Large Puzzle Assembly Board with Extra Space

Bought this thinking that I could take it down and put it away while still working on a puzzle. I tested it and it doesn't work that way. I was hoping I could stand it up, vertically, with a puzzle in progress since it came with a cover. In fact, the listing information says, "" Felt lined vinyl cover allows you to cover your puzzle in progress, securing your pieces in place."" HOWEVER, the cover is not rigid and, as soon as I stood the board upright, the cover bulged out and fell off. Additionally, the pieces on the board itself do not stay in place if the board is vertical. My test puzzle pieces slid down to the end of the board as I tilted it and then fell on the floor when the cover fell off.
