Great mattress
I bought a Saatva that gave me horrid back pain because I’m plus-sized and a stomach sleeper. I started floor sleeping to rectify it, and I love this. I put it on a thick workout mat, and topped it with a folded mattress topper. I sleep well. Sometimes I sleep too well.

Great Pillow!
Size: King (Pack of 1)
Excellent product. I have been searching for a pillow that wasn't too soft or too hard and supported my neck. I now wake up without a stiff neck and a headache. Wonderful!
