Love this idea! Take two IKEA Expedit bookcases, frame in MDF, paint, attach casters, and bolt some stained 2x10’s to the top. Designed by the amazing Justine Taylor.

A Multi-Use Storage Space: In Adella and Nolans playroom, mom Lexi flipped two white Expedit shelves on their sides, and stacked coordinating four-shelf cubes on top of them to create plenty of storage space for her tots toys and books. Alternating straw and lime green drawers on the bottom shelves was a creative way to add color and dimension to the unit while keeping clutter hidden away. Source: Adella & Co.
