The benefits experienced by assistive technology (AT) users include increased independence and comfort, however, only a small percentage of the world population with a disability has access to AT. In low income countries AT is rarely available. Sustainable methods for designing, producing and distributing AT within these are required. This paper describes the design and implementation of a seating fabrication system to be used in clinical rehabilitation settings in urban areas of low income countries. The system was implemented and tested in a collaborative project between Mexico and Colombia. More than 60 seating systems were fabricated. Therapists approved and adopted the system easily. Children and adults with disabilities were provided with a custom made seating system. Numerous additional devices would need to be developed before the AT needs of these countries are met. However, international teamwork between local universities proved to be an effective method to address the AT needs of their communities. This approach could be implemented in other low income countries.
