Abstract: Cushioned components are arranged to fit together in laterally immobilized fashion to form a furnished interior for the bed of a pick-up truck. The assembly is constructed of modular pieces which, when assembled, form a pair of seats above the wheel wells of the truck bed and a storage compartment extending across the width of the truck at the forward end of the truck bed. All surfaces of the assembly that are directed toward the truck bed interior are cushioned with carpeting, fabric, or padding. The modular components may be quickly assembled and disassembled, so that the bed of the pick-up truck may be utilized for heavy duty work within the furnished interior assembly, and then transformed into a luxurious den within the space of a few minutes.
