I've had so many people asking about this shelf compartment that I went on line to try to find it or something similar and I can't find an exact match. Sorry! I am going to keep trying. One thing I realized is that those compartments are the perfect size for CDs, so I am looking on sites that have CD storage as well.
The closest things I found were at Pottery Barn Teen (pbteen.com). They're not quite the same and are more expensive, but this is the best I can do right now:

Here's a tip about Pottery Barn. If you have found an item on the main Pottery Barn site that you are thinking about purchasing, also check PBteen.com or their Pottery Barn Kids site. A lot of the time, they will have similar items to the Pottery Barn site for much less $. I bought a wire sculpture on the PBteen site for $39.00 and the Pottery Barn main site had their version of the same subject matter for about $150.00.
