When you lay on the mattress you get the feeling as if you were in a sound proof room. Your movements are not free raged all over the bed. It's more like your body is absorbed where you lie, and it feels like a very slow quick sand until you fall asleep. It takes like 6 to 7 months to really soften up to your sleep positions, but is still firm enough to support your back. If you have an adjustable base it will not conform as well as the softer mattresses because it is Firm. Unless, you use the new lumbar support adjustable base by TempurPedic. Although, while laying down, it flexes some; it needs body weight. I have tried several mattresses from Sleep Number, to Purple mattresses even Hybrid mattresses and Organic mattresses. Tempur pedic is the best one, especially if you have joint pain, musculoskeletal issues and fibromyalgia this is the mattress for you. Also, if you have sensitive skin it is great since it doesn't compress the skin, is dust-mite resistant and less likely to attract bedbugs. I chose a Firm mattress, because I know over time the mattresses get softer. Also, I didn't want to have to buy another mattress for a very long time. Of course you choose one to your own comfort and needs. I do recommend you go to a Tempur Pedic store first and try the different types, do your homework before you make a selection. Remember your bed is the one place you go to release, relax and rest..choose it well. Its the one investment you won't regret!

First impression upon lying down was that it was too firm, but almost immediately we realized it was extremely comfortable. We've owned this now for 3 weeks and we have never slept better. No more backaches or shoulder aches and it is easy to get out of bed in the morning. Couldn't be happier.

I agree with so many reviewers....I used to be up and down all night with hip, leg and back pain. Now, I find the mattress supports my whole body and it almost magically has made my pain go away. Not only am I sleeping all night pain free but I also wake up pain free for the next day. I am overweight and found that other mattresses just didn't support like this one. Extra expense, yes......but you absolutely get what you pay for in this mattress!! We were told we had 30 days to decide if we liked it and my husband and I both agreed after just three nights that no one was taking this mattress from us. Love, love, love it!!!!

We have had the mattress for about 2 months now and it has definitely had a great impact on our sleep and well-being. The mattress is perfect for both back and side sleepers. The sleep I get now is way better than before and I no longer wake up with a sore back.

I waited over four years to finally buy this mattress and I am so in love with it. I will admit the first few days were not good, it took a few days to get used to the feel and I tossed and turned a bit. But now after having it for three weeks my husband and I just love it and sleep so good. Everybody asks me if it's hot and NO it's not all. We live near Sacramento and the Summers are very warm here and I think my old mattress felt so much warmer. Also I got the Pro Adapt Cooling Pillows in Mid height and I love those too. You will NOT regret buying this mattress and pillows.

It was a rough first two days on the mattress. It felt like a brick. BUT after those first two days, it molded with my body and I now sleep sooooo well! The pillows are great too. This is my second tempurpedic mattress and pillows and I can say that they have made some serious improvements to these new products. My body doesn't get so hot on it anymore either with their new pro-adapt technology. The pillows are definitely cooler and lighter. Love it! I'm very very happy with the purchase.

Having to make an exchange was definitely needed and by far our choice on this mattress has made our backs and ultimate sleep become more relaxed! No more tossing and definitely no more waking up with aches. Comfort of adjustment on our body is amazing . I wish it wasn't so heavy! Other than that you get for what you pay!

This bed is the most comfortable bed I've ever slept on. I sleep better than ever and have less pain than I have had in a long, long time. It forms to every curve right away so falling asleep is easy. It's difficult to get out of in the morning, only because it is so comfortable.

Comparable to my Celebrity bed I purchased in 2009 but doesn't have a pillow top and it's not as high. My wife and I love it though. You spend at least 1/3 of your life sleeping, spend the money and get a TEMPURPEDIC. I plan on being a customer for life. The ProbAdapt Soft is similar to a medium firmness but it's so comfortable. Also has a great warranty.

I've had this new proadapt firm mattress for 3 weeks now. The first thing I noticed is that I fall asleep so fast. When I wake up, my back feels wonderful. I've been suffering with extreme back pain for years and this mattress has been great with helping reduce it. AAA+++
