Experience freedom like never before with the Karmen S-ERGO ATX, a high-performance, ultra-lightweight wheelchair built for active users who demand precision, comfort, and agility. With its aircraft-grade aluminum frame, custom adjustability, and sleek design, the S-ERGO ATX offers the ultimate ride for those who live boldly.
Weighing just 15.4 lbs (frame only), the ATX is one of the lightest active rigid chairs in its class. Its ultra-rigid frame and compact design provide exceptional energy transfer and effortless propulsion. Whether you’re navigating tight indoor spaces or cruising the city streets, this chair responds with precision and ease.
The S-ERGO ATX is engineered for serious performance. From the multi-geometrical extruded cross bars that provide rigidity, to the adjustable rear axle plate and footplate angle, every component is designed to maximize efficiency and adaptability. The lightweight frame is robust enough for everyday use yet responsive enough for sport-style maneuvering.
Ergonomic comfort comes standard with Karman’s globally patented S-shape seating system, providing superior posture support and pressure relief. The tension-adjustable backrest and seat sling offer a personalized fit, while flip-back armrests and an adjustable footplate enhance both support and convenience during transfers.
