ABSTRACT:
A seat device for a chair includes at least two outer sheet layers made of a stretchable elastic textile material, and an inner sheet layer of a textile material sandwiched by the outer sheet layers. The inner sheet layer has a second marginal part surrounding substantially an entire area thereof and secured to first marginal parts of the outer sheet layers. An attachment member is associated with the first and second marginal parts and is adapted to be mounted on the chair. The entire area of the inner sheet layer is larger than that of a respective outer sheet layer so that the inner sheet layer creases when the outer sheet layers lay flat. The inner and outer sheet layers form a concaved configuration when a pressure is exerted on the inner and outer sheet layers along a direction transverse to the same.
