Has anyone found sheets that fit better than a full size bed sheet on the tipout mattress?
Good question. My solution to bottom sheet on kitchen table bed and tent bed is to give up on the idea of a fitted sheet. I like soft flannel sheets winter and summer. So I took two flat full sized flannel sheets and I sewed them together on 3 sides. then I inserted a 3 inch plush feather bed mattress cover (with no additional fabric along edges for pulling down over mattress) inside the two fitted sheets, and laid the whole thing flat on the bed. Then covered bottom sheet bag with a top sheet and blankets . wonderful cushy night's sleep.
This sounds like a great solution for a too-hard bed! I am going to try this.
