For the money, these units are awesome.  I bought four to literally fill a wall with storage for my art studio.  I chose the 16" depth so they didn't overtake the room and find them very roomy!  They are surprisingly sturdy and quiet easy to put together (did all four myself in under 4 hours). My studio is a bedroom with lots of traffic on the way to a common room and these were just what I needed to hide my mess.  A very attractive set.  I'm about to purchase the matching short units to place atop the 2 middle units for additional storage.  Great product.
