A Group 1 wheelchair is a manual wheelchair designed for users with some upper body strength and who can propel themselves using their hands. These wheelchairs are also known as "self-propelled" or "transport" wheelchairs. Group 1 wheelchairs typically have 20" wheels and weigh between 35 and 45 pounds. They are available in various sizes, widths, and heights to accommodate different users. Some models also come with features such as reclining backrests, leg rests, and tilt-in-space capabilities.
