Stackable stools include rocking surfaces along which the stools can be rocked to allow a user to sway to and fro. The stools have rest surfaces that provide stable inclined positions of the stools. The stools can be stacked together to save space. The stools define holes allowing the stools to be stacked on a pole.

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.

An outdoor chair is provided that can include a seat, a pair of front legs, a pair of rear legs, a backrest, and a pair of armrests. The pair of front legs and the pair of back legs can both depend from the seat. The backrest can be disposed adjacent to the seat. The pair of armrests can be coupled to the front legs and the backrest, where each armrest can be coupled to the backrest with a flared protrusion. The rear legs can include an angled leg extension and the seat can include a plurality of horizontal slats.

A stackable frame that may couple to the planar underside of structures and act as support may be formed by vertical downwards and outwards sloping tubular leg members that are connected at their tops by a rigid inverted square tray and at their bent lower parts by outward convex curved pipe members disposed in a plane. In different embodiments, the frame may comprise different member cross-sections and dimensions of the longitudinal members for the support of different embodiments of attachable tops with which different functional objects like tables, chairs and stools may be formed. Aggregate frames may also constitute supports for large platforms or other elevated surfaces. Identical attachable table tops may, in turn, be nested and stacked such that their normally exposed surfaces are protected whilst a stacked configuration.
