 Seat Width

To determine the seat width of the G1/G3 manual chair, please measure from the outside edge of the seat frame tube as per the picture. This is vitally important when ordering replacement upholstery panels.

 

The sequence for replacing upholstery panels is:

  1. For Seat Width – measure from outside to outside edge of chair seat frame tube. (Where upholstery panel is attached)
  2. For Seat Depth – measure existing seat upholstery panel from front edge to rear edge
  3. For Back Height – measure existing back upholstery panel from bottom edge to top edge.

 

NOTE – ENSURE CHAIR IS FOLDED OUT BY PUSHING DOWN & OUT ON THE OUTSIDE EDGE OF THE SEAT PANEL PRIOR TO MEASURING.

 Backrest Height

To determine backrest height of a G1 / G3 manual wheelchair, please measure from the top of the seat panel to the top front edge of the backrest panel as per photo 1. Please note that this will be your “effective” or clients required backrest height, not the overall panel size, as the panel extends down below the seat by approximately 2.5cm as per picture 2.
If you are replacing the backrest panel please provide the dimension as per picture 2 (overall panel height).
*Please note: Our panels are made in increments of 3cm eg. 40cm, 43cm, 46cm etc.
For backrest heights exceeding 52cm backrest extensions are required. Backrest extensions are made in increments of 10cm, up to a maximum of 40cm.
