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.

[This review was collected as part of a promotion.] This is my second Tempur Pedic and it is just as amazing as my first! I hadn't been sleeping on a tempur Pedic for a couple years and would wake up in absolute agony. Some mornings, I would have to crawl out of bed and hobble around, my back and hips screaming with each movement. Now that I am back to a Tempur Pedic, life is so good! No more pain, just restful, deep sleep! Thank you Tempur Pedic!

So, we bought the twinxl split king. We have had the mattress now a month and its finally getting softer. It's been like sleeping on a ply-board. The first two weeks my back and joints hurt me bad when first getting up. The reclining adjustable base with LED light is nice to have at night. Love the vibrating base. Is it worth what we paid. Hard to say at this point.

[This review was collected as part of a promotion.] This is our 2nd Tempurpedic purchase. Our old mattress lasted 10 years and still has life to it. We bought the ProAdapt Hybrid medium with the adjustable base. Works silently and efficiently to cater to both our needs. Mattress is firm and supportive - bringing a high level of comfort and a good night's sleep.

I have 4 bulging discs in my back and sleeping had become so painful I'd opt to sleep on the floor or couch at times. I also sleep hot and experienced the heat of a poor quality memory foam. Since getting my ProAdapt Firm I'm finally able to sleep pain-free and get out of the bed without having to creatively "roll" out of bed. I am so in love and grateful. It was quite an investment, but it cut down on numbness and shooting pain was amazing. I did try the Pro Adapt Medium at first because I was afraid the Firm would be too stiff but boy was I wrong so I swapped it for the Firm...go with the Firm if you need the support. It will conform. It is AMAZING. If only I could afford the Tempur Breeze King-size in a Firm so I could get rid of my boyfriend's Nectar!!!!! I'd be winning everywhere.

This is my second Tempurpedic mattress - the first one I had was a Queen size Tempur cloud, medium firmness, and I replaced it with this mattress after 10 years, because I wanted a King size bed. Upon first use - the Pro-Adapt seemed softer than my Cloud was, so i was skeptical and debating if a "firm" mattress would have been a better call. However, I had been starting to get sciatica on one side, and now that I've been sleeping on this mattress for about 5 weeks the sciatica is basically gone and I haven't made any other changes to my lifestyle. I can't tell if the hybrid mattress is more firm on the sides or not, I got the hybrid after reading reviews that say Hybrid mattresses last longer than mattresses that are all memory foam. Since these mattresses come with a hefty price tag I wanted to try and get as many years out of it as I can. Also important to note, the mattress itself is really heavy, which makes tucking sheets in under the sides a little challenging, and if you live alone (like I do), I wouldn't expect to be moving it around by yourself, like if you were changing bed frames or furniture. All that said, I really like this mattress - the white glove delivery service was great, the new style of zip off mattress cover is much easier to taken off/put on than the old style, and this mattress doesn't keep me as hot as my cloud did, presumably from the cooling cover.

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.

Disappointed in your purchase? Listen up. I have a solution. I accidentally discovered if you take off the zip-ff top cover layer and sleep on the light blue mesh layer with your regular sheets/bedding the mattress will be everything that you wished it was. Cool and comfortable!! I'm not kidding. Unzip it now and try it yourself!! There is no protective layer so be cautious.

From the first night on this mattress, my sleep was totally different. I sleep through the night even though I live right next to a train track that runs all night. My cat jumps on and off the bed during the night and that doesn't disturb me anymore, either. My back is feeling better than ever. I had done a lot of research and was back-and-forth on whether to get a Tempur Pedic or Purple mattress, and I feel like I made the right choice to go with Tempur Pedic. I love everything about this mattress.

[This review was collected as part of a promotion.] This is by far the most comfortable mattress we have ever owned and we have purchased many. No more back aches or pressure points. Wake up refreshed and rested every morning. Love the cool feel, too! Would definitely purchase again and highly recommend to everyone! So happy with our Tempurpedic!
