Recently, in the US, Dyson (as in the vacuums) has been running a television ad
featuring founder James Dyson seated at a drafting table, sketching
out ideas.  I've been unable to locate that ad anywhere online, and
unfortunately I don't know the name of the spot either.

But my interest is in the drafting table itself.  It's a fairly bold
and modern design and I'd like to find out who makes that table
(assuming it's not some sort of one-off custom piece).

I emailed Dyson and received this answer:

Thank you for contacting us! 
The drafting table used in the commercial is Heron Parigi.

Thank you!  I never even thought to email Dyson directly about it.
Brilliant!

Cheers!
