S-Ergo 305 Wheelchair

Folding Wheelchair

The Karman S-Ergo 305 weighs only 29 lbs., has a 250-lb weight capacity and is available in 16" and 18" seat widths. With wheels and footrest removed this chair weighs 22 lbs.

Why S-Ergo:
Karman's Ergonomic seating! The seat frame has a slight 'S" shape to it, just like the natural body's shape. See the video below for a better picture of the ergo seating. The "S" shape provides a more natural posture and discourages the sensation of sliding forward out of the seat. This feature is a big part of this chair.

S-Ergo arms:
Adjustable height desk-length, flip-back arms are standard with wide concave armpads.

S-Ergo Wheels, Axles, Casters:
The S-Ergo 305 includes 24" rear spoked polyurethane flat-free wheels with quick-release axles included. Front casters are 7"x1" polyurethane.

Frame Colors:
Available in Rose Red or Pearl Silver frame colors.

Front Riggings:
The S-Ergo 305 comes standard with removable, swingaway footrest. Footrest length is adjustable and includes flip-up composite footplates. Elevating Legrests (ELR's) are optional.

S-Ergo Seating:
As mentioned above, Ergo refers to the "S" seat shape. A more natural seated position with the legs placed just slightly higher than the buttocks. The actual seat and back includes a mesh base with a silver, anti-bacterial removable cushion system that is machine washable.

Seat Height:
There are 3 axle positions for seat-to-floor settings: 18", 19" and 20"
The quick-release axles are used to easily adjust seat height.

Folding Frame:
The S-Ergo has a folding frame that includes a fold-down backrest. With it's standard quick-release axles, the S-Ergo becomes a very compact folded chair that will fit in any automobile trunk, backseat, or simple storage in a closet.
