Abstract A knock-down furniture assembly comprises substantially identical top frame and bottom frame members. Fasteners are coupled to the top and bottom frame members a side wall member rotatably receives an elongate mating fastener extending substantially from top to bottom thereof. The elongate mating fastener is configured for mating with the respective fasteners of both top and bottom frame members for defining an assembled condition of the furniture assembly. A knock-down drawer assembly comprises an end panel and two complimentary side panels and hinges for hingedly joining the complimentary side panels with the end panel. A preformed drawer guide assembly is also provided for mounting one or more assembled drawer to the assembled frames and sides of the furniture assembly.
