Did Herman Miller make the contract base table in beige?  

I don't know if the color is original or not but it looks like the real thing.

I've seen different colored columns (including cream), but not sure about the legs.

The color of some the plastic units used by Herman Miller and part of the Action Office 2 system for hospitals/healthcare use was beige or putty(?) in color. The contract base table you have might have been offered in conjunction with that system but contact Herman Miller to confirm.

Thanks a lot everyone. The feedback is much appreciated.
Cheers.
