Abstract: A safety folding chair utilizes an elongated metallic plate secured at selected positions along the length of the rearmost legs having an inclined elongated slot therein with a down turned hook like end. A pin is secured extending outwardly from the rearmost marginal edge of the side wall of the seat and engages the slot. When the pin is engaged in the hook like end of the slot the rear leg cannot be inadvertently pivoted inwardly due to a force applied at the lowermost regions thereof, thereby securing the chair in an erected position providing safety to a user thereof.
