Abstract: 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.

Abstract: A piece of furniture such as a standing desk is constructed of intersecting folded prisms provided with a novel slot joint system which affords lateral and torsional stability, simplicity, and long life to such furniture.

Abstract: Among other things, a piece of furniture is formed from three separate precut pieces of flat triple wall 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.

Abstract: A piece of furniture such as a standing desk is constructed of intersecting folded prisms provided with a novel slot joint system which affords lateral and torsional stability, simplicity, and long life to such furniture. Among other things, in some implementations, a piece of furniture is formed using four sheets of corrugated fiberboard die-cut with slots and scores. A first one of the pieces is a sheet of corrugated cardboard folded into interconnected, adjacent triangular prisms (which we sometimes refer to simply as conjoined triangle prisms) that provide a work surface. A second one and third one of the pieces are sheets of corrugated cardboard folded into conjoined rectangular prisms that provide mirrored (relative to one another in the finished piece of furniture) vertical supports that elevate the work surface above the floor. A fourth one of the pieces is a sheet of corrugated cardboard folded into a rectangular prism that serves as a support brace for lateral stability.
