A material handling device includes a base, a side, a support member, and a resilient biasing member. The side extends from the base and defines a device interior with the base. The support member is disposed within the device interior proximate the side. The support member includes a cam and is rotatable between a material handling device stacking position and a material handling device nesting position. The biasing member is coupled to the side and is configured to engage the cam and thereby urge the support member into one of the stacking and nesting positions. The resilient biasing member is also configured to effect a translation of the support member towards the side as the support member rotates from a position intermediate the stacking and nesting positions to the one of the stacking position and nesting positions.
