The idea behind slat wall systems is pretty simple. A slat is a strong, thin strip of wood, metal, PVC, fiberglass, or other durable material. A series of horizontal slats, with a little space above and below each one, forms a kind of wall. You can then use the spaces between slats to mount baskets, shelves, and hooks. And the benefits of wall storage are evident: slatwalls can transform your clutter into a logical, efficient storage system.
