A rocker chair having a frame and a longitudinal spring member extending from the frame, at or near a surface on which the chair is supported for rocking motion. The spring member includes an anchored portion anchored to the frame, and an extended portion extending from the anchored portion and is free to flex or bend against spring bias of the extended portion, wherein the extended portion is bendable upward from the support surface against spring bias of the extended portion. The frame of the rocker chair may be collapsible to convert from a collapsed configuration for stowing, to an extended configuration for seating a person. The spring member may include an anchored portion anchored to at least a portion of a bottom of the frame, and an extended portion extending from the anchored portion, wherein the extended portion is bendable against spring bias of the extended portion.

A chair that can transition from an upright position to a reclined position includes a base to rest on a floor, a post upstanding from the base, a chassis affixed to a top of the post and having left and right extensions, armrests extending upward from the left and right extensions. A seat is made up of a seat pan and a seat upper support frame, which are positioned under and above the chassis respectively and has a hole through which the post extends. A backrest has a lower end pivotally joined to the seat and a pivotal connection to each of the armrests, so rearward pressure on an upper area of the backrest causes pivoting of the backrest at the armrests and at the seat, pushing the seat forward to a reclined position in a synchronous motion.

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A spring actuated rocking mechanism can be attached to the legs of a collapsible chair to allow for the user to rock in the collapsible chair. The mechanism may be attached at the factory or retrofitted to the chair. The rocking mechanism can be attached to the end of a leg or disposed within a leg, having a leg portion above and below the mechanism.

A structural component may have a flexible structure with at least one adjusting mechanism, which may be formed at least from a plurality of folded elements or lever elements and spacing elements that are coupled to one another in such a way that their upper surfaces are connected to one another by an upper flat element and their lower surfaces are connected to one another by a lower flat element. The upper flat element and the lower flat element may be configured to be moved in a defined manner in the event of a tilting movement of the flexible structure.
