Office chairs are designed to support the natural curve of the user's spine. This is important because prolonged sitting can lead to poor spinal posture and increased stress on the lumbar and cervical spine. The main function of a pneumatic device is to allow quick and easy adjustment of the height of the chair and the tilt angle of the seat. An office chair of the right height ensures that the user's feet can rest smoothly on the floor and maintain a correct sitting posture.

• The material of this office chair is made of high quality premium mesh, which is non-irritating and very friendly to the user's skin. This mesh material is highly breathable. Under normal circumstances, sitting for long periods of time may cause the user's back and buttocks to sweat and sometimes feel uncomfortable and sticky. However, this mesh material provides good gas permeability, ensuring air circulation and keeping the body cool and dry.

The armrests of this office chair can be adjusted in multiple directions, such as tilting upward, downward, forward, backward, etc., enabling users to adjust the position and angle of the armrests according to their personal preferences and work needs. The headrest can be adjusted up and down according to the user's needs to accommodate different users' heights and neck needs. By adjusting the height of the headrest, users can find the most suitable position for their head support and reduce the pressure and fatigue of the neck.

The five rollers on the bottom make this office chair very easy to move around. Users can easily move it to different locations within the office, avoiding the hassle of having to stand up frequently to move or drag the chair around. By using a sturdy material to make the base, this office chair can withstand high loads and long-term use without being damaged. This ensures the safety and stability of the user while sitting in the chair.
