Dazu Office Chair Computer Chair

The Dazu office chair computer chair focuses on ergonomic design and functional adjustments to enhance long-term sitting comfort and healthy support. Its main features are as follows:

Backrest Design: Fits the Spinal Curve, Dynamically Supports the Lumbar Region

The backrest is designed based on research into the physiological load of human sitting postures, adopting a curved design with a recline angle and prominent lumbar support to mimic the natural 'S' shape of the spine, providing targeted support to the lumbar region and dispersing localized pressure. Some products feature precisely matched lumbar supports for the third and fourth lumbar segments or adjustable lumbar supports that can be adjusted in height and angle to accommodate differences in spinal length and curvature among users, achieving personalized alignment of support points. The elasticity and support hardness of the backrest material jointly determine the fit, with its curvature, elasticity, and zoning design forming a dynamic response system: when leaning back, it provides basic support while allowing moderate movement in the scapular region to prevent muscle stiffness.

Seat Cushion Design: Balances Pressure and Support, Protects Blood Circulation

The seat cushion uses a composite structure of materials with different densities, employing high-density materials in the ischial load-bearing areas (such as the buttocks and upper thighs) to provide stable support and prevent pelvic posterior tilt; the surrounding areas use low-density materials to soften and relieve thigh pressure, preventing excessive sinking of the ischial bones that could alter pelvic angle or compress the sciatic nerve and blood vessels. The density gradient distribution of the filling further disperses pressure on the thighs and buttocks, ensuring smooth blood circulation during prolonged sitting.

Adjustment Functions: Multi-Dimensional Adaptation to Different Needs

• Seat Height Adjustment: Achieved through a gas lift or mechanical screw lift column, ensuring the user's feet are flat on the ground and the thighs are parallel to the ground, reducing leg pressure.
• Backrest Recline Angle and Armrest Height Adjustment: Allows users to adjust support points according to tasks (such as reclining for rest or leaning forward for work), dynamically changing postures to avoid continuous tension in a single muscle group. Some high-end products are equipped with gas lift and recline damping adjustment, enabling smooth transitions between work postures and maintaining continuous lumbar and back support.
• Adjustable Lumbar Support: Independently adjustable in height or angle to fit the spinal characteristics of users with different body types.

Upholstery and Filling: Balances Comfort and Durability

• Upholstery: Breathable mesh fabric promotes heat dissipation and moisture wicking, reducing a stuffy feeling; leather or velvet offers different tactile sensations and visual styles.
• Filling: The anti-deformation ability of high-resilience foam or molded cotton directly affects the long-term shape retention and support effect of the chair, ensuring it remains supportive and does not sag after prolonged use.

Other Designs: Detail Optimization for a Healthy Experience

• Headrest Adjustment: Adjustable in height and angle to keep the cervical and thoracic spine in a straight alignment, reducing static load on the posterior neck muscles.
• 360-Degree Rotation and Lifting: Achieved through a gas lift and 'chassis' components (including bearings) for smooth displacement and free rotation, reducing shear forces on the lumbar spine from twisting the upper body.
• Adjustable Armrests: Coordinate with seat height adjustments to provide forearm support, relieve shoulder and neck pressure, and enhance adaptability to different body types and work habits.
