I used to buy cheap used iconic dot-com office furniture at Desk Depot [1] in Mountain View in the 90's (they've been there since '76). That must have been one of the most profitable companies during the dot-com bubble era, and I bet there's furniture that's been recycled through that same warehouse multiple times! The Desk Depot is a Silicon Valley cultural touch-stone, like the Haltek Surplus Electronics [2] [3] or Halted Electronics [4] of office furniture.
Totally OT but if you're in the area ever, Halted is a candy store for anyone with even a vague interest in electronics. I recently put together a burning man solar power box from parts there. It would have been cheaper on Amazon but it was great to be able to feel the switches I was looking at and get just the stuff I needed instead of 10 packs from China.
