Commodes are chairs with essentially built-in toilet facilities, providing the functions of a bathroom toilet so if you find it difficult to move around the home or get to the bathroom a commode may be just what you need.
If you are looking for something that is on wheels then the Aston Mobile Commode would be a good option. However if you want something a bit more discreet to fit in with your room then the Royal Commode looks like a piece of furniture.
