I bought it thinking it was a bookcase because Wayfair listed it as 'Etagere Bookcase', but the manufacturer listed it as '4-tier multipurpose storage rack shelving unit w/bins', recommended maximum wight for each shelf is 15 pounds. If I had known it I would not have bought it, but too late to return as I opened it already. Fine as light weight storage unit for young children's room, the built is slightly wobbly with a warning that children must not climb on it.
