ABSTRACT:
A folding chair includes front and back legs, a cushion frame, a cushion embedded in the cushion frame and has a hard board having air vents, a sound absorbing foam, and a back cushion connected with the inner edge of the front leg and includes a second hard board. The hard boards have curved surfaces form fitting with the human body. A securing hook has a bent hook to clasp with the cushion frame. An inserting section can make the cushion and a support block to be connecting together. The curved surfaces of the cushion and the back cushion are form fitting with the human body, and the sound absorbing foam can reduce the sound sent out from the air vents when sitting. When a child's center of gravity on the chair is shifted to the back of the cushion, the cushion does not tilt backwards.
