The Vignelli Bench, designed by the Italian designer Massimo Vignelli (also designed the New York City Subway map, which is cool but unrelated) with his wife Lella, is a highly geometric form that is made of polyethylene, and pretty much as straightforward as a bench can be. I think this works well with things with texture, pattern, color. It's priced well, clean lines, and it's available in all different colors-- green yellow, pink. I personally don't love the primary colors, but some people do, and I respect that.
