Bench
From Nookipedia, the Animal Crossing wiki
The bench is a landscape feature introduced in Animal Crossing: New Leaf. It serves the same purpose as a bench in a house, though it is outside. Villagers can be found sitting on them, and a player can also sit on them. Like the ones in a house, two people can sit on them at once. In the trailer released about AC3DS, Punchy and the player are sharing just one of several benches scattered about town.
