Our office chair featured an ergonomic design, a breathable s-shaped screen mesh back that follows the curve of your spine to give you more comfort, and built-in lumbar support to support your lower back and reduce back pain. This task chair is made of a high-resilience sponge and breathable mesh cloth to provide more comfort. Flip-up padded armrests to save more space when not in use. 360 degrees swivel design cooperates with wheels, a rockable backrest, and a height-adjustable seat can help you work much more efficiently. Customer-first is our original aspiration of us. No matter what problems you encounter during use, you can contact us. We will provide you with professional services on the product.
