I was really surprised that something so inexpensive worked out so well. It's basically MDF with white laminate (similar to stuff you'd get at a big box store) but it's ingeniously designed. Everything hangs off of a central rail. The poles that the clothes hang off of are metal. Everything is resizable (just cut the poles with a hacksaw as needed) and you can raise or lower the poles and shelves as part of the configuration. You're also not locked into the design shown in the picture. Liked it so much I'm buying an additional one for another closet.

Pros: Easy install, inexpensive, flexible design
