I was using bookcases and packing in my evergrowing library of DVDS several volumes thick. My daughter in law suggested this item and it was exactly what I was looking for!  It takes up 1/3 of the space (from the wall) and holds twice as much.  It is very stable, with the "footing stand" that it has.  Takes a while to assemble but only because it is so big.  I fully intend to invest in another one to get rid of my other bookcase, and to buy a second one for my daughter-in-law for her anniversary!
I am more than pleased with this product and will definitely be doing more shopping with Wayfair.
