The "Siah Rud" (Means: Black River) bench is made from the wood of a tree aged 350 to 400 years. This tree, located by a river named Siah Rud, has witnessed the passage of water and time for years. The design of the bench is inspired by this continuous flow, with its fluid form cascading down like a waterfall, transitioning into a geometric and modern structure. The balance between functionality and form was designed and crafted for an art exhibition in 2020.
