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.

An exercise chair is disclosed that includes a backrest, four legs, and a ball frame, which is configured to nestably receive an inflated ball, such that a top surface of the inflated ball may receive a sitting person. The chair includes a pressure sensor that is positioned beneath a bottom surface of the inflated ball, which is configured to detect pressure exerted by the inflated ball and calculate force measurements resulting from such pressure. The chair also includes an electronic controller/transmitter that is configured to receive the force measurements from the pressure sensor; calculate whether a person sitting on the chair jumped from the chair based on such force measurements during a defined period of time; and communicate a total number of calculated jumps by the person over a defined period of time to the person.

A frame system that is adjustable in size and shape is provided with components that move in relation to each other. The frame system uses support rails, side rails, and a center rail to configure the different components to a desired shape and size. Each support rail includes a middle support piece and a pair of adjustable support pieces that move within the middle support piece. Each side rail includes a middle side piece and a pair of adjustable side pieces that move within the middle side piece. The center rail includes a middle center piece and connecting pieces that connect to a slot within each middle support piece. Legs mount the support rails and side rails while the center rail uses a leg piece.

A furniture leg protective sock is constructed of a stretchable/expandable non-friction material, which is double-layered to form an outer layer, an inner layer, and a gap therebetween. The furniture leg protective sock includes friction material which is located on the inner surface of the furniture leg protective sock.

A support assembly for easy assembly and reliable operation is disclosed. Support assembly includes a plurality of support members, with at least one support member including connecting slot and at least one other support member having a complementary slot. Each slot features at least two tapered faces or walls to provide a wedge effect that ensures a tight reliable fit when the two members are fitted together.

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 furniture device is disclosed comprising six individual pieces that interconnect to form a cube. The pieces include two substantially L-shaped side portions, one substantially L-shaped central portion adapted to fit between the two substantially L-shaped side portions, a substantially L-shaped top portion adapted to fit between the two substantially L-shaped side portions and on top of the substantially L-shaped central portion, and two arc-sided rectangle portions adapted to fit between the substantially L-shaped top portion and substantially L-shaped central portion. The six pieces can be arranged in a various forms.

A support leg for furniture having only one opening that allows a screw to secure the support leg to one piece of furniture within the furniture assembly system is described. The support leg is constructed in such a manner that this one opening allows the support leg to support at least two pieces of furniture together within the furniture assembly system, even though the support leg is physically secured to only one piece of furniture.

A chair anchor device is provided. The device is primarily comprised of a body, an interior space, and at least one channel. The body is generally rectangular and may be filled with a heavy material, such as water/sand, to weigh the device down. The bottom surface of the body may provide additional grip to the floor to prevent the device from sliding across the floor. A chair leg may be positioned into each channel on either side of the body and secured to the device via at least one fastener to stabilize the chair and prevent it from tipping over or moving.

A stabilization device for preventing an object from falling backwards or sideways, the device comprising: an upright portion comprising an inner surface and an outer surface; a base portion mounted to the upright portion comprising at least one leg; and at least one stabilization arm, wherein the at least one stabilization arm is mounted to the upright portion and the base portion.
