Herman Miller chairs Know that really comfortable chair in the office you keep hoping to snag when the guy who's been there since the tech boom leaves? It's likely Herman Miller's Aeron. Much like the other iconic American products on this list, the Aeron's beauty stemmed from its design. Folks in the design community love it so much that it's found a place at the Museum of Modern Design in New York. Herman Miller ( MLHR) cranks out its chairs at two factories in Western Michigan and produces about four a minute. While nearly three-quarters of those sales occur in the U.S., Herman Miller exports its chairs to another 140 countries.
