A folding chair includes a left central support rod, left front support rod, left rear support rod, left central leg terminal, left front leg terminal, left rear leg terminal, left limiting element, left sliding element, left limiting sliding element, left connecting element, right central support rod, right front support rod, right rear support rod, right central leg terminal, right front leg terminal, right rear leg terminal, right limiting element, right sliding element, right limiting sliding element, right connecting element, first connecting rod, second connecting rod, third connecting rod, fourth connecting rod, fifth connecting rod, sixth connecting rod, seventh connecting rod, eighth connecting rod and weight-bearing unit. The folding chair can be folded up like an umbrella and thus takes up little space and is portable and can be unfolded to demonstrate high stability and high load-bearing capability.

A chair comprising two facing and cooperating sidepieces (11), bar-type connection means to correctly and stably distance the two sidepieces (11), and, during use, a backrest (13) and a seat (12); the bar-type connection means, the backrest (13) and the seat (12) connect the two sidepieces (11) transversely in a stable manner.

The present disclosure relates to configurable stacking chairs having a standard seat base frame design to which different interchangeable seat backs can be quickly and easily attached. The seat base frames and the interchangeable seat backs may include corresponding quick-connect features that allow selective attachment therebetween. The interchangeable seat backs may be attached to a standard seat base frame via a magnetic connection. Each interchangeable seat back can have a different unique design allowing for a quick change of appearance by exchanging one interchangeable seat back design for another. The interchangeable seat backs and the standard seat base frames can be stored separately and take up less space than completely assembled or fixed back chairs.

Present invention teaches a screwless chair where the unassembled product can come in a flat package, reducing the size of storage and adding to the ease of transportation. No screws are needed for the chair of present invention; no tools are needed for the assembly/disassembly when a user unfolds the seat back from the seat base, slides the hook pieces along the groove pieces and set the seat back down by inserting the protrusion pieces to the corresponding receiving tubes; the locking tabs on the protrusion pieces provide the locking function when inserting into the receiving tubes. Errors in setting up the chair can be avoided. The ease of setting up, and thus the sturdiness and the safety of the chair, is not affected by repeated disassembly/re-assembly.

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 has a seat with a seat shell. A frame for supporting the seat has, on its side facing the seat, a mounting strut running parallel to the plane of the seat shell. An underside of the seat shell if formed with a receiving profile for the mounting strut. The receiving profile has a fastening section extending from a circumferential edge of the seat shell parallel to a plane of the seat shell into the interior of the seat shell and having an access opening at the circumferential edge of the seat shell. A clamping strip is provided for clamping the mounting strut in the fastening section. The clamping strip is slid from the access opening in a direction parallel to a longitudinal direction of the fastening section and is fixed in its end position in the fastening section perpendicular to the plane of the seat shell.
