A piece of seating and supporting furniture with or without an armrest, comprising an upright and a basic seat and supporting structure (seat and structure) arranged thereon such that it can be pivoted about at least one horizontal axis, wherein the seat and structure has a seat surface which, in a first end position of pivoting about the horizontal axis, is arranged substantially in a horizontal plane, wherein the seat surface, in a second pivoting end position, is arranged transversely to the horizontal plane, wherein the seat and structure has a supporting surface arranged on a side of the seat and structure spaced apart from the seat surface. In another embodiment, a first end of a spring is connected to the upright, a second end of the spring is connected to the seat and structure, and the spring assists pivoting of the seat and structure about the horizontal axis.

The invention relates to an active dynamic seating (1) comprising a foot part (2) and a pendulum joint (10) which is rotatably mounted relative to the foot part (2), a seat (3) which is rotatably mounted relative to the foot part (2), and a pendulum column (4) supporting the seat (3), said pendulum column (4) being connected for conjoint rotation with the pendulum joint (10). The pendulum column (4) is designed to be resilient in a height direction H and the pendulum column (4) is provided with anti-rotation means (51, 52, 53) which rotationally immobilize the pendulum column (4) relative to the seat (3) such that the pendulum column (4) and the seat (3) can be rotated relative to the foot part (2) only together with the rotatable pendulum joint (10).

To realize a noble, useful seat with a simple structure designed to follow a natural movement of a seated person in front-rear and left-right directions and to support appropriately a movement of the person continuously changing its posture while the person balances a load. The seat includes the elastic support layer 3 and upper and lower base units 4 and 5 arranged to sandwich the elastic support layer 3. The upper base unit 4 includes the rolling surface 42e bulging toward the lower base unit 5 thereabove via the elastic support layer 3, is rollable in a 360° direction from the tilt reference position IRP in receiving a load of the seated person, and has a moving distal end side tilting more downward as a distance from the position IRP increases, and is configured to move while compressing the elastic support layer 3 by the rolling surface.

An adjustable-footprint suspension seat frame includes three or more feet, a first cantilever arm with a first anchor for a suspension seat, a second cantilever arm with a second anchor for the suspension seat and a first footprint adjustment bar connecting the first cantilever arm to the second cantilever arm.

The present disclosure provides a multifunctional collapsible stool including a collapsible stool body. An upper end and a lower end of the collapsible stool body include an upper seat and a lower seat respectively, the collapsible stool body includes a cavity, and an upper cover capable of opening and closing the cavity is mounted on the upper seat. A rear end of the upper seat is rotatably connected to a backup ring located between the upper seat and the upper cover. A rear end of the upper cover is rotatably connected to the rear end of the upper seat. The multifunctional collapsible stool designed this way can be utilized as a closestool or a garbage bin with the upper cover opened in addition to being utilized as a stool. Further, the multifunctional collapsible stool may also be utilized for storage. With these functions, the use requirements of more consumers can be satisfied.

Here is described a piece of furniture, and particularly a sofa, that comprises a base and a seat cushion. The base comprises longitudinal structures; a pair of transversal structures mounted to the longitudinal structures; arms rotatively mounted to the transversal structures; and poles mounted to the arms. The seat cushion is adapted to be laid over the base. The poles are movable between positions providing therethrough one of: an adjustable support for the seat cushion; and an adjustable slope for the seat cushion. The sofa may further comprise mounting brackets mounted inwardly to the frame, each one comprising a mounting rod. Cushions of the sofa comprise a cushion body; and a pair of mounting braces extending from the cushion body and comprising a slit in which the rod is positioned as the cushion is rotated around the rod until the cushion stands in place.

A double shell seat includes a base for resting on a floor, an outer shell supported by the base, and an inner shell movably supported within the outer shell. The inner shell has a seat support, a backrest support, and a hinge between the seat support and the backrest support. The inner shell is movable with respect to the outer shell from an upright condition in which the seat support has a position toward the rear of the outer shell, the backrest support has a position that is relatively vertical, and the hinge is at a first angle, to a reclined condition in which the seat support is forward of its position in the upright condition, the backrest support is less vertical than its position in the upright condition, and the hinge is open at a greater angle than the first angle. The seat is preferably free of coil springs.
