Connectors for assembling off-the-shelf framework such as pipes and tubes. The connectors include parts that can have puzzle-shaped ends for locking the components together, and when connected, the connectors form various cavities that may include friction-inducing components disposed in the cavities to render the framework stationary. The cavities may be sized to accommodate different sizes of framework.

A multifunctional modular furniture unit and system is developed to build a various type of furniture and housing and office accessories that are used in interior design. The multifunctional modular furniture system comprises a plurality of modular units and a plurality of support units. The modular units comprise a top block unit, a link block unit, and a bottom block unit. The support units comprise a support strap and a connection cap. The various furniture can be built utilizing attaching the modular units to each other and using the support units to reinforce a furniture structure.

A cushion and a nursing seat. The cushion comprises: a seat base (4031), and a through hole (4032) provided in a middle of the seat base (4031); a supporting structure (4033) disposed below the through hole (4032), and an accommodating space (4034) being formed between the supporting structure (4033) and the seat base (4031); and a collection box (8) detachably accommodated in the accommodating space (4034). The cushion is provided with the collection box (8) at the bottom, and may be used in the field of nursing. In addition, the collection box (8) and the cushion are detachably connected, thus facilitating handling and cleaning.

A foldable supporting device includes a linkage unit, a supporting unit and a converting unit. The supporting unit includes a main supporting member that has a first main supporting surface, and at least one auxiliary supporting member that has a first auxiliary supporting surface. The converting unit has at least one converting part that is drivable by movement of the linkage unit to convert the supporting unit between a folded state in which the first main supporting surface and the first auxiliary supporting surface cooperatively form a first angle, and an unfolded state in which the first main supporting surface and the first auxiliary supporting surface cooperatively form a second angle.

Embodiments of chair systems incorporating trekking poles include a low-back design employing fixed-length trekking poles, and a high-back design employing adjustable-length trekking poles that allow for adjusting the recline angle of the chair. The chair system generally includes a tubular frame that releasably engages a flexible seat. The tubular frame includes a front hub and a rear hub spaced one from the other by a cross bar, plus front and rear footings which stabilize the chair system on the ground or undersurface. A V-shaped upper support extending from the front hub supports and holds open the leg portion of the flexible seat, while the trekking poles are releasably engaged with and extend upwardly from the rear hub to support, and hold open and upright the back portion of the flexible seat.

A foldable chair includes a base, a plurality of retractable arms connected to the base, and a plurality of legs connected to the base. The base includes a support defining an inner cavity and a locking assembly received in the inner cavity. The support includes an upper receiving portion connected to the arms and a lower receiving portion connected to the legs. An end of each leg connected to the lower receiving portion is arranged with leg teeth. Leg teeth of the plurality of legs are engaged with each other to allow the plurality of legs to move synergistically. In this way, the user may not operate each leg respectively when unfolding or folding the foldable chair, operations performed on the foldable chair may be simplified, and the user experience may be improved.

An upholstered chair, recliner, or sofa with a frame including a pair blowmolded hollow arm rest forms, wherein frame members extend between the forms. Further components may be blowmolded such as a backrest. The arm rest forms and backrest may be reinforced with metal plates and assembled into a recliner. The connections to the arm rest forms providing a geometrically rigid and robust frame that is weighs less, is quicker to assemble, and is more robust. Upholstery sacks are easily attached to the frame.
