Bedside commodes can also have the pan removed and be placed over an existing toilet to provide arms to assist the person with getting up and down and they are higher than a traditional toilet.
Toilet Safety Rails
Safety rails attach to the toilet where the seat attaches. The rails make rising easier while using the existing toilet.
Toilet Riser with Handles
A toilet riser converts an exisiting toilet into a high rise. The attached handles allow the person to rise more easily.
Toilet Seat Riser
A toilet seat riser makes it easier to get up from a standard toilet. It does not require any changes to be made to the existing toilet. It is portable so it can be taken when traveling or even going to the mall since not all handicap stalls have high rise toilets.
