Chromcraft Sculpta Chairs (a.k.a Star Trek Chairs)
In addition to being a LEGO geek, I'm also a furniture geek (specifically space age design from the late 60's to early 70's). One of my ultimate 'holy grail' items, which I never thought I'd obtain, was a set of Chromcraft Sculpta chairs. By pure good fortune I was able to score a set of 4 from a local Craigslist ad. Some guy in Milwaukie, Oregon had these stuffed away in his garage. The ad stated that they were in need of a good cleaning, which was a gross understatement. These chairs could not have been more filthy. They were totally caked with house paint, fingernail polish, cake frosting, spaghetti-O's, glitter, play-doh, and all manner of unidentified goo. I didn't know to what degree I would be able to restore them, but I decided to risk it. I offered (and got the set) for $200. I disassembled the chairs as much as possible, used Brasso on the aluminum bases, used isopropyl alcohol to remove all the paint, removed each button from the vinyl and scrubbed the hell out of everything. The end result was extremely good, beyond what I was expecting. The original table that goes with this set is exceedingly rare, so I gave up looking and decided to pair them with a Herman Miller Eames table (84' x 42' white laminate).
These chairs are commonly referred to as "Star Trek chairs" because they were used as part of the set design in the ST:TOS episodes "Spock's Brain" and "The Trouble With Tribbles".
