A commode chair, known simply as a commode is a type of chair used by someone who needs help going to the toilet due to illness, injury or disability. A commode chair sometimes has wheels to allow easy transport to the bathroom or shower. Commode chairs placed by the bed can help if you cannot walk to the toilet. These chairs have a built-in toilet pan and are suitable for patients who can get out of bed but have limited ability to walk to the toilet.
