Korean designer Jiyoun Kim created 24 Dokkaebi stools as part of a larger art installation in the Hangang Art Park, near the Han River in Seoul. Four artists including Kim were selected to provide permanent works for the project, which was initially launched by the city’s government body. The task: devise original pieces that revolve around the theme of suim, Korean for “rest.”

Named after a playful goblin mentioned in Korean folk tales, the 24 cylindrical stools— one for each pine tree in the selected installation site—are made of mirror-polished stainless steel and measure 14 inches in diameter and 18 1⁄2 inches high. The tops are painted in eight nature-inspired gradient colors with a resilient matte clear coat. The stool’s mirrored surface captures reflections of the surrounding grass, trees, and sky, creating the illusion that the colored portion is floating in midair. “Just like Dokkaebi easily manipulating his appearance, these stools naturally immerse into the surrounding areas,” says Kim. “They will also transform according to the colors of the forest that change as the year passes.”
