Do not buy this horrible piece of junk!!!!  Buyer beware!!!  Extraordinarily difficult to put together - not my first shelving unit but certainly the worst!  Shelf support clips do not secure as tightly as other products, caused product to collapse.  Caused estimated $250 damage to my hardwood floor (hardwood in area where constructing was covered) when pole became projectile during collapse.  Zero stars - in case Wayfair requires at least 1 star!!
