A flat plate based system for securing legs to a chair is provided wherein a chair support has two catches and two leg pieces each have a tab at one end, the tab configured to interact with one of the two catches, each leg piece including an opening through which a tension member passes. Anchor pieces are configured to secure to the tension member such that the tension member pulls the anchor pieces together. The leg pieces each have an edge such that the edges face each other and the tabs interact with the catches and the tension member is positioned in the opening and the anchor pieces and tension member pull the edges together to hold the tabs against the two catches.

An article of furniture having a pair of side supports. The side supports are alochiral, i.e. they are the same except for hand, and each has a horizontal channel to receive slats. The channels are dimensioned to receive standard dimensioned lumber which are secured in the channels by releasable fasteners, preferably screws.

An article of furniture having a pair of side supports. The side supports are formed from panels of a sheet material having oppositely directed faces. An array of holes is formed in each panel extending between the faces and arranged as a uniform grid. Support members extend between the panels and are secured to the panels by fasteners passing through the holes and in to the ends of the support members. The placement of the support members may be adjusted to meet the configuration of furniture required with the fasteners passing through the appropriate ones of the holes in each panel.

An article of furniture includes a seat frame, first and second spaced apart seat connectors, a plurality of elongated seat panels, first and second spaced apart back post connectors, and a plurality of elongated back panels. The seat connectors and the back connectors include an upper bulbous member and a body. The panels include first and second spaced apart channels therein with cutouts extending from the channels and opening onto a surface of the seat panels. The channels of the seat panels are receivable on the upper bulbous members of the spaced apart seat connectors to form a seat, and the channels of the back panels are receivable on the front bulbous members of the spaced apart back connectors to form a back.

An joint is provided for modular furniture. The joint includes a locking tab which is held in a slot such that the tab cannot be moved out of a locking section of the slot without elastically bending the tabbed panel to prevent inadvertent disassembly of the item of furniture. The tab and slot configuration may also provide increased stiffness and rigidity to the piece of furniture while allowing the piece of furniture to be assembled without fasteners such as screws or nails.

A modular chair assembly includes a seat member and at least three support leg units. The seat unit includes a seat member which has a lower surface and an upper surface opposite to the lower surface. Each of the three support leg units is detachably mounted to the lower surface of the seat member, and includes an inner axle and a hollow tube sleeved on the inner axle. The inner axle and the hollow tube are made of different materials to permit the inner axle to have a larger anti-bending strength than the hollow tube. The inner axle includes a bottom end surface for being supported on the ground.

A chair operable between an extended configuration and a collapsed configuration includes one or more legs, a handle and a locking mechanism. The one or more legs support a seat and the handle extends away from the seat opposite the one or more legs. The locking mechanism includes a lock plug disposed in an elongate trough. Movement of the handle between the extended and collapsed configurations involves depressing the lock plug and flipping the trough to an opposite side of the lock plug.
