The proper fitting of a wheelchair is essential for a number of reasons: 

• Comfort: A well-fitted wheelchair will provide a comfortable seating experience, helping to prevent pressure sores, back pain, and other discomforts. 
• Functionality: An ill-fitting wheelchair can interfere with the user’s ability to perform daily activities, such as reaching for items, propelling the chair, or getting in and out of the chair. 
• Safety: A poorly fitting wheelchair can put the user at risk for falls or injuries, such as tipping over or sliding out of the chair. 
• Health: A correctly fitted wheelchair can help to maintain proper posture, reduce the risk of injury, and promote overall health and well-being. 
• Independence: A well-fitted wheelchair can help to improve the user’s independence and ability to participate in daily activities. 

Therefore, it is important to work with a professional to select the right wheelchair and ensure a proper fit. This may involve measurements, trial periods, and adjusting the chair as needed.
