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 is the best bed we have owned in our 45 years of marriage. Love the adjustable features. We have some aches and pains and the availability to put the bed into comfortable positions is a big plus. Our sleep patterns seems to come more quickly instead of thrashing around before settling in for the night.

We have not seen any difference yet, we're having worse back and neck pain. We were told to use it for 120 days before we could see any difference. We are using this bed over a little over 2 weeks now. The bed retains heat. So prepare to lower your thermostat. We will give another review after the time frame.

[This review was collected as part of a promotion.] My wife and I bought the pro adapt medium hybrid in a king. Our 10+ year old spring mattress was leaving me achy every morning, would wake up feeling like I got punched all night. Now those aches and pains are gone, baby! Tempur pedic so supportive it just contours your body and hugs you. Now... the down side - this mattress sleeps warm, I had no idea coming from a traditional mattress. We just put new bamboo sheets on last night and they are feeling cooler. We have a few more days to decide if we want to exchange to a luxe breeze - they are expensive but we might. Probably worth it if you're a hot sleeper, I would suggest their breeze line.

For the most part, I like the feel of the mattress. I sleep soundly, at least when I can sleep. The biggest issue is that this thing is an oven. It absorbs and holds body heat until I wake up in a boiling sweat, usually around 3:00 in the morning. If I get out of bed and let it cool down for a half hour or so, then I can make it till morning. But by then the night's sleep is ruined. This was my first memory foam, and will likely be my last.

I was hesitant buying this as a big investment and afraid it wasn't going to live up to the expectations. Background: I have substantial lower back and neck problems/chronic pain and I am a bad sleeper waking up several times a night. Do I still wake up a lot? Yes. But I do feel my sleep I do get is better, I toss and turn less and my body hurts less waking up in the morning. Not the total change I was hoping for but defenitely a huge improvements and happy with our purchase!

Slept on the mattress 3 months. It's taken a bit of work to break in the mattress. I walked on it for a total of 75 minutes per my salesperson's recommendation. My back feels great most mornings. It's a little more firm than I'd like for side sleeping.

Our previous Tempur-pedic was 20 years old plus and definitely needed to be replaced. This time we bought a split king with an adjustable base because we both need to raise our heads and my husband needs to raise his feet a little also. The ProAdapt soft mattress has proved to be very comfortable for both of us whether we sleep on our side or our back. We both have different types of back issues and I have problems with sciatic nerve so the comfort of this mattress is extremely important to us and we just love it. I can only think of one negative issue and that's it can be difficult to change the sheets.

Bed is pretty hard and then it sinks in at all pressure points and it's hard to crawl out of the holes. The sheets always pull off during the night. I always wake up with a back that is hurting and this is why I bought it to start with. I am hoping it gets better with age? Can't sit on the edge of the mattress without sliding off of it.

We had a Tempurpedic mattress in the past, after ten years decided to retire it, and to save money purchased another brand. Big mistake, I slept horribly and tried two different toppers to help, so no luck and with a sore back we had enough. Returned the toppers, it was too late for the mattress. But we went back to Tempurpedic and got this model and we LOVE it! We will never go back. No more back ache and clocking in hours of sound sleeping. Thank you!
