Unfortunatley, cannot say anything kind about this appalling put together yourself bookcase. over  a third of the dowel rods snapped as soon as put under mild pressure. Guide line markings for holes did not match up. Instructions say use an ordinary screwdriver, but a cordless electrical would be better advised, could 
hardley get a purchase & the gold nails for the backing would just not hammer 
through. Oak skirting boards came with no hole guides, But did provde screws. 
Have just leant up around the base. Hours of hard & frusrating work. Will not purchase any item flat pack again from Wayfair. Very shoddy & very disappointing.
