Abstract: A seat back for an office chair is efficiently manufactured and assembled. The seat back includes a tensioner for tensioning a flexible support on the structural frame. The tensioner is connected between the lower edge of the flexible support and the upright members of the frame such that the tensioner stretches the flexible support between the upper and lower edges of the flexible support and maintains the flexible support in tension on the structural frame. An armrest mount may be formed integrally with each of the upright members of the structural frame, and an armrest housing vertically adjustably mounted to each of the armrest mounts. An activation mechanism is positioned adjacent to the lower end of the armrest housing, and is connected to a lock element such that movement of the activation mechanism toward the upper end of the housing causes the lock element to move to an unlocked position.

Abstract: An office-type chair includes a back support having a support frame, front and rear shells, a cushion and a cover. The perimeter edge of the cover wraps around the side of the cushion and the front shell and is inserted between the front and rear shells to form a finished edge for the cover. The front shell may include a central flex section, and a lumbar pad may be positioned between the front shell and the rear shell and adjacent to the central flex section. One or more lumbar enhancement ribs on the front shell may augment the pressure distribution of the lumbar pad as it is vertically adjusted.

Abstract: The present invention involves a horticultural growing rack used for growing plants. The horticultural growing rack offers a variety of benefits to a plant grower. The horticultural growing rack can be modified to create various sizes of racks. The rack can also hold various attachments such as a light bar, ballast bar, and tray holders. This rack can be easily shipped and stored.

Abstract: The present invention relates, in general, to an water cooled horticultural growing light and a method of using the same. More particularly, the present invention relates to a water cooled horticultural growing light and method wherein water flows through outer glass tubes to cool the light source which sits inside an inner chamber of the invention. This invention allows for the light source to be placed in close proximity to the plants. This invention can be used in nurseries and other growing facilities to increase productivity by allowing plants to receive increased solar rays without the damaging effects of heat.
