Perched over the desk, this 2-tier desktop bookshelf clears vertical space with 55 lbs shelves while its metal pegboard backing customizes the workspace with hooks and small trays. The 35.5 x 21 in clearance below fits monitors up to 32 in, anti-falling guardrails and back panels hold books in place, and adjustable foot pads with two anti-tipping kits steady the hutch on any desktop.
