Abstract
This paper describes the design development and field testing of a novel seat concept – the two-plane seat with children with physical disabilities. A discussion highlights the potential of the two-plane seat to improve the quality of sitting posture and enhanced occupational performance in disabled children. Relevant literature on postural seating and occupational performance is presented. Design criteria and the results of design development evaluations are summarized. One pilot field evaluation involving children and their parents at home is reported. Overall, the results of this field trial illustrate the potential of the two-plane seating concept when incorporated into a bench seat with a table to influence the quality of sitting and occupational performance of children. Future research aims at evaluating this novel seating concept when incorporated in different seat surfaces. Recommendations for future research are provided.
