This was my first “adult bed” purchase. Let me just say, up until this point I’ve relied on family members who have outgrown their beds and up until recently it was fine. But I’m married, and sharing a full size bed with a 6’5” man is not easy! We got this in the king size and I’ll just say there’s more bed than we know to do with, so our two cats now join us in slumber every night. I am a stomach/side sleeper and sleeping in this bed on the first night was like a dream come true. The mattress does take a little while to break in, as it is a pretty firm one — back sleepers may notice this more than stomach sleepers. Since sleeping on this mattress my quality of sleep has improved by at least 10-15%. I no longer toss and turn or wake up 5-6 times a night.
