Abstract: Discussed herein are modular frame assemblies, and methods of forming modular frame assemblies. A modular frame assembly includes a first and second lateral frame member each comprising an elongated transverse portion including a flange portion, the transverse portion including an upper edge, a first and second side frame member each comprising a first end, a second end, and a cross panel extending therebetween, the first and second end including one or more receiving members to receive the flange portions of the first and second lateral frame members, and a top planar member having an upper surface and lower surface, the lower surface including one or a plurality of chambers to receive the upper edge of the transverse portion of the first and second lateral frame members.
