Absolutely love my new mattress. I left it in the box until the bed platform arrived about two weeks later. I was very nervous about ordering a mattress online, considering I have never done it before. I love a comfortable memory foam mattress because springs mattresses make my body ache. I did not want anything too soft to the point that I would be sinking into the mattress when I sit down. And I did not want anything too firm that would leave me sore when I wake up. I took the mattress out the box and placed it on the platform, sat on it and thought “this is way too soft”. But once I allowed the mattress to expand for about a hour, the mattress felt absolutely PERFECT.  I usually lay on my stomach to fall asleep but usually end up waking up on my back or side. The first time I fell asleep on this mattress, I slept from 6AM until 5pm and my back feels amazing right now. You can not go wrong with purchasing this mattress.
