The mattress came like others have stated before with multiple loose threads.  The smell of the mattress is quite strong and even after 3 full days airing out before use the smell remains but not as potent.  The worst thing that I can say is that the mattress contained a tear along one seam approximately 3 inches in length.  The product looks hastily made, with that being said the mattress is the full 8 inches as advertised.  I have sewn the hole and the mattress seems to get no complaints from the teenager that uses it daily.
