About Karman Healthcare
Karman Healthcare has manufactured and distributed wheelchairs and home medical equipment since 1994 from its headquarters in City of Industry, California. The company's catalog spans more than 100 models across manual, ultra-lightweight, transport, power, and bariatric wheelchairs, plus rollators, walkers, and daily-living aids, built around its patented S-ERGO S-Shape Seating System.
In our reviews, Karman's lightweight and ultra-lightweight frames stand out for the range they cover: a 13 lb aircraft-aluminum self-propelled chair for frequent travelers, a 16-inch ergonomic seat for petite users, and a sub-20 lb transport chair for caregivers loading a car trunk. That breadth, engineered under one seating patent, is why we recognize Karman among our top mobility-equipment brands.

Karman Healthcare products we rated highly
Karman LT-980 Ultra Lightweight Wheelchair
In our testing, the LT-980's 13 lb aircraft-grade aluminum frame was the lightest self-propelled wheelchair frame in the review, and its 22-inch pneumatic tires smoothed out sidewalk cracks and expansion joints that jolt smaller-wheeled chairs. The folding backrest also collapses it small enough for airline cabin storage, a feature few chairs at this weight offer.

At 13 lbs, the LT-980's frame weighs less than a third of a standard steel self-propelled wheelchair, which matters directly to anyone lifting it into a trunk. Aircraft-grade aluminum resists corrosion and metal fatigue over years of daily use, and the folding backrest is uncommon at this weight class.

Karman S-ERGO 305 Ultra Lightweight Ergonomic Wheelchair, 16-Inch Seat
The S-ERGO 305 pairs a patented S-shaped seat frame, which spreads pressure across the thighs instead of concentrating it, with a 16-inch seat width that fits petite adults and adolescents who are lost in a standard 18-inch chair. Quick-release rear wheels and flip-back armrests make it simple to break down for a car trunk or line up for a bedside transfer.

Karman K-LT-2017 Ultra Lightweight Transport Wheelchair, 17-Inch Seat
At 19 lbs with a 17-inch seat, the K-LT-2017 is built for smaller adults who need a transport chair that's easy to lift into a car. Full-length armrests give more lateral trunk support than the desk-length arms on many transport chairs, and swing-away footrests detach fully for close-in bed and car-seat transfers.
