Abstract: A first folding chair may include a connector device configured to releasably connect to a second folding chair. The connector device may include two connectors coupled to each other, where the first connector is configured to be attached to the first folding chair and the second connector is configured to be attached to the second folding chair. Each of the first and second connectors may be any of a loop, a hook, a strap, a ring, or a combination thereof. When the first folding chair and the second folding chair are connected by the connector device, the first folding chair functions as a lead chair and is configured to be strapped to a user or carried by the user while bearing weight of the second folding chair. In such manner, multiple folding chairs may be connected to form a stackable multi-chair system.
