Abstract: A slat (116) is arranged to co-operate with substantially similar slats (117) for the construction of structures, primarily garden furniture. Each slat defines a substantially C-shaped cross section with a central element (501) and two longitudinal elements (502, 503) attached to the central element. Locking teeth (505) are applied to an external surface (504) of the central element, arranged to radially extend about a connecting hole (506). The connecting hole receives a spindle (507) arranged to securely hold the slats in position. With the spindle loosened, it is possible to re-configure the furniture for different purposes. However, with the spindle held tightly in place, the furniture becomes rigid and suitable for supporting body weight.

Abstract: A foldable lounge chair provided for both sitting and comfortable lounging positions wherein the back of the chair keeps upright while the seat is occupied and when the user lies his back against the back of the chair, the back of the chair inclines gradually backward and simultaneously makes the seat raise from its original lower horizontal position. When the back of the chair is inclined to the desired angle, a inclination setting button can be firmly fastened that the inclined position of the back may thus be set. When the inclination setting button is loosened, or the user no longer lies his back against the back of the chair, the back can automatically return to its original upright position. If not in use, the chair can be quickly folded flat for storage and carrying.

Abstract: A portable reversible chair apparatus with pivotal connections enabling the device to be converted from a "posture" chair configuration to a conventional chair configuration simply and quickly. While the device is in the "posture" chair configuration adjustments are possible that allow users of different size to select the seat angle and the seat to knee rest distance which is most comfortable for them. The knee rest is designed to flex in the verticle plane allowing the seated user to shift weight and position comfortably and safely. The critical joints of the chair pivot thus eliminating racking of joints. Rigidity is derived from triangulation rather than from the size of the joints. The device is very stable due to its large base and sits well on an uneven surface because it rests on three points rather than the traditional four.
