The present invention relates to a multipurpose cushion formed from a contiguous material having a general shape of a rectangular or oblong base with a triangular portion that rises from a first end of the base toward a second end, the triangular portion covering a majority of the base portion. The cushion may be adapted for any of several uses including upright, vertical placement as an armrest and/or seat divider, or downward vertical placement as a head rest. The cushion may be adapted for applications using a horizontal placement, such as a seat cushion, a laptop device support, a foot rest, and a lumber or neck support for exercise and/or lying down activities. The cushion may further include a belt for use as a belted support in freely moving activities and exercises.

A modular furniture assembly has a modular universal base, an armrest module, and a modular recliner. The armrest is modularly coupled to one side of the modular universal base and includes an armrest member, a stepped member, a base horizontal member, and a base vertical plate. The modular recliner is coupled to another side of the modular universal base, and includes a recliner base and a backrest module. The recliner base has a plurality of frames that are interconnected and mechanically attached to each other. The recliner base includes a recessed surface that forms a transverse gap within the recliner base, and a top support having a flat top surface aligned with top edges of the plurality of frames. The backrest module has two backrest sections with end plates configured to move, respectively, along the recessed surface.

An elbow rest is configured to secure at least one of a user's elbow in a retained position while in a seated position. A user can then support their head with their hand or hands without their elbow or elbows slipping, sliding or moving. The elbow rest includes at least one support panel and a flexible strap attached thereto. In one embodiment, an elbow rest has a first and a second support panel with a flexible strap extending therebetween. In this embodiment, a person can rest their right and left elbows on the flexible strap proximal to the opposing support panels. The user can then support their head with both hands. The flexible strap may be detachably attached to the support panel to allow an adjustment of the flexible strap length between the support panels. A flexible strap may include non-slip surfaces to further prevent elbow and/or strap slippage.

A single-person chair includes a proximal end, a distal end, and a generally convex central portion extending between the proximal end and the distal end. The central portion extends upwardly, forming a first pool between the proximal end and the central portion and a second pool between the distal end and the central portion. A backrest is releasably connectable to the proximal end. A longitudinal centerline extends between the proximal end and the distal end. A first sidewall extends between the proximal end and the distal end on a first side of the longitudinal centerline and a second sidewall extends between the proximal end and the distal end on a second side of the longitudinal centerline. A liquid can be contained within the chair between the proximal end, the distal end, the first sidewall, and the second sidewall.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a chair for assembly by a user. The chair for assembly by a user may include a bracket configured to releasably couple an arm rest assembly to a chair seat and facilitate adjusting a width for the arm rest assembly relative to the chair seat.

A foldable sofa armrest and a sofa are provided. The foldable sofa armrest includes an armrest frame and an armrest skin, where the armrest skin covers an outer surface of the armrest frame; the armrest frame includes a first frame, a second frame, and a folding part; the folding part includes a first folding member, a second folding member, and a connecting component; the first folding member is provided on the first frame; the second folding member is provided on the second frame; the armrest frame has a first state and a second state; in the first state, the connecting component securely connects the first folding member to the second folding member; and in the second state, the first folding member and the second folding member are rotatable relative to each other. The sofa armrest is allowed to be in an unfolded or folded state.

A chair seat is provided for combining with two armrests. Each armrest includes a crossbar. The chair seat includes a base and two clamping devices. The base includes at least one armrest slot and two mounting holes. The armrest slot is adapted for inserting the crossbar, and the mounting hole is in communication with the armrest slot. The two clamping devices are separately installed within the two mounting holes. Each clamping device includes a mounting base, a clamping element, an operating element, and a transmission element. The mounting base is affixed within the mounting hole and features an installation slot on one side. The clamping element is installed within the installation slot, facing the crossbar. The operating element is situated on the opposite side of the installation slot relative to the mounting base. The transmission element connects the clamping element and the operating element. The operating element is suitable for driving the transmission element, which in turn moves the clamping element toward the crossbar, thereby securing it.

A chair seat combined with two armrests, each comprising crossbar with first toothed structure, is provided. Chair seat includes base and clamping devices. Base comprises armrest slot and mounting holes, where armrest slot accommodates crossbar and mounting holes are connected to armrest slot. Additionally, each of two clamping devices, installed in the two mounting holes, includes mounting base, clamping element, operating component, and transmission element. Mounting base is installed and fixed in mounting hole, with one side of mounting base having installation groove. Clamping element is installed in installation groove and has second toothed structure facing first toothed structure. Operating component is positioned on other side of mounting base relative to installation groove. Transmission element connects clamping element and operating component. Operating component is adapted to drive transmission element, causing clamping element to move towards and clamp crossbar, thus enabling second toothed structure to engage closely with first toothed structure.

A chair assembly is provided. The chair assembly includes locking members arranged at a joint between a chair chassis and a seat back support and joints between the chair chassis and two armrests correspondingly. An assembly block of the locking member is formed on the chair chassis while an assembly groove of the locking member is formed in both the seat back support and the respective armrests for being fit on the assembly block of the chair chassis correspondingly. Now a tenon disposed on the assembly block is capable of being engaged with a locking hole arranged at the assembly groove. A positioning part elastically abuts against the opposite side walls of the assembly groove. Thereby assembly of the chair chassis with both the seat back support and the armrests is finished easily and quickly. The chair assembly is more comfortable and safe for users sitting thereon.

A cover member for an elbow rest of a chair includes a mounting portion to be disposed along an upper surface of the elbow rest, and a concealing portion for covering a side portion of the elbow rest. The mounting portion is to be hooked and stopped on the elbow rest.
