Abstract
A collapsible chair has a pair of front legs, a pair of rear legs, a pair of back support rods, a seat, and a cross brace that slidably couples one of the back support rods to one end of the cross brace and one of the front legs. The legs, support rods and cross brace are coupled such that the chair collapses in a single movement in which the front legs approximate each other when the seat pivots towards the back support rods.

A collapsible chair, comprising:
- a pair of front legs, a pair of rear legs, a pair of back support rods, a seat having a first side and a second side, and a cross brace with a first and second end, the first end coupled to one of the rear legs, and the second end slidably coupled to one of the back support rods via a coupling element;
- wherein the coupling element further slidably couples one of the front legs to the one of the back support rods;
- wherein the first and second sides of the seat are coupled along at least part of their length to the pair of rear legs, respectively, such that the seat is supported between the rear legs;
- and
- wherein the front legs, the rear legs, the cross brace, and the back support rods are coupled in a manner such that the chair collapses in a single movement in which the front legs approximate each other when the seat pivots towards the back support rods.
