Overview of the Lightweight S-Ergo 115/125

The Lightweight S-Ergo 115 and 125 from Karman Healthcare has a specialized frame that reduces pressure and is available in 16", 18" and 20" seat widths. It has swing-away footrests standard with elevating legrests as an optional upgrade and "tube-in center" footplate that assures better side leg support. The backrest easily folds for transportation and storage and it also features a pouch for carrying small items. A 1/4" thick silver colored anti-bacterial cushion is standard, it is odor and stain resistant and is machine washable.
The S-Ergo 115 has fixed armrests and the S-Ergo 125 has flip-back armrests.

Measuring 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 outside of right hip to outside of left 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.
