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.

A furniture member including a seat base, a seat assembly, a first and second rocker member, and a first and second rocker spring assembly. The seat assembly is movable relative to the seat base. The first and second rocker members are fixedly attached to the seat frame assembly. Each of the first and second rocker members includes a curved bottom surface in rolling contact with a surface of the seat base. The first and second rocker spring assemblies are secured to the seat base and the first and second rocker members, respectively. The first rocker spring assembly includes a first mount bracket, a second mount bracket, and a first spring that extends between the first and second mount brackets. The second rocker spring assembly includes a third mount bracket, a fourth mount bracket, and a second spring that extends between the third and fourth mount brackets.

An anchor for rocking furniture including left and right flat-bottomed elements longer than wider, with width less than half the spacing between rockers of rocking furniture to be anchored. A forward element releaseably impedes the flat-bottomed elements from separating by more than the rocker width at a first point forward of a back leg of the furniture plus a gap substantially less that the width of the wider flat-bottomed element at the first point. The forward element is vertically positioned between flat-bottomed elements above the height of the rocker at the first point. A rearward element impedes flat-bottom elements from separating by more than the rocker width at a second point rearward of the back leg plus a gap substantially less that the width of the wider flat-bottomed element at the second point. The rearward element is vertically positioned between the flat-bottomed elements below the rocker at the second point.

A zero gravity chaise chair includes a seat frame providing a head rest, a back, a bottom and a leg rest, a first bow member connected to one side of the seat frame, a second bow member connected to the other side of the seat frame, a first rolling guide connected to the first bow, a second rolling guide connected to the second bow, and a base connected to the first rolling guide and the second rolling guide. A motor may operate the first rolling guide to vary incline position of the seat frame. The motor may be algorithmically controlled to vary incline position of the seat frame such as to aid blood flow and minimize pressure points of a body positioned on the seat frame.

A mechanical extension device of a swinging seat is provided, which includes a base, a first swinging rod, a second swinging rod, an actuator and two mechanical extension units, where the base is connected to the first swinging rod and the second swinging rod in a rotating way; the actuator is arranged between the two mechanical extension units; a locking device is arranged on a second connecting rod connected to the second swinging rod in the mechanical extension unit in a rotating mode, a guide groove and a locking groove formed in the guide groove are formed in the base, the guide groove is opened towards one side, the locking device can enter the guide groove from the opened position of the guide groove, and when the locking device swings and moves the mechanical extension unit, the locking device can enter the locking groove and swing relative to the base.

A furniture member may include a base frame and a seat assembly mounted on the base frame. The seat assembly may include a seat frame, a seatback, a seat bottom, a rocker member, a legrest mechanism, and a tilt mechanism. The rocker member is attached to the seat frame and rollingly contacts the base frame. The rocker member supports the seat assembly relative to the base frame such that the seat assembly is movable between a rocked-back tilt position and a rocked-forward tilt position. The legrest mechanism is mounted to the seat frame and attached to a legrest platform. The legrest mechanism may include a drive rod coupled to a pantograph linkage that is movable relative to the seat frame between retracted and extended positions. The tilt mechanism selectively locks the seat assembly in one of an infinite number of tilt positions between the rocked-back and rocked-forward tilt positions.
