Office Chair Upgrade
Office chair upgrades can be carried out in multiple aspects such as support, comfort, material, and functional adjustability. Here are some upgrade cases and their features:

Support Upgrades:
The Henglin Nixizhe upgraded version is equipped with an independent 3D dynamic lumbar support that allows for 6cm of vertical adjustment and 15ยฐ of lateral rotation. It can adaptively support the lower back whether sitting upright or reclining, effectively relieving lower back pressure. The Guquan C031 features an S-shaped backrest that fits the spinal curve, and its concentrated lumbar heating function further enhances support comfort. The Qingxian Dynamic Ergonomic Chair S1 has a backrest, neck pillow, seat cushion, and armrests that adjust synchronously with posture changes, ensuring continuous support and avoiding interruptions in operation.
Comfort Upgrades:
The mesh fabric of the Henglin Nixizhe upgraded version offers better breathability than the previous model, and its 9cm thickened and widened seat cushion improves hip comfort. The Guquan C031 has a thickened double-layer cushion, while the Guquan C533 is filled with plush cotton and sponge particles, providing good resilience. The steel office chair features a soft sponge seat cushion with excellent resilience. The Qingxian Dynamic Ergonomic Chair S1 uses zoned sponge, with different hardness levels at different pressure points, balancing support and a wrapped feel.
Material Upgrades:
The five-star base of the Henglin Nixizhe upgraded version has been upgraded from nylon to a heavy-duty steel base, paired with PU silent wheels for more stable and quiet movement. The steel office chair adopts a steel frame structure throughout, solving the problems of easy damage and glue separation in wooden chairs, with a simple appearance and easy cleaning. The Guquan series air rods have all passed four-level explosion-proof certification, enhancing safety.
Functional Adjustability Upgrades:
The chassis of the Henglin Nixizhe upgraded version supports a 130ยฐ recline with four-level locking and a hidden footrest design suitable forๅไผ (noon breaks). The Guquan C031 has a maximum recline angle of 160ยฐ and supports 6cm of height adjustment. The Guquan C533 supports a large recline angle of 90ยฐ-160ยฐ, equipped with a rocking function and a lever design for easy adjustment of the recline angle and seat height. The Qingxian Dynamic Ergonomic Chair S1 allows for adjustment of the armrest height and seat height, with the backrest offering three angles of 115ยฐ (work), 135ยฐ (entertainment), and 160ยฐ (rest). The neck pillow and footrest are also adjustable, meeting the needs of multiple scenarios.
