Could you buy two Mattresses at lunch time and have them delivered by supper time!! If we were in England, you would be lucky if you got them that week!! Gotta love the USA.
I read somewhere that you should air your mattresses before putting them on the beds. You should take the plastic off and put them outside for a couple of hours. Something to do with the flame resistant chemicals. Not sure if airing them helps one little bit BUT at least my neighbours think that I am in the middle of some serious spring clean!!
