Provided is an iron sofa frame structure provided with a base, two supporting plates oppositely disposed, configured to support a soft package and be connected with a sofa fabric and two driving link sets respectively configured to connect the two supporting plates to the base, wherein a front rod and a rear rod are correspondingly disposed at intervals between the two supporting plates, and several elastic bearing pieces for bearing the soft package are disposed between the front rod and the rear rod. The supporting assembly is directly combined to the iron sofa frame structure, so that a structure in which an additional seat-wrapped frame is introduced to support the soft package is rejected, an existing iron sofa frame structure and a production process of an iron sofa frame are simplified, the assembling and production efficiencies are increased, materials are saved, and the cost is reduced.

The present disclosure relates to a mechanical stretching device for a movable seat unit, and a movable seat unit thereof. The mechanical stretching device includes: a linkage support that comprises a support structure configured to support the mechanical stretching device on ground and a linkage structure attachable to a seating portion of the seat unit; a back mechanism that is pivotally connected to the linkage support and is configured to attach to a backrest of the seat unit; and a leg stretching structure including a footrest element, and the leg stretching structure is pivotally connected to the linkage support, and the footrest element is attached to a footrest of the seat unit. The mechanical stretching device is configured to implement a sequential conversion or a reverse sequential conversion of the seat unit from a sitting state to a relaxing state and to a lying state.

An adjustable reclining chair having zero wall clearance has a frame and an adjustable support platform with a plurality of articulated support sections pivotally mounted with respect to one another for relative angular adjustment. An actuator means for effecting co-ordinated movement of said support sections to reconfigure the chair between a seated position and a sleeping position in which the articulated supporting sections lie in a substantially horizontal plane (H). One of the articulated support sections is a seat support inclined relative to the horizontal plane when the chair is in the seated position and substantially in the horizontal plane when the chair is in the sleeping position.

A seat positioning system includes a base frame having a pair of forward slots and a pair of rear slots, and a seat frame having a front end and a back end. The seat frame is coupled to the base frame and movable relative to the base frame. A first pair of linkages is slideably coupled to the pair of forward slots and connects the frames. A first pair of locking devices has a locked configuration adapted to prevent the first pair of linkages from sliding relative to the pair of forward slots and an unlocked configuration adapted to allow the first pair of linkages to slide relative to the pair of forward slots. A second pair of linkages slideably is coupled to the pair of rear slots and connects the frames. An actuator is pivotally connected to both the scat frame and the base frame and is configured to extend and contract to move the scat frame relative to the base frame.
