I think you'd have to have a screw loose to order a mattress through the mail unless you are in an isolated area.. This is the kind of item you need to try out first. Being able to send the mattress back is not a replacement for getting the right one in the first place. When I last bought a mattress, I spent two hours testing.

This trend of selling everything online reminds of the man with a hammer who sees everything as a nail. It works well when you know exactly what you're getting, but for highly personal purchases you really need to see and feel in person to know if it is right. Some purchases are too critical to leave up to chance.

Case in point, for the first time ever I bought clothes via The Bay's website rather than going to the store. A week later I was in the store returning them. Online didn't save me any time or money.

Have fun mailing a mattress back!
