Bolt Series is a minimal furniture collection created by Seoul-based designers Hyunseog Oh and Sangmyung Yu of niceworkshop. In the midst of being rapidly made and used, there are things that people miss without consciousness. Bolt series focus on what people actually miss. Full threaded bolts are using as ceiling materials in the construction site and are being discarded indiscreetly. So we suggest different possibilities and use of full threaded bolts. The studio wanted to find out the new possibilities of utilization of full threaded bolts focusing on its use as a flexible material. The table focuses on spatiality in its intention of controlling the space. The space which is made of emptiness performs the role as service station and shapes the space perception.
