Karman S-Ergo 115 Wheelchair

The Karman S-Ergo 115 weighs only 25 lbs. making it one of the lightest folding chairs on the market today.

The S-Ergo chair has a 250-lb weight capacity and is available in 16", 18", and 20" seat widths.

Why S-Ergo:
Ergonomic seating! Not just a fancy sales term, but a functional part of this chair. The seat 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:
Fixed height desk-length arms are standard with wide concave armpads.

S-Ergo Wheels, Axles, Casters:
The S-Ergo includes 24" rear spoked polyurethane flat-free wheels with optional quick-release axles. 24" Mag wheels are optional, but are not available with the quick-release axles. Spinergy 12 spoke wheels are also an option if you're looking for a sporty machine! Front casters are 7"x1" polyurethane.

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

Front Riggings:
The S-Ergo 115 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.

Folding Frame:
The S-Ergo has a folding frame that includes a fold-down backrest. With it's optional 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.
