This seating system has received patents from over 20 countries worldwide. By using S-Ergo series wheelchairs, users and attendants can stay away from wheelchair syndromes.

A rainy day encounter in 1987 changed the life of Kenny Chen, Karma’s founder. One rainy day in Taipei, Kenny noticed a woman struggling to fit her father’s wheelchair into the trunk of her car. The wheelchair was heavy- difficult even for a strong man like him to lift. Kenny couldn’t forget the despair of this woman, soaked in the rain and being splashed by noisy passing traffic, or the weight and the clumsiness of her father’s wheelchair. " Couldn’t wheelchairs be better?"
