Office chairs have been certified by BIFMA and SGS and have passed a static pressure test of 1136 kg. The chair can support a weight of up to 150 kg. The seat cushion, covered with a full sponge mesh, is durable and can be used for a long time. The multidimensional, freely rotating headrest protects the cervical vertebrae. Adjustable PU armrests, a 10 cm height-adjustable gas lift, and 360° rotation provide flexibility and are suitable for your office environment. The tilt function with position lock and 120° backrest adjustment ensures your office relaxation. With the W-shaped design, you can always sit in the center of the chair and receive the necessary support from the backrest. The front edge of the seat resembles a waterfall, reducing pressure on the thighs as much as possible while sitting. The ergonomic design is based on a human dynamic digital model. You can also adjust the seat height and flexibly position the backrest and armrests to achieve the best posture. Anyone can install this chair in just a few steps using the manual.
