A 31.5-in height keeps this 3-tier bookcase below window level, so it works as a low unit under a window or behind a sofa while the 135-lb tabletop takes a lamp, a printer, or a record player. Two shelves adjust through 5 positions each to fit books, files, or storage boxes of different heights. A middle support leg carries the 47-in span, giving a 345-lb total rating with 33 lb in each cube. A 6-in floor clearance leaves room for a vacuum head, and the waterproof surface wipes clean.
