Photogenic Black Pullover Cushion for PG341B, PG341C

Hello, this cushion does fit over a 13 diameter stool, however, the material used around the outside has been custom fit for this manufacturers depth. The stool top has a side depth of 3 and includes a drawstring so that you may tighten the cushion in to place. I fear that if your stool does not have the same outside dimension that shifting may occur. Good luck.
