Sitting posture, change of sitting posture and choice of a cushion are aspects which demand special attention when individuals are compelled to sit in a wheelchair. Factors which enhance comfort for able-bodied persons appear also to prevent the development of decubitus when sitting in a wheelchair. Good pressure distribution is one of the most important characteristics of a cushion. An insight is given in how a good pressure distribution can he achieved and what the effect is of different cushion characteristics and cushion systems on pressure distribution. How can a cushion be optimized for a specific individual and what is the interplay of parameters? At the same time answers to these questions produce design criteria, both for the individual wheelchair user as well as for defined user groups. Examples and results for specially developed cushions are included.
This hook is recommended to advisors of wheelchairs and wheelchair cushions, occupational therapists, physiotherapists, rehabilitation consultants, suppliers and designers of seating supports.

Dr. ir. Harry Staarink (1946) ...

gained his masters degree in 1974 at the Department of Industrial Design Engineering, Delft University of Technology. His final project involved the development of a universal wheelchair system. He continued to work on this project after his studies, the result of which was a prototype/dummy wheelchair design. In 1976 he was appointed to a staff position at the GMD where his prime area of responsibility entailed the development of assessment criteria for the functionality of wheelchairs. He was responsible for training courses on wheelchair seating to GMD wheelchair advisors. He was a member of DsO working groups on this subject. In 199 he has published `Het Zithoek, zithoudingsprohlematiek in rolstoelen' an analysis of wolf: into wheelchair seating, carried out by and for the GMD. The study on cushions and `Het Zitboek' together form the basis for this book, which was also his doctoral thesis.
The author is now a freelance researcher, designer and consultant.

Section of Physical Ergonomics ...

is part of the Department of Product and Systems Ergonomics of the Faculty of Industrial Design Engineering (Delft University of Technology). Design of consumer durables and of professional equipment is the core of teaching and research at the Faculty. The Physical Ergonomics section studies the bodily aspects of man-product interactions: anthropometrics, force exertion, motor skills etc. The aim is the collection of data on various groups of users and to make models, criteria and guidelines for product innovation.
