If your Bean Bag has gone flat or the case is stained, you can swap it out for a new one. This is just the lower bag, filler and a cap. It does not have a lazy Susan or the wooden cover plate.
Changing out the bean bag to replace the original one with depleted stuffing was extremely easy. I can’t compare it with replacing the beans only, as I’ve never done that, but I do think replacing the entire bag is preferable.
