It is BIG - just what we wanted, and very sturdy.  Assembled easily with no problems at all (it will take two strong people), and then up against the wall for a striking architectural shelf system.  The 12 inch space between shelves is unusual and much appreciated.  Our taller books and magazine containers fit for a change, and the little divided nooks are perfect for mementos and artwork.
Looks good, adding a lot of character to a remodeled, modernized home office.
