        (1) seat width: measurement of two hip or two strands sit down when the distance between the gap, in the add 5cm namely sit down on each side of 2.5cm. The seat is too narrow, the upper and lower wheelchair difficult hip and thigh tissue oppressed; the seat is too wide and is not easy to hold on, control the wheelchair is not convenient, double leg fatigue, also have difficulty entering the gate.

        (2) the seat length: between the measurement sat down after the buttocks to the gastrocnemius muscle of the horizontal distance, the measurement results will be reduced 6.5cm. If the seat is too short, the weight will fall mainly in the sciatic, easy to cause the local stress prone too much; if the seat is too long will affect the oppression of the popliteal fossa, the local blood circulation, and easy to stimulate the skin. A hip, knee flexion contracture in patients on the thigh short or, use short seat better.

        (3) the seat height: measuring sat down heel (or heel) to the popliteal space distance, plus 4cm, placed in the pedal board, board of at least 5cm from the ground. The seat is too high, the wheelchair can not enter the table; the seat is too low, then the sciatic bear the weight of too large.

        (4)cushion: in order to comfort and prevent bedsore cushion, chair sit wheelchair should put the cushion. Common seat cushion foam rubber pad (5 ~ 10cm thick) or gel pad. In order to prevent the seat settlement can be delegated a 0.6cm thick plywood in the cushion.

Low * back: sit face to the distance measuring axillary (arm or arms forward horizontally), the results can be reduced to 10cm. High * back: the actual height measuring sit face to the shoulder or post occipital.

        (6) the height of the armrest: sit down, upper arm and forearm vertical, flat on the handrail, chair surface to measure the height of the lower edge of the forearm, 2.5cm. The proper height of handrail helps to maintain the correct body posture and balance, and can make the upper limb is placed in a comfortable position.
