The having of my drawers (and even more importantly my children's drawers) in horizontal rows has vastly, vastly improved my life. I can find everything! They can find everything! I have a much better sense of what clothing they never wear because over time the unworn pieces migrate to the back of the rows, so I actually know how much functional clothing they have and when they need new clothing! Plus it is, for me, simply aesthetically more pleasing, and getting a positive aesthetic moment each time I open a drawer is really, really nice.
