Abstract
Abstract The invention relates to a seat having a seat portion that is subdivided by slots to provide resilient individual supporting elements, and wherein the seat portion has a width which exceeds the span of the support for the seat portion. The seat thereby provides a maximum sitting comfort by the superior elasticity of its seat portion, the elasticity extending even into the support for the seat portion.
