Background:
Many types and designs of wheelchair cushions are commercially available. Having a wide choice allows clinicians to best match a product to their client’s needs, but it also complicates the selection process.

Objectives:
The purpose of this presentation is to leave the audience with an ability to be more critical in selecting cushions that meet the needs of an individual.

Specific Aims:
To describe the different materials used in wheelchair cushion design. To define performace characteristics of cushions that impact clinical utility. To explain how standard test methods of cushions can be used to understand their clinical performance. To compare and contrast the different materials in terms of load-deflection, load redistribtion, heat and moisture dissipation, impact damping and recovery. To relate material properties to clinical situations.
