I believed the positive reviews for this item. 
￼It’s been two days since I purchased this mattress.
Unfortunately, this mattress didn’t inflate to 12 inches fully and it is not firm. It lacks the edge support. It’s very plushy almost like air bed. I guess it will do for a guestroom for now since I don’t know how to re-pack it to return it I reached out to Wayfare to complain, but I haven’t heard anything back yet. Also the corners are not straight like the advertised pictures. It does not inflate straight like that. It’s more curved and lower on the corners than the center.
