This was the second one I had purchased to stack on top of my existing one. The larger compartments on the bottom are nice for my husbands shoes because the soles are wider and they can't fit side by side as well, but he can fit two pair without the divider. Or I've also used it to hold about four of my sons' pairs of shoes since they're preschooler and toddler aged. The wall anchor that comes with it makes me feel secure about having the stacked and used by my children.
