Hip Width: Use this to figure seat width if it is the widest point.
Widest Point: Measure the widest area across the lower extremities if different from the hip width. This may influence seat width or arm style.
Chest Width: Measure the widest point of the thorax just below the arm pit. This measurement may influence system width or back width.
Heel to Knee: Use this for legrest extensions and seat height.
SRP to Knee (Seat Reference Point to Knee): This will determine the seat depth.
Elbow to SRP (Elbow to Seat Reference Point): Measure this width with the arm in a 90 degree angle at the elbow and the shoulder in a neutral position.
Shoulder HeightSeat back height This will determine the height and the style of the back panel or the start for a custom back.
Head Height: This will help determine the proper headrest height.
Seat Width: Diagram #
To determine the proper seat width, measure the width of your body from hip to hip (outside hip) while seating down. Please be sure to add an extra inch or so to allow for bulky clothes if relevant.
Seat Depth: Diagram #
To determine the appropriate depth measure from the most posterior point of the body to the inside of your knee. Please be sure to remove at least 2 inches. This helps to allow for a more relaxed posture and also some individuals may prefer additional leg overhang to make room for their hand when lifting their leg.
Seat Back Height: Diagram #
This is measured from the seat base to the top of the chair back. Often users of power chairs need upper back support. Our standard medium back support works fine.
Front seat to Floor
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 chair will be foot-propelled
