A commode chair, known in British English 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. Many commodes have legs, backrests and armrests that can be adjusted to suit your body. Some also allow you to drop down the arm rests for easy transfer. If you do get a fixed height commode, make sure it is suitable to your frame and comfortable to use.
