I bought an airmattress the other day. It was on sale. Full size for $90. Has a small motor. It is so compact it isn't funny. I have the sheet set for it. Few months back we got a twin for $90. Same company and same mtors. My room is all convertible if need be. Did a dry run the other day. Bet $50 against DH how easy it would be to turn everything back into a guest bedroom. One machine can go into the carrier, fold the other back into the desk. Room for suitcase to set on. Long table can be folded flat and put up against the wall. Ironing station can be folded and tucked into the closet. Since I have some fabric and supplies on shelves no need to move. Lots of containers can go under the work bench. Did this in under 45 minutes. I have drawers and baskets and the bench has couple cupboards. Boxes state to set up the mattresses about 10 minutes. When I need to put them back they fit just fine in the attic. My sewing room is only about 8x10.
