Ever dreamed of putting that narrow gap to good use? Here’s the heroine of tight spaces! Just 4.75 inches wide, this cart rolls into places even a cat couldn’t sneak through. Four tiers and side hooks outperform a cabinet. Lightweight yet sturdy, it can handle anything from jars to cleaning supplies. The wheels have brakes so it won’t run off. You can assemble it with three shelves or two — it’s up to you.
