Low, single mobile storage unit is designed with smaller children in mind. Spacious, open compartments can hold a 340-piece set of unit blocks. Kickplates prevent toe and finger pinching. Small objects can't get underneath. Storage unit is made of Baltic birch plywood for sturdy, light-duty storage. Construction employs the dowel-pin technique, increasing already-noteworthy strength. This design leaves the thickness of the material intact where most of the stress occurs. Caster brackets add triangular strength to corners where stress also occurs.
