Unfold this 1/4" thick bedboard and slide it between your old, saggy mattress and box spring...your lower back will thank you! Better than a sheet of rough, heavy plywood, because you can fold it to 30"x15" for easy storage, and it won't ruin your bedding. Vinyl over thin wood board, not cardboard like many competitors. Unfolded, it's 30"x60" for a twin bed; get two for a queen size bed.See less »
