A foldable chair, comprising a seat portion and a telescopic side wall includes rings of varying diameters consecutively arranged. A topmost ring is mounted to a bottom surface of the seat portion and has a smallest diameter. A bottommost ring has a largest diameter. In deployed position, the telescopic side wall is opened or partially folded to set and lock a desired height of the chair. In fully retracted position all of the rings are disposed adjacent the bottom surface of the seat portion. Each ring is an integral unit configured with a locking arrangement that selectively locks it to an adjacent ring. In some embodiments, a security lock centrally disposed along a height of the chair substantially perpendicular to the varying diameters of the rings secures the locking arrangement. A table uses the foldable chair as a leg and can store several, for example four, foldable chairs.

A folding chair comprises a front leg assembly having spaced inner rail members, a rear leg assembly, and a seat assembly. The rear leg assembly comprises spaced legs pivotally connected to the inner rail members about a first pivot axis, which is substantially coplanar with the longitudinal axes of the inner rail members. The seat assembly comprises spaced arms having distal ends pivotally connected to upper ends of the legs about a second pivot axis, and central portions pivotally connected to the inner rails about a third pivot axis substantially coplanar with the first pivot axis. The third pivot axis is moveable along the longitudinal axes of the inner rail members and toward and away from the first pivot axis as the chair is reconfigured between its deployed and folded orientations.

A folding storage stool on wheels, including: a foldable stool body; a cover for covering an upper opening of the foldable stool body in an unfolded state; an inner support plate for supporting the foldable stool body and arranged on a bottom of an inner cavity of the unfolded stool body; and movable wheels arranged at a bottom of the unfolded stool body. Side folds are provided on middles of two opposite sides of the foldable stool body. A bottom fold that is inwardly folded is provided at a bottom surface of the foldable stool body. After the inner support plate is removed from the foldable stool body, the two opposite sides with side folds are folded inwardly along the side folds and the bottom surface is folded along the bottom fold, forming a folded body which is accommodated in a cavity of the cover.

A portable mattress seating apparatus attachable to a mattress. The portable mattress seating apparatus clips onto a location on the peripheral of any conventional mattress. The apparatus has a retaining member that is retained under a mattress and above the box spring. The retaining member is attached to a vertical member adjacent to the side of the mattress. The vertical member is attached to another seating member that is oriented parallel to the top of the mattress face. The seat member is attached to a back-rest member. The back-rest member is attached to the seating member distal to the side of the mattress. The back-rest member is adjustable, allowing the back rest to be at acute, obtuse or 90-degree angles to the seating member. Further, the apparatus includes supporting members to spread the weight of a seated person.

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.
