  • Patent number: 6267064
    Abstract: A furniture unit is provided specially adapted for use in laboratories. The furniture unit includes a pair of spaced-apart uprights and vibration-dampening legs extending from the uprights for stably supporting the furniture unit on a floor surface. A belt-high structural beam comprising two opposing C-shaped beams is fixedly attached to the uprights to rigidly interconnect the uprights in a spaced relationship. A plurality of worksurfaces is provided, each having a pair of cantilever brackets configured to rigidly connect to a side of the belt-high structural beam and to extend laterally therefrom. The plurality of worksurfaces is separately adjustably supported on the belt-high structural beam for vertical height adjustment, with at least one of the cantilever brackets engaging the belt-high structural beam at a location between the uprights. Shelves are attached between the uprights above the plurality of worksurfaces.
