Functional Angles of Office Chairs

Office chairs feature a variety of functional designs from the perspective of functionality, including recline adjustment, lumbar support adjustment, seat depth adjustment, armrest adjustment, headrest adjustment, and footrests.

In terms of recline adjustment functions, there are diverse adjustment mechanisms. The lever adjustment system is common, usually located beneath the seat near the right or left side. By pulling or pushing the lever, the lock is released, the recline angle is adjusted, and then locked again. The knob adjustment system has the knob mostly positioned near the central lower part of the seat close to the support column, allowing for the adjustment of recline tension and angle. The pneumatic adjustment system has the pneumatic lever arranged together with the height adjustment lever. By pushing in different directions, the recline is adjusted, providing a smooth adjustment experience. There are also considerations for choosing the recline angle. When focusing on work, a smaller recline angle is selected to maintain a vertical or slightly forward-leaning posture. For relaxation and thinking, a larger recline angle is chosen. After working for a long time, appropriate recline can relax the back muscles and promote blood circulation. For example, the Henglin L700 series office gaming ergonomic chair supports four-level recline up to 135° (with locking function). There are also office chairs with a large range of backrest adjustment, supporting stepless adjustment from 95 degrees to 160 degrees.

For the lumbar support adjustment function, turning the black knob on the side of the chair allows for free adjustment of the lumbar support height. The lumbar support can be adjusted by up to 6 centimeters, enabling adjustments according to personal habits. For example, adjusting it to about 4 centimeters provides a stronger sense of fit for the waist, reducing the likelihood of waist soreness after sitting for a long time. The Henglin L700 series features dual independent lumbar and back support, supporting 4-centimeter vertical adjustment with a very smooth operation. At the same time, the lumbar support part also supports about 3 centimeters of buffer rebound and can rotate slightly by about 10° to the left and right.

The seat depth adjustment function is available on some office chairs. For example, some office chairs have a 5-centimeter cushion depth adjustment, allowing for more sitting postures. The Henglin L700 series supports 4-centimeter adjustable seat depth.

For the armrest adjustment function, high-end ergonomic chairs offer rich armrest adjustment functions. For example, the Henglin L700 series adopts a dual-axis 5D enlarged and widened design, supporting 360° rotation, 7-centimeter vertical lifting, and 4-centimeter forward and backward movement.

In terms of the headrest adjustment function, some office chairs have adjustable headrests. For example, the Henglin L700 series is equipped with a dual-axis six-way adjustable headrest. The combination of the dual joints provides an adjustment range of up to 106°, and the vertical lifting can reach up to 13.5 centimeters, accommodating various heights and sitting postures.

For the footrest function, some office chairs come with footrests. For example, some office chairs can directly pull out the footrest to activate a 160-degree flat-lying mode. The high-end version of the Henglin L700 series comes with a built-in hidden footrest that can be pulled out for use.
