Eames / Herman Miller Aluminum group round table.
Top is light grey laminate, base is grey (see pictures)
Size: 30 inch diameter/29 inch height.
Very sturdy, useful as a dining table or work table
I purchased this table on Ebay a few years ago. It was part of a lot of such tables that had been in an office building in Chicago. I believe it was produced in the 1970s (based on my own limited research).
