Abstract: A modular green roof and/or green wall system includes a plurality of trays adapted to support vegetation and soil therein. The trays are sized such that a person may easily lift them and install them in a pre-vegetated state upon a roof or a wall. The trays are further designed to enable subterranean irrigation lines to be inserted therethrough, thereby hiding the irrigation lines from view. Biodegradable walls may be added of different heights to the trays to support different types of vegetation, as well as to create terracing for a given installation, if desired. A wicking material may be inserted into the tray and positioned such that is makes contact with wicking material in adjacent trays, thereby spreading moisture between trays through the capillary action of the wicking material.

Abstract: A chair includes a base, a backrest and a back brace supporting the backrest from the base. The base may include a seat assembly made up of a pan and a flexible support membrane over an upward opening cavity defined by the pan. The back brace may provide a flexible support for the generally planar member formed as a serpentine shape defined by a first curved portion opening toward said base and a second curved portion opening away from said base. The backrest may have an outer frame made from an extruded member having a generally tubular member and a fin coextruded with said generally tubular member to provide a fastening substrate for panels. The base may further include a leg assembly made up of a plurality of leg members and a joiner member joining horizontal portions of the leg members.
