Had to order new foam mattresses for our twin bed '69 and the dimensions were 76" X 32" so regular twin sheets wouldn't work. I am sewing pleats where needed on the regular "on sale" twin sheets and it's working great. The made to order trailer sheets are so expensive, and we are pinching pennies wherever we can. Moisheh if you need to order foam for your gaucho, beds, etc. "Knox Foam" is great! They offer numerous grades and will custom cut any size needed. Reasonably priced too!
