The first factor to consider when choosing a wheelchair is the size of the wheelchair. The wrong size, even the best wheelchair will not fit you. The main parts where wheelchair users bear weight are around the ischial tuberosity of the buttocks, around the femur, around the fossa and around the scapula. If the size of the wheelchair, especially the width of the seat, the height of the depth and the backrest, and the distance from the pedal to the seat cushion are not appropriate, it will affect the blood circulation of the seat where the occupant is exerting force, causing skin abrasion and even pressure sores. So the first thing we have to consider is the size of the wheelchair.
At the same time, it depends on whether the four wheels of the wheelchair can rotate flexibly, whether the material of the seat is strong and durable, whether the electroplating and coating of the frame are damaged, whether the folding is flexible and convenient, and whether the angles and dimensions of the wheelchair feel comfortable and appropriate when sitting on it.
In addition, it is also necessary to consider whether the width of the selected wheelchair matches the width of the door of your own house, otherwise it will be a big trouble if you buy it and cannot take it into the house. If the family has a car, it is also necessary to consider whether the trunk of the car can be loaded. If it is inconvenient to inflate, you can also choose solid tires. The starting point should be convenience and practicality, and comprehensive consideration.
