Disclosed herein is a dynamic pendula stool possessing a foot, a leg secured to the foot, and a seat secured to the top end of the leg. The leg has a telescopic column that includes a lower part secured to a spherical foot with a diameter of 20-cm or less and an upper part with a free end having an articulation. The articulation has three degrees of freedom and is secured to the underside of the seat so that when a user rests against the seat, the leg forms an angle between 30 and 90 degrees with respect to the horizontal, thereby allowing an isometric contraction of the muscle groups of the lower limbs and of the abdominal girdle in the seated position. The stool is further provided with one or more sensors configured to send data signals to a remote electronic device.

A seat, particularly for playing video games, includes a tubular frame, a seat surface and a backrest. The seat surface and the backrest are formed by a piece of cloth tensioned in the frame, and the frame includes two lower frame parts extending forward from the backrest and each having a curved progression which is convex in downward direction. Each lower frame part can have a front outer end and a rear outer end, and the two lower frame parts can be connected to each other close to their front outer ends and close to their rear outer ends by front and rear transverse frame parts, which can each have a curved progression which is convex in upward direction. A tubular frame and a cloth are configured for application in such a seat.

A reclinable director chair having a chair cloth, a seat frame assembly and a support frame assembly. The seat frame assembly having two cross tubes, two square seat frame armrest tubes and two backrest support tubes, wherein the cross tubes are connected and fixed between the two seat frame armrest tubes in a cross manner. One backrest support tube is disposed at the rear end of each seat frame armrest tube, and a cushion and a backrest of the chair cloth are mounted at upper ends of the cross tubes and on the backrest support tubes, respectively. The support frame assembly having two support frame components. Each support frame component comprises a bottom support tube and a connector.

A chair facilitates both rocking and bouncing. The chair includes a base adapted to support a seating portion, the seating portion having a surface adapted to be sat on by a user. The seating portion has a bouncing mechanism, such as an exercise ball. A rocking mechanism is provided to cause the base to rock. The rocking mechanism facilitates the rocking back and forth of the user when the user is seated on the seating portion, and the bouncing mechanism facilitates the bouncing of the user when the user is seated on the seating portion. The bouncing is in a bouncing direction that is different than the direction of rocking. The chair is particularly useful for calming a baby and/or for facilitating stimming.

A linkage for use in reclining furniture may include a back bracket supported by forward and rear back pivot links. The bottom of the rear back pivot link may be pivotably coupled to a rear lift link and the bottom of the forward back pivot link may be pivotably coupled to the rear lift link in a different location. A control link may be pivotably coupled on one end to one of the forward back pivot link and the rear back pivot link. The control link may pull the pivoting linkage of the back bracket and the forward and back pivot links as the overall linkage is moved from a closed to a TV to a full-recline position. The resulting pivot point for the back is projected upwardly and forwardly, to a point where an upholstered back and seat meet on a finished chair.

A rocking chair includes a foldable main body frame and a leg rest frame, where the leg rest frame includes two side support rods, two bottom rods and two slanting rods; first end portions of the two side support rods are pivotally connected to the main body frame, when the rocking chair is unfolded, second end portions of the side support rods are located forward and below the first end portions thereof; first end portions of the two bottom rods are pivotally connected to the main body frame, and second end portions of the two bottom rods are respectively pivotally connected to the two side support rods; when the rocking chair is unfolded, the first end portions of the side support rods are located above the first end portions of the bottom rods; the two slanting rods intersect and are pivotally connected at an intersection.

A chair base is revealed. A round bulge is formed on a center of a bottom surface of a bottom plate and a limit portion is gradually flattened from the round bulge toward a periphery of the bottom plate. A base body is disposed on a top surface of the bottom plate while a cover is used for covering the base body therein and enclosing the periphery of the bottom plate. Thereby the bottom plate, the base body, and the cover are connected and fixed by one another. While in use, users rock the chair by the round bulge on the bottom plate in response to their shifts in center of gravity. A rock angle of the chair is limited by the limit portion. Thereby the users will not tip the chair over while rocking the chair violently and safety in use is ensured.
