5 Steps to Determine Your Wheelchair Backrest

Step 1 Determine Contour Depth.
How much lateral support is needed:
 Posterior (PA)

 Posterior Lateral (PL)

 Posterior Deep (PD)

 Posterior Deep Lateral (PDL)

 Posterior Deep Contour (PDC).

Choose from Lower Thoracic up to Shoulder Height

Each individual, depending on their functional needs and level of trunk stability, requires a different level of support.

Step 3 Determine Backrest Height

In (Step 2), the level of support is chosen. Each of these support levels are offered in
Short, Medium, and Tall.These two steps together determine backrest height.

Step 4 Determine the Backrest Width.

Measure the widest part of the trunk covered by the back or measure the chair back cane width. Reference the chart to select which width works best for the contour chosen in Step 1.

Step 5 Select Mounting Hardware 
RH hardware available on Lower Thoracic (LT) support levels.
 RH 2-point, Quick-Release hardware that is optimized for use with an ultra lightweight wheelchair, weighs 25% less than SH hardware, and offers 1.75” of depth adjustment and +/– 10° of back angle adjustment.

TH and FS hardware available on Mid Thoracic (MT), Upper Thoracic (UT), and Shoulder Height (SH) support levels.
 TH 2-point, Quick-Release hardware that is optimized for use with a tilt-in-space wheelchair, includes a lengthened bracket and attachment pin to accommodate up to 500 lbs, and offers 2.25” of depth adjustment and +/– 20° of back angle adjustment.
 FS Increased stability supports more force, 500 lb. weight capacity with hardware and over 22” wide shells.

SH hardware available on all support levels.
 SH 2-point, Quick-Release hardware that offers 2.25” of depth adjustment and +/– 20° of back angle adjustment.
