Lockable Tilt Function - The chair's backrest can be reclined back and locked, which helps relieve stress on the lower back muscles and relax the lumbar area, allowing you to relax from heavy work. The tilt range is 90 degrees to 135 degrees.

Dynamic Lumbar Support & Height Adjustable - This ergonomic office chair supports the natural curve of the spine and keeps you in good posture. Pneumatic controls make it easier to raise or lower the seat, which allows you to pick the appropriate level for long-term comfort. It is perfect for the office, bedroom, study room, conference room, reception room, and gaming room.

Extremely Good Air Permeability - The comfortable seat cushion is constructed using premium mesh. The breathable mesh allows increased air circulation for a roller-fitted experience, while also retaining its shape for longer. Also, the mesh is non-irritant and soft even for sensitive skin.

Ergonomic 3D Armrests & Adjustable Headrest - The 3D adjustable armrests can go forwards, back, sideways, up, and down, which helps reduce the tension in the upper body and allow the shoulders and arms to relax. Besides, the headrest adjusts up and down and angles up and down to support the neck.
