The NEW ATS 500-AF chrome plated steel commode can adjust from 20" wide to 22" wide. Not only is the 500-AF commode strong, but with a welded and bolt construction it can be used over the toilet or by itself. Swing down armrests have full poly armpads that clear the seat pan to allow for easy transfers to and from wheelchairs, bed, etc. A quick release pin is used to lower armrests and will conveniently lock when the armrest is returned to the upright position. Seat height can be increased by 2" or 3" with appropriate grow kits (sold separately)
