Abstract: A modular step stool system according to various embodiments can include a plurality of stepping blocks comprising a first stepping block and a second stepping block configured to support a user's body weight. A plurality of interlocking elements is interposed between the first stepping block and the second stepping block for horizontally and vertically interconnecting and interlocking at least the first and second stepping blocks to form a raised step platform. Some of the plurality of interlocking elements include sub-couplings which are configured to provide simultaneous horizontal and vertical interconnections. Some embodiments of the device include raised walls configured within the side walls and corner tabs inserted within the corners of the stepping blocks and configured having a profiled selected based upon the shape of the sub-couplings to facilitate stacking and interconnections in at least one of a horizontal, a vertical, a perpendicular, and an offset configuration.
