/diy/ - Do It Yourself

Does there exist a murphy bed solution which doesn't require wall or floor mounting? I have a full size mattress which I want to lift off the floor when not in use, murphy bed seems my ideal solution but I'm a renter and can't justify making wall/floor modifications. At worst I could just put my mattress up on its side against the wall when not in use, are there straps or something you can get to hold down sheets/comforters/pillows when the bed is up against the wall that way?
