I used to work for office furniture companies when I was younger, it's a very profitable business. The place I worked for bought and sold, primarily used, furnitures. (cubicles, etc...) When businesses go under the actual cubes are the last thing anybody is really worry about and they can sell for as little as a $5-$10 per cube. The person buying them has to send guys to take them down, load them on a truck and bring the back to the warehouse. The refurb team cleans and puts new fabric on them if needed, etc...

People that are wanting to open a new office, or expand one they already have and go cube shopping. First they go online and are blown away by the cost of new cubes, then they find these dealers. Even a used cube still can cost a couple grand. It's a lot of overhead and the business isn't what it used to be, but still pretty profitable if managed well.

I remember when I used to work with office furniture, I remember how I wished I worked in a cube instead. Went to computer school and now spend my days day dreaming about not working in a cube. (I actually work from home during the summers, but that's almost over.)
