For anyone looking for a decent mattress this isnt it.   First of all my son is good with the comfort level of this mattress, I do not like it or anything else about it.  It was late due to the snow and the directions said to unpack it within 72 hours of receiving, so I wonder if that affected the quality of it rising. It took a full 48 hours and still didnt  reach 10 inches. It has 2 pads the bottom is thick and sturdy, the top just kind of floats around on top, dangling overthe bottom on all sides by about 3 inches each. If the covering was tighter it might not be an issue, but it isnt tight and doesnt hold it all together very well.   It doesnt look like a nice mattress and when your scooting all of it with the floaty top it definitely doesnt feel like a nice new mattress.  Id just keep looking because this isnt what you want.  Hes ok with it. I just wasnt planning on this being a temporary solution to his bedding.
