Guardrails 4 in high run along the top shelf, taller than the usual lip, which keeps stacked books and boxes from sliding off a unit that stands 48.5 in from the floor. Four shelves at 30.5 x 10 in sit 13.5 in apart and hold 33 lbs each. Pillar construction in engineered wood with PE and PP fittings brings the weight to 34 lbs across a 31.5 x 10.5 in footprint. An anti-tipping kit is supplied for wall anchoring. The rustic brown and black finish suits an industrial-styled study or living room.
