Four-tier corner bookshelf with a 56-in tall frame and 14.5 x 14 in base maximizes vertical storage while using minimal floor space. The 360° rotating design on a swivel base with ball bearings lets you turn the shelves to reach books or decor from any angle, then lock the unit in place with the safety lock. Each shelf supports up to 22 lbs, with square grid bottoms and translucent panels helping to support and organize items. A collapsible structure, raised top edges, and anti-slip foot pads work together to keep the unit stable in use.
