I'm looking for a Roho shower/commode chair cushion, hoping to place it on top of my existing nuprodx6000 shower chair (the chair works well, but the seat is too firm for the boney-ness of my behind and the length of time I need to be on it). The list price is $454, and I've seen it listed for less online (http://tinyurl.com/8yfh3ww), but was wondering if anyone out there has one in good condition they'd like to sell.
