This mattress is amazing! Great price. The bad thing is it's so incredibly hard to wake up in the morning it feels like the perfect balance of a medium firm cloud.  It was confusing opening it up because I am used to the mattresses that immediately expand after I read the instructions it said to allow expansion for 3 days or 72 hours to be exact. I also bought mattress protectors for it and it's amazing I don't want to leave my bed.
