After having a temperpedic memory foam mattress for over ten years it was time for an upgrade/change. It was delivered within a week and once unpackaged puffed up to it's full height without any issues. It is so incredibly comfortable!! It's squishy/plushy yet medium firm to ensure your back isn't sinking into the mattress. I am in love and find it hard to get out of bed in the morning cause I'm so comfy!
