I really love this outdoor 'Wimbledon Chair' that Nola presented at the Stockholm Furniture Fair 2009. Nola is a Swedish company that excels in creating funky and functional designs for the urban environment.
I would even have the steel square 'Wimbledon Chair' in my home with a nice sheepskin cushion. I love the strong graphic look of the grid combined with the round bend of the metal for seating. The chair comes in bright green and red; it is part of a series called 'Concrete Things' created by Komplot, a Danish design company.
