Abstract
Abstract A seat for a chair includes a loop-like main frame having an upper flange wall and a lower flange wall. The main frame further includes an inner engaging edge extending radially inward and an outer flange extending radially outward. An upper perimeter face of the outer flange and an outer perimeter of the upper flange wall together define an upper coupling section to which a coupling frame is securely mounted. A rigid bottom board is securely mounted to the inner engaging edge. A mesh is mounted on top of the upper flange wall and fixed to the main frame. The mesh includes a perimeter covering the upper coupling section, with a space being delimited between the mesh and the bottom board. The seat has a reliable structure and provides cool, comfort sitting by provision of the space between the mesh and the bottom board.
