Metal Swivel Office Chair

Metal swivel office chairs typically feature an aluminum alloy five-star base design, equipped with swivel and height-adjustment functions, and come with caster feet, making them a common type of seating in modern office settings.

1. Footrest Structure of Metal Swivel Office Chairs

One of the core components of a metal swivel office chair is the footrest, which is commonly made of aluminum alloy or steel. Aluminum alloy five-star bases are widely used due to their lightweight, corrosion resistance, and strong load-bearing capacity. For example, the "Dagong Stool Five-Foot Office Chair Swivel Chair Height-Adjustment Chair" adopts a design that combines injection-molded nylon five-star casters with a steel foot base, ensuring both stability and enhanced mobility flexibility. Additionally, some products feature a "five-claw foot chassis" structure, which distributes pressure through the five claws, enhancing the overall balance of the chair and making it suitable for prolonged office use.

2. Caster Function and Material

Casters are a key component of metal swivel office chairs, directly affecting the user experience. Common caster materials include nylon and polyurethane, which are known for their wear resistance, quiet operation, and smooth rolling. For instance, some products are labeled as "direct-supply office chair feet swivel chair horseshoe foot aluminum alloy five-star base casters," indicating an integrated design of casters and footrest that allows for 360-degree rotation, facilitating free movement within the office area. The installation method for casters is usually snap-on, where they can be removed by prying at the connection point between the wheel and the footrest with needle-nose pliers, and installed by aligning with the slot and pressing firmly.

3. Height Adjustment and Swivel Function

Metal swivel office chairs are generally equipped with pneumatic height-adjustment rods, supporting height adjustments to accommodate users of different heights or desk heights. For example, the "Dagong Stool Five-Foot Office Chair" achieves stepless height adjustment through a pneumatic rod, with operation as simple as lightly pressing the adjustment handle beneath the seat. The swivel function is realized through a bearing at the center of the footrest, allowing users to easily turn without moving the entire chair, thereby improving office efficiency.

4. Maintenance and Repair

After prolonged use, casters may experience reduced rotation due to dust or wear. In such cases, refer to the repair guide: use needle-nose pliers to pry open the connection point between the wheel and the footrest, remove the wheel to clean internal debris or replace it with a new one; if the footrest bearing is stuck, apply lubricating oil for maintenance. Regularly check the seal of the pneumatic rod to prevent air leakage that could lead to height-adjustment failure.
