I've mentioned the evolving Late Night with Seth Meyers set and desk, and a reader recently pointed out that they tore the whole thing down and started from scratch. New backdrop, new desk, new chairs, new everything.
The desk is a solid modern piece with some metal flourishes and looks like a desk from a Conan set, which is a good thing. I think Conan had some of the best talk show sets out there. The guest chairs look like something out of a Pottery Barn catalog. But, Seth kept some of the mid-century look with a Eames Aluminum Group Executive chair for himself.
