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.

Furniture pieces which incorporate load-bearing or non-load bearing structures in which water or other material may be stored. By incorporating such storage capacity within furniture, a user may take advantage of space that would otherwise be unused or unusable to unobtrusively and conveniently store an emergency water supply or other desired material.

Methods of fabricating a natural pesticide structure include obtaining at least one raw material; forming at least one natural pesticide building material from the at least one raw material by applying at least one natural pesticide substance to the at least one raw material, the at least one natural pesticide substance having intrinsic pesticide properties and including any combination of the following: garlic, lavender, gardenia, peppermint, wintergreen and lemon grass; and fabricating a natural pesticide structure from the at least one natural pesticide building material. Natural pesticide structures are also disclosed.

A chair assembly includes a back support arrangement including a back support arrangement, a seat support arrangement and a four-bar arrangement that includes a rearward end and a forward end that is adjustable between a raised and lowered positions, and an arm rest assembly adapted to support the arm of a seated user thereon and supported on the forward end of the four-bar arrangement, wherein the rearward end of the four-bar arrangement is pivotably supported from an arm support structure for pivotable movement about a substantially vertical pivot axis such that the forward end of the four-bar arrangement is moveable between a first position and second position located laterally outward from the first position, and wherein the substantially vertical pivot axis is located forwardly of a rearmost edge of an upwardly-facing surface of the seat support arrangement.

A chair control assembly includes a base structure having first and second pivot points spaced from one another, a seat support structure coupled to the first pivot point, a back support structure coupled to the second pivot point and adapted to move between first and second positions, wherein the base structure does not move as the back support structure moves between the first and second positions, and a control link pivotably coupled to the seat support structure for rotation about a third pivot point and pivotably coupled to the back support structure for rotation about a fourth pivot point, wherein the third pivot point is rearward of the fourth pivot point when the back support structure is in the upright position, and the third pivot point moves forward relative to the fourth pivot point as the back support structure moves from the upright to reclined positions.
