Had a bit of trepidation when ordering this mattress as I have never used a foam mattress before. Read reviews about a smell and not working well for certain people. 
Well,once received,it sat in it’s box for two weeks. Finally deployed it into the space in anticipation of a rapid expansion. I did not get that. Instead I got a slow expansion and absolutely zero smells. Slept amazingly well as it supported my 6’4” 190lb frame. This is a great product at an incredible price. I will purchase another whenif the need arises. WAYFAIR YOU GOT JUST WHAT I NEED!!
