One of the most notable characteristics of rigid manual wheelchairs is their streamlined design. They lack hinges and folding mechanisms, resulting in a lighter and more robust structure. This design not only reduces the overall weight of the wheelchair but also minimizes the risk of mechanical failure over time. Players in the wheelchair market have innovated various designs that cater to different needs, such as adjustable seating positions, custom frame sizes, and various wheel configurations. These options allow users to find a wheelchair that best fits their lifestyles and personal preferences.
