Definitions

  • Embodiments of the disclosure relate to a seating device. More particularly, embodiments relate to a seat member for a chair to provide comfortable seat construction having dual panels and vents on the panels for air permeability.
  • the chair seat is manufactured by combining plywood seat with foam and a fabric cushioning.
  • molded polyurethane (PU) foam is affixed on top of the plywood and the fabric is later wrapped and stapled to the plywood.
  • the plywood sheet is rigid and does not allow the air flow through it, thus increases the heat generation and makes uncomfortable for long time use.
  • plastic molded seat with foam and a fabric cushion.
  • foam instead of plywood as base an injection molded plastic seat was used.
  • the molded foam is later affixed onto the plastic seat and then the fabric was wrapped.
  • the molded plastic seat does not provide a provision to pass the air and hence heat generation increases and makes uncomfortable for use.
  • Another alternative way was carried-out by providing a spring loaded seat with metal/wooden Frame & Foam with fabric cushion.
  • a wooden seat frame was used along with a few springs in a grid pattern tied with rope and then a layer of foam is put on top.
  • the fabric upholstery is then carried-out by either nailing or stapling from the bottom side of the seat.

Further, the spring may lose its stiffness and occupant feels uncomfortable. It also requires more components thereby increases the cost of the product.
  • Chairs include a seat-back arrangement having a horizontally enlarged seat and a back projecting upwardly from a rear edge of the seat.
  • the seat often includes a cushion supported on a plastic support shell to support the occupant/user thereon.
