I have an aluminum roll-out/away bed (it folds up in half and rolls out of
the way) that I need to buy a new mattress for.
I have looked in a few stores (Odd Lot, KMart) without success.

Anybody have some B&M suggestions on where I might find one of these?

The mattress is 72l x 36w x 5h. When I called a local bedding dealer
(Rockaway Bedding) they said that 72 x 36 was non-standard and I would not
find that size. They said the standard widths are typically 33 or 39
inches. I need to stop in WalMart to check.

Thanks.
