This is a great futon. Does come with a little of that chemical smell but if you let it air out as suggested it inflates to about 10 or so inches (I didn't expect the full 12 anyway). I am a bigger guy and wanted to try sleeping on this thing right away. After the first and the second night I was having some back pain due to the overall mattress being a little stiff for my personal liking. To fix the problem I ordered a queen pillow topper and then a black futon cover to return it to the color I wanted it in. Absolutely no problems now. Sleeping on it is like a dream. I would definitely suggest this product to people shopping for a good solid queen sized futon mattress 

Pros: Nice an thick. Good quality probably leading to go durability
Cons: Chemical smell. A bit to stiff for my liking. (though easily correctable)
