Admittedly this is not an expensive bookcase but the quality is shockingly poor. As we were assembling it part of it just snapped off to reveal that the inside is pretty much just layers of cardboard. Should’ve sent it back but by then all the polystyrene packaging was broken up in the bin. Managed to glue it back together. Mentioned it as an aside when speaking to Wayfair and about returning another item and they were so apologetic and helpful. Received a full refund.
