Three 12.5-qt bins that solve the usual stacking problem: a front door on each box means the bottom bin opens without unloading the two above it. Interlocking lids grip the box below so a 28-in tower stays square instead of sliding apart, the reinforced grid rates each lid at 13 lbs, and every box holds 16 lbs of contents inside. Vent holes across the top keep shoes, linens, and seasonal clothes from turning musty. Four wheels per bin roll the stack across a closet floor with one hand, and the whole set arrives ready to fill with no assembly.
