Chairs, stool assemblies, and systems for constructing furniture. Such a chair including structural members having hinge joints at ends thereof pivotally coupling each of the members to one or more adjoining members. The chair is configured to be arranged in a collapsed configuration wherein all of the members are in the same plane and define a substantially planar shape, and configured to be arranged in an expanded configuration to define a seat, armrests, support legs, and leg braces of the chair. Such a stool assembly includes at least first and second stools configured to be stackable such that the seats of the stools abut face to face and in combination define a composite base. Such a system for constructing furniture includes multiple joints each having slots configured to receive and retain structural members and configured to be assembled with the structural members to form a piece of furniture with the multiple joints defining corners of the piece of furniture.

A collapsible structure with opposite support panels and tab panels, comprising: two structure panels; at least two support panels, each connected to the structure panels via two folding lines at opposite; and at least two tab panels, each connected to the structure panels via two folding lines at opposite sides, each contains at least two internal folding lines perpendicular to the tab folding lines; wherein when the structure is in a collapsed position, the panels are adjacent and generally parallel to each other, the structure panels are folded; and wherein when the structure is in an erected position, the support panels are perpendicular to the structure panels and the tab panels are folded by the internal folding lines, each tab panel partially adjacent to one of the support panels to shape a fixed rod supporting the internal folding lines and inserted to support a rigid distance between the structure panels.

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.

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.
