The two most important considerations when purchasing a bariatric commode are the dimensions and weight limit. Measure the widest part of the patient to determine the commode's needed dimensions. To measure the necessary width, use a tape measure across the back at the widest part of the patient. For the patient's weight, consider using a special bariatric scale from Vitality Medical. Patients weighing more than 500 pounds should consider a bariatric commode like the Drive Medical Deluxe Bariatric Commode that supports up to 650 pounds. For bariatric patients above 650 pounds but less than 850 pound, consider the Drive Medical Large Bariatric Drop Arm Commode.
Note: It is important not to exceed the manufacturer's weight limit for any bariatric commode chair. The next thing to consider when purchasing a bariatric commode chair is the height. If the patient has trouble lifting their body, use a bariatric commode chair with a lower height. Also, look at whether the patient has to move the commode around. If so, they may want a bariatric commode chair that weights less. Finally, look at such features as padding and aesthetics.
