Office Chair Swivel Lift

The lifting function of office swivel chairs is achieved through specific mechanical structures, and the lifting adjustment methods may vary among different models of swivel chairs.

Lifting Mechanism

The lifting function of office swivel chairs mainly relies on gas springs or hydraulic cylinders. A gas spring is filled with high-pressure nitrogen gas inside, and the lifting of the chair is achieved through the up-and-down movement of the piston. When a person sits on the chair and operates the lifting control device, such as a lever or button, the gas pressure inside the gas spring changes, thereby pushing the chair up or down. A hydraulic cylinder, on the other hand, utilizes the principle of liquid pressure transmission and achieves lifting by controlling the flow of hydraulic oil. However, gas springs are more commonly used in office swivel chairs.

Adjustment Methods

• Jingdong Jingzao Z5 Pro Ergonomic Chair: This chair has a 50mm adjustable backrest. The adjustment method usually involves placing an adjustment button or lever on the side or bottom of the backrest. The user simply needs to press or pull the device and apply a certain amount of force as needed to move the backrest up and down within a 50mm range. This meets the needs of users of different heights for backrest height and provides better support for the back.
• Saigu Apollo X3 Ergonomic Chair: It allows for lumbar support lifting and backrest height adjustment. For lumbar support lifting, a dedicated adjustment mechanism is usually placed on the lumbar support area, which can be a knob-type or slide-rail type. If it is a knob-type, the user rotates the knob to control the up-and-down movement of the lumbar support; if it is a slide-rail type, the user can manually push the lumbar support to slide on the slide rail to achieve lifting. The method for backrest height adjustment is similar to that of the Jingdong Jingzao Z5 Pro, which is completed by operating the adjustment device on the side of the backrest.

Precautions

When using the lifting function of an office swivel chair, be careful not to apply excessive force or operate it too quickly to avoid damaging the gas spring or the adjustment mechanism. At the same time, regularly check the tightness of the gas spring. If you find that the chair does not lift smoothly or there is a gas leak, stop using it immediately and contact a professional for repair or replacement to ensure safety during use.
