Kev,

I asked my wife about how she solved the sheet situation (the corners coming up) and she said that you have to look at the package. If there is no notation about the thickness of the mattress then it's for a standard 9" mattress. Ours is 15"(I think) so she just made sure it's noted on the package.

Totally forgot about the "new bed" smell until you mentioned it. Just take the sheets off during the day for a week and let the bed "out-gas"
