Description
The Karman S-Ergo 115 and S-Ergo 125 Ultra Lightweight Wheelchairs share one frame: Karman's S-shaped ergonomic seating system on a folding chair that weighs 25 lbs without footrests and carries riders up to 250 lbs. The contoured S-shaped seat is designed for comfort and stability, with breathable mesh seat and back slings, removable seat and back cushions, and a storage pouch on the backrest. Both the backrest and seat fold, and the chair folds to 12" wide. The difference is the arms. The S-Ergo 115 has fixed armrests and comes in 16", 18", or 20" seats with fixed or quick-release axles. The S-Ergo 125 adds flip-back armrests that release with a button for easier side transfers, in 16" or 18" seats. Both use 24" flat-free rear wheels with ergonomic handrims, 7" casters, and swing-in/away removable footrests, with elevating legrests available. 250 lb capacity · 25 lbs without footrests · S-shaped ergonomic seat · folding back and seat · folds to 12" · 17" seat depth · 19" seat height · 17" back · 8" arm height · S-Ergo 115: fixed arms, 16"/18"/20" seats, fixed or quick-release axles · S-Ergo 125: flip-back arms, 16"/18" seats · swing-in/away footrests or elevating legrests · 24" flat-free rear wheels with ergonomic handrims · optional 8-spoke mag wheels · 7" casters · mesh slings with removable cushions · backrest pouch · Rose Red or Pearl Silver · HCPCS K0004.

What Defines These Ergonomic Wheelchairs
S-Shaped Ergonomic Seat
Karman's contoured S-style seat is designed for comfort and stability, with breathable mesh slings and removable cushions.
25 lbs Without Footrests
A light folding frame that's easy to push and lift into a car.
Folding Back & Seat
Both fold, and the chair folds to 12" wide for the trunk or closet.
Flip-Back Arms (125)
The S-Ergo 125's armrests flip back at the push of a button for side transfers and rolling up to a table.
Flat-Free 24" Wheels
Polyurethane tires never need air, with ergonomic handrims for self-propelling.
Your Choice of Options
Elevating legrests, quick-release axles (115), mag wheels, and frog-leg caster suspension are available.
115 or 125? If the rider transfers sideways to a bed, toilet, or car seat, the S-Ergo 125's flip-back arms get out of the way. If the rider needs a 20" seat or quick-release wheels, choose the S-Ergo 115. Call us to decide: 1-866-218-0902.
