The Kurinoki Semi Armchair Sangyo is made from Japanese chestnut wood, known for its durability and unique grain. The chair features a gently curved backrest that provides lumbar support and a seat that rises toward the rear to stabilize the pelvis, ensuring comfort during long sitting sessions. The semi-arm design offers a place to rest your arms without restricting movement. Over time, the chestnut wood's tannins cause its color to deepen, adding character to the piece. Natural details like knots and wavy grain patterns further enhance its distinct look.
