Got two twin xls with adjustable base and they fit perfectly with no gap between but allow each side to adjust. Perfect sleep and wish I bought it much sooner.

[This review was collected as part of a promotion.] Having more back and hip pain. Have only had about 4 weeks so hoping my body adjusts...My wife thinks it is very comfortable.

First two nights were ok. Weeks passed I been waking up with neck pains. And now have strain muscles in my neck not even buying the pillows help have to use to so they dont go flat.

My experience so far is this is an extremely HOT mattress. It's taking me awhile to get use to it. It's very firm for a " medium" mattress. But my biggest complaint is how hot it is.

I finally don't wake up with lower back pain everyday! This mattress is amazing for me as a back and side sleeper. So much support and yet still so soft and cozy.

As soon as I put my mattress into the Zero Gravity position my back and knee pain disappear. I sleep through the night (8 Hours) and feel absolutely no pain. I also do not toss and turn and wake up looking refreshed and well rested.

don't like it, probably is good quality but really bad for my back, after a month using it, I'm waking up with terrible back pain, feels really weird when you change positions sleeping, like a swamp, and the sheet also

[This review was collected as part of a promotion.] An automatic improvement on my old mattress, cannot go wrong with this mattress. Best sleep I've enjoyed in years, and my girlfriend loves it too. Like sleeping on clouds every night.

I'm sleeping a little bit more with it, but my wife wakes up a few times a night she says he lower back hurts, and sometimes it's the middle of her back. Maybe she still has to get use to it. It's been a month with the new bed.

[This review was collected as part of a promotion.] I fell asleep trying it out. It's supportive and comfy. It's a sleek design. I am able to get a good nights rest.
