Six shelves branch left and right off a central metal spine, giving a 15.5-in wide footprint the presence of a piece of art rather than a storage unit. At 48 in the top shelf stays within easy reach, and the 10-in depth means the whole thing tucks against a wall in a hallway or beside a desk. Two units placed side by side mirror into a wider display wall, or each can work alone in a different room. The middle shelf carries 44 lbs and every other shelf 22 lbs, with two anti-toppling kits included.
