People usually have to buy tickets to visit a public park, but there are few who do not believe in paying for tickets and just sneak through the fences illegitimately. To check those illicit visitors, designer Fabian Brunsing has come up with a crazy though creative park bench that integrates retractable metal spikes. Dubbed the “PAY & SIT,” the private park bench as depicted by its name requires a half a Euro coin, to be inserted in the coin slot, to remove the metal spikes from seating surface to rest visitors in comfort.
