[This review was collected as part of a promotion.] My previous non-split Mattress was designated as firm however, it was extremely comfortable and not as hard as this one. I do like this one, but I am thinking of switching it out for a medium firm one.

It took 5 weeks to get the bed. It's a real nice bed I haven't slept this good for a long time. The down side is that if I wake up in the middle of the night whatever part of my body is in contact with the mattress is hot and sweaty. It's no wonder why the charge a couple more thousand to get one of the cooling mattresses. Those are the reasons why i rated it a 3/5.

I had just been recovering from a GI viral infection, and had my bed up on stilts in the back to stay elevated during sleep. I was sliding down my bed and it was incredibly uncomfortable. We were looking for a great high end adjustable mattress and bed frame for our existing very nice Restoration Hardware bed frame which we absolutely did not want to switch. Not only did the ProAdapt Cal-King we bought fit perfectly, it was way more comfortable that our previous mattress and the Ergo-Extend frame that we got with it converted our bed from really very good completely awesome. Bed on stilts, and sliding down the bed at night was a thing of the past. The memory foam is really very cool during sleep - not sure how that works exactly but it seems like it has to do with the way the outside of the mattress is textured as well as the type of material used on the surface. However it works, it seems to work quite well. The fitted sheets stay in place which was a concern (with an adjustable bed) but ended up working out fine. Just completely 100% happy with how this bed. Was very worried the frames would not fit, or the quality would be less than promised, but both the mattresses and the adjustable frames were absolutely rock solid, well constructed and amazingly top notch. The only issue we had was that well known fresh "memory foam" hot out of the factory oder that the mattresses have for the first 30-40 days. They promised it would go away after a little bit.. and I can report that yes it actually did. All and all I'd say money well spent.

After sleeping on a conventional pillow top mattress it only took three nights to adjust to the tempurpedic. I love the sinking in feeling when you get into bed. It really conforms to my body and doesn't transfer any movement from my spouse to wake me up. Best decision I have made...wish I would have bought this years ago.

[This review was collected as part of a promotion.] So, at week two I was ready to leverage my free 90 day trial and return this mattress because it was not that comfortable and I was still waking up with sore joints. However, Tempurpedic customer service urged me to keep it because they said it takes at least 30 days to mold to your body and then you will feel the full benefits of the mattress. Well, they were correct because after 30 days, it felt so amazing I didn't want to get out of bed in the morning and the aches and pains of my joints certainly went away. Thanks Tempurpedic for making an incredible mattress that's helping me sleep better!

Due to my spine stenosis, initially I bought a hard mattress which worse my pain. After 30 days , choose between Medium and Soft, and I switched to a soft one and the difference is huge. Much more comfortable, seems you are sleeping almost floating . I think it will get even better. Glad I did buy a soft Temper-Pedic

[This review was collected as part of a promotion.] We had a Tepur Pedic mattress for 12 yrs and just upgraded to a king size. We tried another memory foam mattress (trying to save $$$) and ended up returning it. Once you sleep on a Tempur Pedic it's hard to switch to anything else. Originally we planned to get the soft version, but after testing out the different models in store we opted for the hybrid. We are both side sleepers and needed a "soft"mattress. For those looking for soft model I recommend testing this hybrid. It is actually very soft yet has the firmness for sitting or laying on the edge.

[This review was collected as part of a promotion.] We purchased the ProAdapt Soft and tried it for more than the recommended 30 day break-in period. The bed is very well made and you can tell it is quality the first time you lay down. We went with the soft option but it wasn't as soft as we were expecting. Our expectation is that it would be similar to a pillow top but form more to your body which wasn't the case. We opted for the return/refund which was a painless transaction. Customer service was great from beginning to end! Even though this didn't work out for my wife and I it doesn't take anything away from this great company and product. I can see now why so many people give 5 star reviews. Thank you for the great experience.

[This review was collected as part of a promotion.] I purchased online the firm Pro-Adapt and could not be happier. It is very firm and yet molds to your body and you feel well rested after sleeping on it. I know all this Nasa research and engineering went into making this mattress, but all I really know is it provides the best sleep!

[This review was collected as part of a promotion.] I was really struggling trying to justify spending so much money on a bed but it was worth every penny. Not only has my sleep improved, I'm no longer experiencing pain in my shoulders or lower back. I'm a side sleeper and this bed is an absolute life saver.
