Seating width: Measure the distance between two hips or two strands when seated, and then sit down on each side of the 5cm, and then each of them has a gap of 2.5cm. The seat is too narrow, the upper and lower wheelchair is more difficult hips and thigh tissue is oppressed; the seat is too wide to sit steadily, the wheelchair is inconvenient, the legs are easy to fatigue, the door is also difficult to access.

Seating length: Measure the horizontal distance between the buttocks and calf gastrocnemius after sitting, and reduce the measured results by 6.5cm. If the seat is too short, the weight will fall mainly on the sitting bones, prone to local pressure too much; if the seat is too long, it will oppress the local blood circulation and stimulate the skin of the popliteal fossa. For patients with shorter thighs or flexion contracture of hip and knee, the short seat is better.

Seat Height: measure the distance from the heel (or heels) to the popliteal fossa when you sit down, plus 4cm, at least 5cm from the floor when placing pedals. The seat is too high, the wheelchair can not enter the table;

Cushion for comfort and prevent bedsore, chair seat should be put on cushion. The common cushion has foam rubber pads (5e 10cm thick) or gel pads. To prevent seat SAG can be lowered in the cushion of a 0.6cm thick plywood.

Chair back height: the higher the chair back, the more stable, the lower the back of the chair, upper body and upper limb activities will be greater. Low chair back: measure the distance between the sitting surface and the armpit (one arm or two arms forward horizontally), reduce this result 10cm. High chair back: measure the actual height of the sitting face to the shoulder or back of the pillow.

Armrest Height: When seated, the upper arm is perpendicular, the forearm is flat on the armrest, measuring the height of the chair face to the lower edge of the forearm, plus 2.5cm. The appropriate armrest height helps maintain proper posture and balance, and allows the upper limb to be placed in a comfortable position. The armrest is too high, the upper arm is forced to lift, easy to feel tired. The handrail is too low, then needs the upper body front tilt to maintain the balance, not only is easy to fatigue, may also affect the breath.
