Hearth & Harbor 12" Twin Mattress in a Box, Cooling Memory Foam Mattress Twin, CertiPUR-US Certified & Odor Free

It was the second night that I slept on this mattress that impressed me. Upon arrival I was concerned that I'd misread dimensions, the mattress was folded in half and extremely compact. I'd had it on the platform maybe 10-hours before I went to bed and it was maybe 8" thick. The second night the mattress expanded to the full 10" thickness and is comfortable. --- It's my first experience with a full foam mattress so I'm sort of re-learning turning over. The mattress seems to have good support but at the same time my body kind of gullies into a position so that turning my torso over requires a bit of a lift before turning. Only time will tell if I can adapt to this change. --- I like the light weight of the mattress and the fact that I don't need a box spring. I thought I might need a board to go over my platform as the slats are further than the recommended 3" apart but it's been nearly a month and it doesn't seem to be an issue at all. ---- I do sleep well on this mattress and wake feeling good which is, to me, the most important measure for a good mattress. --- I'd buy this again and recommend it. I think it's a good value and arrived pretty quickly, too.

Shipping was fast, opened box and plastic packaging and left it to expand overnight... put it on the platform base and tried it out... I didn't wake up the next morning in pain... back pain disappeared... very comfortable mattress
