The invention pertains to a jointing 2 for a furniture leg element 4, the jointing comprising: a base part 6 configured to be attached to a furniture, the base part 6 comprising a convex outer surface 8, which during use faces the leg element 4, and which outer surface 8 further comprises an elongated hole 10 defining a longitudinal extension 12 and a transversal extension 14, an elongated threaded top part 16 configured to be fixed to the leg element 4 and having a cross sectional dimension not exceeding the transversal extension 14 of the hole 10, and a sliding element 18 configured to slide along the inner side 34 of the convex outer surface 8 the base part 6 and having a threaded aperture 20 configured for cooperating with the threaded top part 16 in such a way that the leg element 4 is fixed to the base part 6 by screwing the top part 16 in the sliding element 18, and thereby enabling the leg element 4 to be fixed at a certain angle relative to the furniture. The invention also pertains to a piece of furniture comprising such a jointing 2.

A chair supporting structure comprises a base frame having a plurality of connecting arms which is downwardly inclined; a lower distal end of each connecting arm being formed with outer threads for combining with the connecting units; a plurality of legs being installed at a bottom of the a seat of a chair; an upper end of each leg being formed with an insertion hole; and a plurality of combining units for combining the base frame and let set; an upper end of the combining unit being formed with a combining hole which has inner threads; so that the outer threads of each combining arm being threadly engaged with the inner threads of the combining hole of the combining unit; a lower end of the combining unit being tightly engaged to the insertion hole so that the base frame is combined with the legs.

A system of controlling various actuators associated with human support surfaces is disclosed. Such a system is made up of a support surface, a controller, and an actuator. The system may optionally include batteries, a means of charging the batteries, and a graphical user interface as well as a communication link between the graphical user interface and the support surfaces. The actuators are capable of altering contour and/or firmness, of a support surface, they may be vibrational or heating/cooling in nature, and they may also alter the overall relative position of a support surface to another support surface, and/or to the ground plane.

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).

A height adjusting mechanism for a dentistry stool comprises a support member, a movable height adjusting assembly and a pushbutton actuator. The support member is coupleable to the stool adjacent a seat of the stool. The movable height adjusting assembly is selectively movable up and down relative to the support member. The pushbutton actuator is positionable on a side of the movable height adjusting assembly adjacent a seated user, and is manually actuatable by the seated user to release the movable height adjusting assembly from a locked position at a current height to allow the movable height adjusting assembly to be moved to a new height. The height adjusting mechanism can be implemented to provide a height-adjustable seat back and/or a height-adjustable torso bar.

A chair system may include a plurality of components that may include a seating surface having seating handles, a backrest having a backrest handle, a kickstand base, and a support frame. The configuration may generally provide a lightweight, comfortable chair system that may be easily adjusted, lifted, transported, arranged and stacked by any user, while still providing substantial structural integrity.

A specially designed seat assembly allows a user to sit in lotus style meditation position while meditating. The seat assembly positions and elevates the user in order to provide comfort while holding the user in the correct position. The seat assembly can provide dual level support through an upper platform and lower platform. The seat assembly is specially shaped in order to conform to the contours of the user. The knees are elevated by the upper platform, and the feet and ankles are drawn inward and supported from the ground by the lower platform. The user is held in a traditional lotus style seating position. The seat assembly allows for the user to remain in a relaxed state, free from discomfort. The seat assembly is supported by a metal skeleton, which prevents the seat assembly from becoming deformed upon repeated use. The seat assembly has a cushion formed around the metal skeleton, which is stable, yet comfortable for the user.

The present disclosure provides personal multimedia pods that convert from an enclosable premium theater system with seating for one or more users to an unenclosed chair and/or to an output audio/video device capable of connecting (e.g., wirelessly connecting) to other audio/visual equipment.

A chair mat including a body having a perimeter. The perimeter is defined by a rear linear portion disposed opposite an arcuate lip portion, left and right rear arcuate portions separated by the rear linear portion, a left front arcuate portion separated from the left rear arcuate portion by a left linear portion, a right front arcuate portion separated from the right rear arcuate portion by a right linear portion, a left arcuate inwardly projecting portion separating the left front arcuate portion and the arcuate lip portion, and a right arcuate inwardly projecting portion separating the right front arcuate portion and the arcuate lip portion.

A chair with a frame with tubular elements, which comprises two inverted V-shaped elements that form the front legs and rear legs, are parallel and are joined substantially at their inner curvature to a rod-like crossmember, two L-shaped elements connected by the crossmember on which they are arranged in a parallel configuration so as to form a support for the back and for the seat, respectively with first substantially vertical portions thereof and second substantially horizontal portions.
