Foldable chair

Abstract

A foldable chair includes a foldable frame assembly movable between a folded configuration and an extended configuration. The frame assembly includes at least three scissor units. Each scissor unit is pivotally coupled to adjacent scissor units. A seat is coupled to the frame assembly. The seat has a first surface on which a user sits and an opposing second surface. A strap includes a first portion and a second portion each coupled to the second surface with respect to a first peripheral edge of the seat. The strap has a midsection between the first portion and the second portion. The midsection is operatively coupled to the seat to facilitate moving the frame assembly from the extended configuration to the folded configuration.
