Küschall (Invacare) · Rigid-frame active / ultralight · MW-073
The Küschall Element is a limited-edition rigid wheelchair whose frame is made of natural European ash wood instead of metal tubing. It weighs about 12.9 kg with the standard back and seat cushion and 8.2 kg stripped for transport. Frame angle is 90 degrees, backrest angle 85 degrees, and seat widths run from 340 to 420 mm.
For users up to 100 kg who want a chair that is also a design object and accept a narrow range of sizes and fixed angles. It suits someone who already owns a daily chair and knows the measurements that work for them.
