Coming out of the box it is lumpy, but after only a few hours you can see how well it fills out. Does have a plastic odor, compared to the smell of a sharpie, but seems short lived. My daughter is 5ft 8in, and the picture is taken right after unboxing, so still not to full fuf capacity.  Highly recommend!!!  My son is 6ft 5in and lays comfortably on it too. Picture is next to a full size bed on standard frame with box springs to show height, but again not at 7-10 day fullness as instructions suggest.
