Three cheers for three tiers! The aptly-named Expand-A-Shelf does exactly what it says – provides additional shelf space without having to renovate your kitchen. In my opinion, the tiered feature should be automatically built-in to all kitchen cupboards and pantries at the construction level! It just makes sense. The stadium bleacher effect allows you to see things at the back rather than guessing about what’s lurking in the dark. If your cupboard or shelf is deep enough, the actual shelf surface creates one more level of storage.
