The scientifically inclined backrest reduces lower back pressure and offers strong support to your spine. The frame is crafted from imported solid ash wood, known for its smooth grain and hard, dense texture. The chair utilizes traditional mortise and tenon joints and is finished with eco-friendly open paint, ensuring no unpleasant odors. Both the seat and backrest are filled with thick, high-resilience foam, allowing you to stretch out and release pressure comfortably.
