Where to start? - After 72 hours only measures 10” not sure if we just got the wrong item - husband loves it - Sleeps HOT!!! - You’d think they would package it so that when you’re opening and unfolding it it would unfold with the bottom of the mattress down but no, it was bottom up. We just let it decompress and then flipped it. - Honestly not sure if we’re going to keep it as I can only sleep on it for about 1-1/2 before I wake up because of the heat.
