A furniture member may include a base assembly and a seat assembly. The base assembly may include a base structure, a post, a support frame, and a height-adjustment mechanism. The post extends vertically upward from the base structure. The support frame may include a cross member and a sleeve. The sleeve may slidably and rotatably receive the post for vertical movement of the support frame relative to the base structure along a longitudinal axis of the post and for rotational movement relative to the base structure about the longitudinal axis. The height-adjustment mechanism may include a height-adjustment actuator configured to move the support frame vertically along the longitudinal axis. The cross member of the support frame may include a pair of rocker springs mounted thereon. The seat assembly may be mounted on the rocker springs and may include a seat bottom, a seatback, and armrest members.

A furniture member may include a seat assembly and a legrest assembly. The seat assembly includes a seat bottom and a seatback. The legrest assembly may include a legrest platform and articulating arm assemblies. Each articulating arm assembly may include first and second link-housings and first and second control links. The first link-housings may be rotatably attached to the seat bottom. The second link-housings may be rotatably attached to respective first link-housings and the legrest platform. The first control links may be disposed within respective first link-housings. Rotation of the first link-housings relative to the seat bottom may cause relative movement between the first control links and the first link-housings and relative movement between the first control links and the second link-housings. The second control links may be disposed at least partially within respective second link-housings and may be movably coupled to the second link-housings and to the legrest platform.

A furniture member may include a seat base frame, a seat bottom, and a seatback. The seat bottom may be attached to the seat base frame. The seatback may be attached to the seat base frame and may include a seatback frame and a seat-depth-adjustment mechanism. The seat-depth-adjustment mechanism may include a backrest support member and a seat-depth- adjustment actuator. The seat-depth-adjustment actuator may be mounted to the seatback frame and may be drivingly coupled to the backrest support member to move the backrest support member relative to the seatback frame and the seat bottom between a retracted position and an extended position.

A seating arrangement includes a support shell including a seat portion and a chair back portion each configured to support a seated user, the chair seat portion having a front region and a rear region and the chair back portion having an upper region and a lower region, where the rear region of the seat portion is coupled to the lower region of the chair back portion, a control member including a substantially flexible front support and an attachment point, where the front support engages the support shell in the front region of the seat portion and the control member engages the back portion, and a substantially rigid second support attached to the control member at the attachment point, wherein the control member is an integral, one-piece component including multiple flex regions configured to allow the support shell to move between an upright and reclined position.

Seating assemblies and methods are disclosed. A seating assembly can comprise a seat, a back support, and a frame component. The frame component can extend from a bottom portion, positioned near an underside of the seat, to a top portion, configured to maintain the back support at a position above the seat. The back support can laterally extend from a left edge portion to a right edge portion and can include a spring member at or near each of the left and right edge portions. The spring member can include at least one undulation or are providing integrated compression adaptation to a user. The seating assembly can further comprise a tilt mechanism, engaged with the frame component, including one or more leaf springs and a spring contact assembly. The spring contact assembly can be positioned on a top side of the one or more leaf springs.
