I call these two cabinets "Pottery Barn" on steriods. They are 10' long and 7' tall.
They do break down and can be used seperately. The wood is cherry with a wipe on polyurethane finish. I felt that breaking the fronts on the middle sections added to the overall design.
The Desk Unit has file cabinets with two draws over and the Media Unit has sliding draws for DVD storage.
