ABSTRACT:
A unitary, composite, multi-layer work area is provided which can support a plurality of work pieces thereon. The work area includes a structure which comprises a pair of outer protective covering layers and inner rigid core means, respectively. Preferably, a pair of networks are disposed between the outer covering layers and the inner core means. Either or both of the networks can be replaced with a perforated, crush-proof structure. The layers of the structure are uniformly joined one to the other substantially along the entirety of their respective adjacent surfaces to form a laminate-like support structure. Fastening means passing within the subject work area are employed to maintain the work pieces in the requisite position. The structure can be supported in a fixed or in a plurality of adjustable positions with respect to the horizontal axis.
