Hmm, water softener, and stool softener on the same page of the forum.

.......seen title an' thought...?..save $$......go generic......
Get some 2" foam and a yard of vinyl at a craft store, then find a memory foam bath mat (Home Depot and other places have them). Cut the foam and mat 2" wider than the stool, and staple the vinyl over for a cover. All the materials will run you about $30, but you'll have a $60 stool if you're neat about it.
