. It's firm but cradles all the right places. From the moment I slept in it, my lower back pain disappeared.
