Rick Goldstein is a c5-6 quad and invented a portable commode/shower-chair, called Go! Mobility Solutions, because he was never able to find one anywhere and was never able to travel. It is light and fits into a suitcase. The Go! Mobility Solutions Portable Commode/Shower-Chair can expand to go over a bath tub lip as shown in the below photo or can sit as a regular shower-chair and used as a commode.
