An item such as a fabric-based item or other item may have one or more actuators. An actuator may have a conductive strand of material. A control circuit may supply a current to the conductive strand that induces a length change in the conductive strand due to ohmic heating and associated thermal expansion effects. The control circuit may be used to activate the actuator in response to user input that is supplied to an associated input device such as a switch, capacitive sensor, force sensor, light-based sensor, or other input component. The fabric-based item may include fabric such as woven fabric or knit fabric. Strands of conductive material may serve as signals paths for supplying current to conductive strands in actuators. Magnetic-field-based actuators may be formed by coiling conductive strands around tubular support structures such as piping in fabric-based items.

Provided is a folding storage stool which comprises a foldable stool body, a stool cover, and a supporting board. The stool body comprises an inner cavity and an upper opening; the upper opening allows the inner cavity in communication with outside. The stool cover is located upon the stool body and covers the upper opening. The supporting board is located at a bottom of the inner cavity and support the foldable stool body to maintain an unfolded state. The stool cover comprises a first cover part and a second cover part. A pivot end of the first cover part is pivotably connected to the second part, and a free end of the first cover part is capable of being pivotable away from the upper opening.

Among other things, a piece of furniture is formed from three separate precut pieces of flat cardboard. A first one of the pieces has a bottom edge to rest on a floor with the first piece rising vertically from the bottom edge and has at least one slot at an upper edge of the first piece. A second one of the pieces has a bottom edge to rest on the floor with the second piece rising from the bottom edge and having at least one slot at an upper edge of the second piece. A third one of the pieces has a crease across the piece and at least two slots along at least one edge that is parallel to the fold. The piece of furniture is formed by mating the one slot in the first piece with one of the slots of the third piece, folding the third piece of cardboard at the crease, and mating the one slot in the second piece with another one of the slots of the third piece, with the third piece folded along the crease.

A knee-rest economic chair is provided. The knee-rest economic chair is formed from a unitary construction, fastener-less assembly, wherein the chair provides an elevated posterior condition as an elevated knee rest for seated users. The chair may be assembled from a plurality of components all of which are formed from a planar blank of one material. The components have tabs and slots for joined adjacent components that results in a seat component spaced apart and elevated above a knee support component, positioned relative to each other in an elevated posterior position, wherein gravity secures the resulting tab-slot and slot-slot joints, making separate fasteners unnecessary.

A chair includes a back member and arm brackets. The back member is tapered toward an end that is adjacent to a seat. The arm brackets are attached under a bottom portion of the seat. Each arm bracket is adjustable to provide a seat clearance area for the seat when one or more of the arm brackets are adjusted up to approximately 90 degrees from an original upright position.

An upholstered piece of furniture including a frame having a front frame member, an opposing back rest, and two arms at opposite ends of front frame member and backrest, wherein at least one of the front frame member and opposing back rest includes a wood component, and wherein the arms are made of molded plastic and at least one of the arms is coupled to the wood component. The upholstered piece of furniture includes covering material, wherein at least a portion of the at least one of the arms is covered by the covering material.

There is provided an ergonomic chair which is produced from flat components. The components may be made of paper. The components are designed using parametric equations which take the targeted user's proportions into account. The components are then folded, joined, and coated with strengthening material. The chair has a seat, a base, and three legs connecting the seat to the base. The base contains a counterweight mass for keeping the chair in a default upright position. The base contains an accelerometer which can transmit data to a computing device to track a user's posture and other health-related data.

The present invention relates to a construction kit for a collapsible frame structure (1), wherein the construction kit is characterized in that the construction kit comprises flat components of type A (15, 25, 35) and components of at least one type B (20, 30, 40, 45), which are each formed in the shape of rectangles, which each have two long sides and two edge sides, wherein the components of type A (15, 25, 35) and of type B (20, 30, 40, 45) each have a thickness D and each have an identical length L and an identical width W, the components of type A (15, 25, 35) and of type B (20, 30, 40, 45) are each subdivided into n equally large sections of length L/n, which are bounded by n+1 sectional boundaries, wherein the edge sides of the components of types A and B (20, 30, 40, 45) form the respective outer sectional boundaries and the central vertical line between the long sides of the respective components forms the central sectional boundary, wherein the central vertical line is an axis of symmetry S, and wherein, in the components of type A, on a long side of the respective component, n2 slots are arranged along a partial length of the respective sectional boundaries and are located between the edge sides and the axis of symmetry S, and wherein, in the components of type B (20, 30, 40, 45), n4 slots are arranged along selected sectional boundaries and are located between the edge sides and the axis of symmetry S, wherein, starting from a long side, some of the n4 slots are arranged along a partial length of the respective sectional boundaries, and, starting from the other long side, the other n4 slots are arranged on the respective other sectional boundaries, and wherein, starting from a long side, at least 2 of the n4 slots of the components of type B (20, 30, 40, 45) are each arranged along the sectional boundaries and are directly adjacent to the axis of symmetry and, furthermore, starting from the other long side of the component, at least 2 of the n4 slots of the component of type B (20, 30, 40, 45) are arranged along the sectional boundaries and are adjacent to the respective edge sides, and n is 8, 10, or 12.
