Be cautious purchasing this item.  There is a black elbow and a chrome elbow and I have received both, so do not have a matching set.  Additionally the seat heights vary and the pedestal seat supports are not the same size so pieces are not interchangeable.  Very frustrated that there are 2 models available.  I have worked very closely with my purchasing agent and she has not been successful in having the company check the materials prior to shipping.  Don't know what to do at this point after 3 shipments for replacements.
