The present invention provides a chair and a chair lifting adjustment control mechanism thereof. The chair lifting adjustment control mechanism comprises a base, an executing member slidably connected to the base for pressing a pushbutton of a telescoping member, and a cable-driven assembly with one end connected to the executing member to enable the executing member to produce a horizontal displacement. The cable-driven assembly comprises a dragline with one end connected to the executing member, and the executing member has a driving ramp for facing the pushbutton and pressing or relaxing the pushbutton during the horizontal displacement.

A tiltable stool includes a seat support, a seat, and a tilt mechanism. The seat is mounted to an upper end of the seat support. The tilt mechanism allows the seat to tilt in a desired direction. The tilt mechanism includes a coiled wave spring, an upper spring retainer and a lower spring retainer, a fastener bolt, and a tilt limiter. The upper spring retainer and the lower spring retainer are disposed opposite each other to sandwich the coiled wave spring therebetween. The fastener bolt pivotably holds the upper spring retainer in position. The tilt limiter is disposed inside the coiled wave spring and is secured to either one of the spring retainers. The tilt limiter includes a conical surface thereon which contacts a contact surface when the seat tilts to a predetermined tilt angle. The upper spring retainer is secured to a lower end of the seat support.

The collapsible lovemaking apparatus has an elongated housing having opposing ends. A floor, a top platform, opposing sidewalls, and a rigidly fixed end wall having a handle form the housing and define a hollow interior. A chair platform is slidably mounted on telescoping tubes attached to the floor, the platform being slidable out of the open housing end and supported at one end by wheels. An adjustable height pedestal chair is mounted on the platform, the chair back being rotatable 180 to define an end wall closing the open end of the housing. A second chair seat having a reclining chair back is mounted on a trolley on the top platform facing the adjustable height chair, the reclining back being collapsible to a flat position. The pedestal chair and the trolley-mounted chair seat may roll towards and away from each other to facilitate love making.

A collapsible picnic table having a tabletop and table supports that extend downward from the bottom surface of the tabletop in a use position and are adjacent the bottom surface of the tabletop in a stored position. Seat supports, pivotally attached to a first seat, rotate simultaneously with and in the same direction as the table supports. In a use position, the seat supports extend downwards from the first seat and are adjacent the bottom surface of the first seat and extend outwards from the table supports in a first stored position. The seat supports are pivotally attached to the table supports and rotate orthogonally to the rotation of the table supports from the first stored position to a second stored position, where the seat supports are adjacent the bottom surface of the first seat and are adjacent the bottom of the tabletop and table supports.
