This is a bit of a bump, but hey, I'll make my very own thread just for this if people don't like old threads coming back like zombies.
Found two maybe-eames chairs in a utility room at one job. I'm having trouble figuring out of they're real, or knockoffs since I haven't been able to find good info on what to look for yet, but:
*Legs form an H shape under the seat, bolted to four rubber pads.
*Are the "seafoam green" type with visible fibres
*Legs are silver, no finish
*White plastic feet
*Rectangular label with patents but no Herman Miller logo anything like the images I've seen with embossing or metal labels, etc.
Found out more. This is one of the more common bases, but apparently an earlier/more sought-after shell. People take these things and sell just the shell or tack on the more rare legs and jack up the price!
I was back there today to finish something off, and took a seat in one of them. For a nonadjustable formed fibreglass chair these are pretty comfy! I wouldn't want to be in them for hours on end, but much more supporting than I expected. I just might try and get one of these off them.
