The mattress felt very firm from the start. It is not softening nearly as much as I want - it's still not like the showroom mattress or the two different soft tempur pedic mattresses I've slept on in the past. I'm 3 1/2 weeks in to the 'break in' period and I hope it improves soon. I'm disappointed - I was really looking forward to a great experience.

[This review was collected as part of a promotion.] I had a cheap bed for years and woke up nearly every morning with lower back pain. Finally splurged on a Temper-Pedic mattress, and not only do I love how comfortable it is, my back pain went away and hasn't come back. I'm very glad I bought this mattress.

It's fine to sit on or just to relax on. When I go to bed to sleep I find myself miserable. Tossing and turning. If I sleep on my back my neck will hurt, if I sleep on my side my knees and elbows hurt. I got an adjustable base. If I try to sleep at different angles with that it just doesn't help. I've had it for a short time but still have not found a comfortable position to sleep on it yet. I have a lot of different pillows to try with it too and I just can't seem to make this mattress work for me. :( We bought a split king. My husband seems to enjoy it and definitely seems to toss way less then I do.

Our new mattress is wonderful! I love that I am not affected by my husband's movement during the night. The temperature is always comfortable and I don't get overheated like I did with our old mattress. I sleep through the night and wake up feeling refreshed and not achy!

[This review was collected as part of a promotion.] We bought this mattress after buying many cheaper mattresses. We have always hesitated on Tempurpedic due to price, however we are so glad we decided to go ahead and get it because you get what you pay for and we now have the BEST BED EVER! So dont hesitate, just do it, and get pillows, sheets, and adjustable bed too... Its like sleeping in Heaven!!

This is our second set of Tempur-pedic spit king mattresses. They have been great. Our first set developed a dip in the middle after 9 1/2 years. I contacted the company and they made good on their warranty with no problems. I have recommended their product to several people. We have Tempur-pedic split king beds in two locations and we sleep great in both.

I toss and turn a lot on this mattress and if I sleep over 6 hours, I wake up with pain in my middle to lower back. I am 6'2" and weight between 195-200-ish. I have been to both my family practitioner and a chiropractor to confirm that I do not have any back issues, injuries or circumstances that would cause me back pain. I travel for work and will sleep on a hotel mattress at least a couple times a month and usually sleep like a baby with out tossing and turning and with out back pain. My wife also did not like her bed and ask that I put her Next Alexander Hybrid back on her side. I will probably go with a Sealy Posturepedic . I bought them for my 11 and 16 year old and they love them.

It was nice and plush the first few months. Now it has turned into a brick. I get pain in my heels just laying on my back for 5 minutes. It is ridiculous how bad the pressure point relief is. The worst mattress I've ever used. I get horrible sleep, aches all over no matter the position. And now it has started the flake a white snow when I change the sheets and mattress cover. Probably not good to be inhaling white mattress flakes while I sleep. I would give it zero stars if I could. Do not be lulled in by the initial comfort that will wear out just after the return period ends. What a waste of money.

[This review was collected as part of a promotion.] Great product, although the foam seems to hold body heat a bit more than our old conventional mattress. Would have gone with the gel version, but they didn't have it in firm. The "white glove" delivery service leaves a lot to be desired -- couple of guys and a truck -- took all three of us get it off-loaded and up the stairs. They clearly didn't know anything about the frame and set up.

The 1st night slept great-much more support than our 3-year old Cloud Supreme (a soft-medium mattress), The next few weeks were not as great, had traded in my neck pain for shoulder pain. Switched to a higher and firmer Bamboo pillow and that has surely helped. Wife has found new mattress better for her lower back. Overall, an improvement, Verdict is still out whether we will keep it or switch to the medium ProAdapt model.
