    Oh my - this mattress is soooo comfortable. Slept like a baby and never budged all night. It looks beautiful too- you can't see the lovely covering in the photo. I ordered THREE of these on faith from all of the reviews, and we LOVE them. I have friends who tried them out and are now ordering them for the new home they are building.

  • I don't want to get out of bed!

    This is the third mattress I've bought from Overstock, other 2 for my sons, and they loved them. Finally bought one for myself and it is INCREDIBLE - I really do hate getting out of bed in the morning. I got the 14 inch because I'm having spinal surgery soon and will have to avoid bending for some time - this is so high and just sit down and slide in. The gel phone really does keep you cool and the comfort is just beyond words. My daughter is moving out soon and I'm going to get the same mattress for her.

    I read reviews and some said the "firm" was too soft. So, I ordered firm thinking it'd be more like medium since we're both on the heavy side. Firm is more like concrete. I will say, the cool top gel must work, it doesn't get too hot.

  • The Best Quality Rollaway Bed We've Found

    We put a really big guy on this bed who was visiting for a whole week. He was comfortable. It is a good, sturdy bed and folds up easily. It is on rollers and stows away easily in a large closet. We used regular twin size sheets and we also put a twin size feather-bed on top of the mattress.

  • Best night sleep.. just turn on the A/C

    My husband and I bought this mattress right after we got married. We scoured tons of mattress reviews online before deciding on this one. We are very happy with it, but I will say for first time memory foam mattress buyers like we were, make sure you know even with the gel it is much hotter than a regular mattress. Excellent value for the price, but it will be warm! Also, if you have allergies or asthma, beware of the odor put off by the packing chemicals. Give it 5 days if possible to air out; you will be fine but may be sensitive. Overall, well worth the money!
