    Manuals, Literature & Videos for the A-4

    Overview of the A-4

    The Invacare A-4 wheelchair can be set up as an extremely stable wheelchair for a first-time rider, or can be adjusted easily to maximize its extraordinary handling. Its revolutionary camber inserts allow the wheelchair's camber to be changed in seconds. Its integrated headtubes are maintenance free, and its seat is available with an adjustable angle. You can experiment with the Invacare A-4's seat angle choices to find your optimum position

    Measuring Guide

    View Detailed Measurement Guide
    Seat Depth1
    Measure from the most posterior point of the body to the inside of the knee, minus at least two inches. Some prefer more leg overhang to make room for their hand when lifting their leg.
    Back Height2
    Measured from the seat base to the top of the wheelchair back. Depends on how much upper back support is needed, and also affects freedom for the upper body to rotate.
    Rear Seat to Floor3
    Measurement from the ground to the rear seat edge. Relative to the front seat-to-floor dimension, this determines the rearward slope ("dump" or "squeeze") of the wheelchair seat.
    Hanger Angle4
    Determines how far the toes extend away from the body, measured from the horizontal. A tighter angle allows the wheelchair to turn around in less space. Depends in part on ability of the knee to bend towards the perpendicular.
    Seat Width5
    Determined by the widest point of the body from knee to hip, plus an inch to ensure room to move. Consider bulk of clothing, particularly a heavy winter coat, if relevant.
    Wheel Camber6
    Angle of the wheel relative to the vertical. More camber improves stability and agility, but also limits ability to pass through narrow spaces. A typical daily wheelchair uses three degrees of camber.
    Front Seat to Floor7
    Measure the leg from the back of the knee to the sole of the foot. Then subtract the thickness of the cushion when it is compressed. Next, add a minimum of two inches for footrest clearance. Do not add the footrest clearance if the wheelchair will be foot-propelled.
    Footrest Width8
    Measure from the inside of each legrest tubing the distance or desired distance between legrests.
    Center of Gravity9
    Measure from the front of the seat back post to the center of the rear axel.
    Seat to Footrest Length10
    Measure from the edge of the seat upholstery to the top rear of the footrest.
    Backrest Angle11
    Measure the the angle of the back post to the floor. Ninety degrees will be perpendicular to the floor, to approximate the angle from the back post to the seat, subtract two degrees from measurment for every .5" of dump.
