A control mechanism (20) for a chair(100) comprises a baseplate (21) configured to be coupled to a chair base assembly(102), a support plate (22) configured to be coupled to a chair seat(103), and an elastic element (23) arranged between the base plate (21) and the support plate (22). The elastic element (23) enables the support plate (22) to be tilted with respect to the base plate (21) around a first tilt axis and a second tilt axis different from the first tilt axis. The control mechanism (20) further comprises a control handle (24) configured to be actuated in an actuating direction (34), and at least one stop element (26A-26D). Each stop element is arranged between the base plate (21) and the support plate (22) and configured to limit a minimum distance between the base plate (21) and the support plate (22) at the position of the corresponding stop element (26A-26D). A stop element adjust mechanism (28) is coupled to the control handle (24) and configured to adjust the minimum distance of each stop element in response to actuating the control handle in the actuating direction (34).
Aspects herein are directed to systems and methods for synchronization of actuators to reposition furniture units. Specifically, a master control box receives input to reposition a furniture unit from one position to another and communicates the input to a plurality of control boxes. Then, each of the plurality of control boxes assigns a virtual axis to each of a plurality of actuators attached to each associated control box. Furthermore, each of the plurality of control boxes assigns a transfer function to each of the plurality of actuators. The transfer function is used by the actuators to transform an output of the virtual axis to determine a target position. In this way, the plurality of actuators can reference the same virtual axis for synchronization purposes, but use different transfer functions to maintain complex relationships between the positions of each actuator. Based on the target position, the actuators reposition the furniture unit.

POCKETED SPRING COMFORT LAYER HAVING AT LEAST ONE FOAM LAYER AND METHOD OF MAKING SAME
A pocketed spring comfort layer (16, 50, 216, 56, 56', 16a, 56a, 132, 140) for a bedding or seating product (10, 60) has pockets (44, 244, 84, 84', 44a, 84a) characterized by the individual mini coil springs (28) of the comfort layer being pocketed with between at least one cushion assembly (22, 64) and a sheet of polypropylene fabric (24, 66). Each cushion assembly (22, 64) includes at least one foam layer (29, 67). A segmented seam joins the cushion assembly (22, 64) and the sheet of polypropylene fabric (24, 66) around each of the mini coil springs (28) of the pocketed spring comfort layer. The method of making the pocketed spring comfort layer includes compressing the mini coil springs (28) and creating pockets (44, 244, 84, 84', 44a, 84a) with a welding horn (32, 72, 32a, 72a) and an anvil (74, 74a, 42, 42a).
A pocketed spring assembly (12, 12a, 12b, 12d, 12e, 12f, 12g) comprises a plurality of parallel strings (26b) of individually pocketed springs (28). Each string (26b) is joined to at least one adjacent string. Each string (26b) has first and second opposed plies (48, 50) of fabric and a plurality of pockets (38, 38') formed along a length of the string by transverse segmented seams (54, 54') joining the plies. Gaps (66, 66', 70, 70') between the segments of the seams (52, 52', 54, 54') allow air to pass into and out of the pockets (38, 38') despite the fabric being impermeable to airflow through the fabric. The fabric has at least four layers (76, 80, 78, 76). The size of the gaps (66, 66', 70, 70') determines the firmness or "feel" of the pocketed spring assembly (12, 12a, 12b, 12d, 1 2e, 12f, 12g) or portion thereof.

A posturized comfort layer (16, 60, 66, 100, 110, 120) for a bedding or seating product has different sections (50, 52) of different firmness due to different mini coil springs (28, 30) within the sections (50, 52). The springs (28, 30) may be individually pocketed between two sheets of non-woven polypropylene fabric (22, 24, 74, 76) joined with circular seams (32) or rectangular seams (80). Each circular seam (32) joins opposed pieces of fabric (22, 24) around one of the mini coil springs (28, 30) with curved segments (26). Alternatively, rectangular seams (80) join opposed pieces of fabric (22, 24) around each of the mini coil springs (28, 30) with linear segments (78). Regardless of the shape of the seams, the different firmness of the different sections (50, 52) of the comfort layer may be due to the mini-coil springs contained in the pockets.
A mechanism is provided for a seating unit that moves the seating unit between closed, TV, and fully reclined positions. The mechanism allows positively holds a footrest in a closed position, preventing the footrest from sagging over time. The mechanism includes a linkage that forces a link connected to the footrest to move initially upwards as the footrest moves from a closed position to an extended position. The weight of the mechanism holds the footrest positively closed, until a force is exerted that is great enough to move past the point where the link on connected to the footrest can descend.
