That's why I sewed elastic diagonally across the corners rather than using sheet garters. I get on the bed on my knees and use the elastic like dental floss sliding it between the mattress and the plywood underneath it. Once the top two corners are under they can't pop out. So I can get off the bed and tuck in the bottom two corners. I then snug the whole far side under the mattress by using another elastic strap I sewed in across the middle. The bottom and open side of the bed I can finish tucking in the sheet by hand.
Oh and to keep the mattress from sliding on the plywood - two lengths of the padded shelf liner - crossways - one above the hinge and one below. It becomes a LIFT and move the mattress rather than just sliding it. I thought I'd have to staple it to the plywood, but that isn't needed.
