An adjustable chair includes upper and lower base members, a seat assembly secured to the upper base member, and a chair adjusting mechanism. In an embodiment the upper base member is connected to the lower base member by first and second linking members each having a first end connected to the lower base member and a second end slideably received in corresponding first and second arcuate tracks disposed in the upper base member, such that movement of the second ends into and out of the tracks results in vertical movement of the seat assembly relative to the base. In a further embodiment the seat bottom and seat base comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat bottom to tilt relative to the seat base. In a further embodiment the seat bottom and seat back comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat back to recline relative to the seat bottom.

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 seat frame and the base frame and is configured to extend and contract to move the seat frame relative to the base frame.

A chair frame and a casual chair are provided. The chair frame includes a frame mechanism, a connecting rod system and a seat mechanism. The connecting rod system includes a basic component fixed to the frame mechanism; a first front arm pivotally connected to the basic component; a first rear arm pivotally connected to the basic component; a first transverse arm pivotally connected to the first front arm and the first rear arm; a second transverse arm pivotally connected to the first front arm; a second rear arm pivotally connected to the first rear arm and the second transverse arm; a second front arm pivotally connected to the second transverse arm; and a lifting component pivotally connected to the second front arm and the second rear arm. The seat mechanism includes a hip-leg supporting component, a front rocker arm and a rear rocker arm.

The seat mechanism includes a hip-leg supporting component, a front rocker arm and a rear rocker arm.

The assembly chair includes a pair of frames, a plurality of coupling rods, a plurality of pairs of depressed portions, at least one support member, and a sheet. The sheet is removably installed between the support member and the coupling rod. At least at one end portion of the sheet, the sheet includes a plurality of inserted portions along a width direction of the sheet. A flat plate is passed through at least one of the inserted portions. The support member with a flat intermediate portion is passed through another one of the inserted portions. The sheet is wound around outer peripheries of the inserted portion through which the plate is passed and the inserted portion through which the support member is passed to adjust a length of the sheet. In such state, the support member has both end portions fitted to the depressed portions on the frames.

A furniture system can include a base and a top. The base has a first surface defining a first slot and a second surface defining a second slot. The top has an end that is sized and configured to be inserted in the first slot and in the second slot. The furniture system forms a chair of a first configuration with the top forming a chair back and the first surface forming a first chair seat when the end of the top is inserted in the first slot. The furniture system forms a chair of a second configuration with the top forming the chair back and the second surface forming a second chair seat when the end of the top is inserted in the second slot. The furniture system can also be configured as various types of tables.

A luxurious motorized outdoor pool chaise lounge and luxurious motorized outdoor pool seat recliner are provided. The lounge chair and the recliner are fully motorized and include many other luxurious features. The lounge and recliner may be reserved in advance and rented on a time-of-use basis.
