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.

Systems of a footrest are described, along with a process for making the footrest. The footrest may include a base with at least four side walls connected by a bottom side. The base may be folded into a flat or box shape. The footrest may also include a container lid connected by a bottom lid and a top lid, and the base may be configured to join with the container lid. The base may also fit inside the container lid when folded, and the bottom lid of the container lid includes at least two semi-circular shaped depressions.

Paper-based elongate structures suitable for use as lumber substitutes, articles of manufacture made thereof, kits of materials including such structures, and machines and methods for making the same. Elongate structures according to the invention include a hollow outer portion formed of corrugated fiberboard sheet material and an accordion-folded inner support formed of corrugated fiberboard sheet material. The hollow outer portion has four outer surfaces that define a rectangle when viewed in cross-section transverse to a longitudinal axis of the elongate structure. The accordion-folded inner support is enclosed within the hollow outer portion. The inner support includes a plurality of first spaced-apart peaks that contact a first inner surface of the hollow outer portion and a plurality of second spaced-apart peaks that contact an opposing second inner surface of the hollow outer portion. The accordion-folded inner support structure improves the beam strength, crush resistance and lateral strength of the elongate structure.

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.

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. 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. 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.

To provide a preferable piece of temporary furniture which is less burdensome with respect to preparation, assembly and the like, and which is not subject to the problem of size mismatch between a piece of furniture and a partition. A partition-equipped bed 1, which is a piece of temporary furniture suitable for emergency use, comprises a partition and a piece of furniture which are both made of corrugated boards and are connected together. The entire partition-equipped bed 1 can be folded into a flat shape, and can be opened up from the folded state into a three-dimensional shape in the manner of a pop-up book, thus forming a partition-equipped piece of furniture that stands on the floor.

An improved furniture system, including methods of manufacture, is disclosed. The furniture may be a sofa or a bed, which is reduced to a minimum volume for transportation. A flexible foldable honeycomb structure is used in manufacturing a supporting structure, wherein the hexagonal shape of said structure is strong and stable and provides a high bearing capacity versus weight. The honeycomb structure is designed to be foldable and used for saving space and to be easier for delivery in a box that fits in a small car, wherein said structure used flaccid materials that are glued to each other in certain ways to open and close easily, and wherein the number of layers of the flaccid materials determines the expansion length of the structure.

A foldable cushion includes a cushion mechanism and a connecting mechanism. The cushion mechanism includes a seat unit and a back unit. The seat unit and the back unit are juxtaposed and movable relative to each other along a transverse folding line. The connecting mechanism includes a first endless cord and a second endless cord. The first endless cord and the second endless cord respectively extend through the transverse folding line and are flexibly arranged on the seat unit and the back unit. When the seat unit and the back unit are moved relative to the transverse folding line, the first endless cord and the second endless cord are stretched, so that the seat unit and the back unit are positioned at an expanded state by the elastic force of the first endless cord and the second endless cord.
