Abstract:

Collapsible chairs and related chair systems. An exemplary chair includes a base member comprising a seat surface configured to support a user sitting thereon, a back supporting member behind the seat surface configured to support a user's back when a user is seated, and parallel first and second side members each including first and second fulcrums. The first fulcrums connect the side members to the base member disposed therebetween. The second fulcrums connect the side members to the back supporting member disposed therebetween. The side members define a frame within which the back supporting member and the base member may be rotated about their respective fulcrums. The fulcrums allow the chair to be collapsed to a more compact configuration (e.g., for storage).
