Reconfigurable modular storage system

A reconfigurable frame attachable to a storage unit, comprising:

• a first end frame member having a first end and a second end;
• the first end frame member being attachable to the storage unit in a first orientation relative to the storage unit, wherein the first end of the first end frame member is positioned vertically above the second end of the first end frame member;
• the first end frame member being attachable to the storage unit in a second orientation relative to the storage unit that is different than the first orientation, wherein the second end of the first end frame member is positioned vertically above the first end of the first end frame member;
• at least one base member attachable to the first end of the first end frame member;
• wherein, when the first end frame member is attached to the storage unit in the first orientation and the at least one base member is unattached to the first end frame member and is instead attached to a different portion of the frame, at least a portion of the first end of the first end frame member serves as a raised end railing of a topmost horizontal surface of the storage unit;
• and
• wherein, when the first end frame member is attached to the storage unit in the second orientation and the at least one base member is attached to the first end of the first end frame member, at least a portion of the at least one base member serves as a load-bearing support for the first end frame member and for the storage unit.
