A collapsible and convertible frame assembly movable between an expanded configuration and a collapsed configuration includes a first unit including a first frame having a plurality of first scissor assemblies each including a first frame member pivotally coupled to a second frame member at a pivot point. Frame members of adjacent first scissor assemblies are coupled to a first upper connector assembly or a first lower connector assembly. A second unit is removably coupled to the first unit. The second unit includes a second frame having a plurality of second scissor assemblies each including a first frame member pivotally coupled to a second frame member at a pivot point. Frame members of adjacent second scissor assemblies are coupled to a second upper connector assembly or a second lower connector assembly. An assembly unit removably couples the first unit to the second unit.
