Abstract: A static chair designed to provide the user in both upright and slumped positions by the provision of different shaped layers of foam plastics material of different densities in various regions of the cushion and backrest. The cushion has a base layer of foam in which are inset two zones of lower density foam located in regions beneath the buttocks of a typical user in the upright and slumped positions respectively. The backrest is also contoured to provide lumbar support in both upright and slumped positions by the provision of foam material layers of different densities. The cushion and backrest are designed so that they may be substituted for materials in existing static chairs typically used in a theater situation without requiring total chair replacement.
