High end desk made by Bensen (bensen.ca). The desk model is Homework. The top and drawers are all walnut, and the base is chrome. The right side drawers are two small drawers for shallow items, and the left drawer is a file drawer. It measures 64" long, 27.5" wide and 29" high.
I purchased from Alteriors in 2012 for $3400, and it sells new for $4600. It is in excellent condition.
