Adam uses a commode with a soft seat (because he has a bony ass) and a splash guard. Only parents of handicapped kids know about splash guards, so don't ask. So here is how we get fleeced by manufacturers of "medical " equipment and I use the word loosely. I'll let the reader put the pieces together.
COMMODE: (steel, portable, solid stable) $40.00 US dollars
SOFT SEAT REDUCER RING WITH SLASH GUARD ( a bit of of soft rubber)
|Just the blue ring, folks, nothing else|
Adam's ring is a flashier blue!
BTW, the protrusion upward is the "splash guard"
A SUPER SOFT WALMART TOILET SEAT: $14.00
