We don't use the words "hella cool!" all that often, but then again, we don't often stumble across chairs made out of NYC traffic signs. Uncommon Goods has the chair, made by John Carter. Sure, it's $2700, and probably weighs a couple of hundred pounds, but get a load of the features:
The chair comes complete with all the genuine scuffs and stains of its New York City roots, and the seating surfaces have been reglazed with one inch-thick polished resin, cushioned with felt suspension. The chair plugs into a standard 115V AC outlet, and the standard bulbs (included) are replaceable. Handmade in New York City.
Aspiring furniture designers, please take note. We'd like to see a whole line of this furniture-- desks made out of traffic signs, beds made out of park benches, toilets made out of public water fountains. Please get to work.
