[This review was collected as part of a promotion.] Had pain in my side for many years knowing it was muscular. First night on the mattress and the pain is gone. Went on vacation for two weeks, pain came back. Got home back to my bed and it's gone. Not coincidental. Love this, wish I would have gotten it sooner.

[This review was collected as part of a promotion.] We previously owned a basic tempurpedic and needed an upgrade to a firmer, cooler option. This was a perfect fit for support, cooling, and relief from sciatica pain. The first night was the best sleep I have had in a very long time. If you have lower back or joint issues, definitely get this mattress.

[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!

Uncomfortable first few nights. Seem to get used to it but started experiencing lower back and hip pain. Husband with excruciating bursitis. Loss of work time. Dr and chiro appointments. Ends up sleeping in chair every night. Will probably have to return.

Replaced our 20 year King TempurPedic which we loved with the Split King adjustable because it was time for us to make the change. Hated to give up our older mattress but the newer firm split king adjustable is every bit as comfortable. The ability to alter the beds separately is a real benefit as we age. Even more comfortable than our original TempurPedic King

[This review was collected as part of a promotion.] Bed is ok, works fine, almost too firm compared to what we tested in the stores. Delivery and customer service were awful. Delivery "forgot" to put our bed on the truck the first day with little apology, more like "oh-well, not our problem." After a conversation with them explaining the difficulty in being away from work as we are both directors in our respective companies, they promise to schedule delivery for the following week, later after 4pm. 5 days later my husband is pulled away from work at because they were on their way to deliver our bed, absolutely before 4, well before 4. To make it right they offered to send us 2 pillows. Fine, I was going to purchase new pillows anyways. Although it doesn't return the significant time away from work I don't have to shop for new pillows. This was the last correspondence from them 3 weeks ago, mid-September. Since then nothing, no emails, no pillows, and no answering the phone. I sent a follow up email from my email address, my name was used to purchase the bed but contact info was for my husband so he could coordinate things, quickly received a response telling me to go to the third party I purchased from. I purchased directly through the web site. I responded with this information and my husband's information and received a very rude and short response stating they couldn't find any record of my purchase with them so they couldn't help. I've finally sent the correspondence with my husband attached to my email. Let's see what happens. I suspect more of the same- nothing.

[This review was collected as part of a promotion.] This mattress is growing on me. The first night, I woke up with a hip ache from sleeping on my side. We've had this king size mattress for about a month now, and it's getting more comfortable as time passes and we break it in. I prefer a plush-type mattress and this is what me and my partner settled on for the both of us. I have sleep issues such as insomnia, tossing and turning, waking up frequently, back problems, etc. I can't say that this mattress has improved any of the issues I have that much. My back does feel a bit better compared to my last mattress. The mattress is comfortable when you are laying down. My partner really likes it, but he doesn't really have any sleep issues. Honestly, I'm not as impressed as I thought I'd be with all the hype that Tempur-Pedic mattresses get. But I do think this is probably a great fit for some people out there. Just not sure if I'm that person since it's only been a month of sleeping on it. All in all, I do think I would recommend this to the right person. It is a nice mattress. But like I said, just not sure if it's for me, yet.

[This review was collected as part of a promotion.] We have slept on a Tempur-Pedic mattress for decades. We have found them to be firm, yet highly supportive. Quality sleep all revolves around finding the mattress that's best for you. We wouldn't choose anything else.

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.

[This review was collected as part of a promotion.] I have had a hard time finding a mattress that conforms but still is comfortable. I am 126 pounds and sleep on my side. This mattress is wonderful! It supports my body but still lets my shoulder sink in just enough so my neck and back do not hurt!
