We have the 10 inch twin & the 12 inch queen, a little difficult to get out of packaging but once we did it expanded quickly & no foam smell. Both beds to me were very uncomfortable, but my son thinks the 10 inch twin is very comfortable & he is very happy with that bed, but I have bad hips & I woke up in more pain in my shoulders, back & neck & I also had a hard time turning on my side. Bottom line is my son loved this mattress, I’m going to keep looking.
