Office Chair Foot Specifications

The specifications of office chair feet vary depending on the product type and usage scenario, as detailed below:

I. Common Diameter Range
The common diameter range for nylon five-star feet of office chairs is 600mm to 700mm. Regular office chairs typically accommodate five-star feet with a diameter of around 600mm, which can meet the load-bearing and stability requirements of daily office scenarios. For example, swivel chairs配套 (matching) regular office desks often use this size. Executive chairs or high-level management chairs, due to their larger seat sizes and higher load-bearing requirements, generally adopt five-star feet with a diameter of around 700mm, enhancing the overall structural stability by expanding the ground contact area and avoiding the risk of tipping due to center-of-gravity shift.

II. Examples of Special Product Sizes

1. Xiyan 283032 Caster-Matched Five-Star Foot Frame: With dimensions of 4.9 cm in length × 4.9 cm in width × 7.8 cm in height, it belongs to a small five-star foot design. Such products are typically used for lightweight office chairs or specific models of caster assemblies. Their compact structure saves space, but their load-bearing capacity is relatively limited. They must be strictly matched with the chair model to avoid breakage due to overload.
2. Widened and Thickened Nylon Five-Star Foot Frame: Although the specific dimensions of this product are not clearly indicated, its load-bearing performance is enhanced through a 'widened and thickened' design, making it suitable for scenarios involving heavier individuals or long-term high-load usage. Its diameter may approach or slightly exceed 700mm, and the thickness and width parameters should be referred to in the product manual to ensure compatibility with the seat, gas lift, and other components.

III. Characteristics of Office Chair Feet in Different Forms
Common office chair forms on the market include five-star foot swivel chairs, four-legged chairs, bow chairs, and high-stool chairs. Among them, five-star foot swivel chairs are the mainstream choice due to their large ground contact area and strong stability, especially suitable for scenarios requiring frequent movement or adjustment of sitting posture. Four-legged chairs have a smaller ground contact area and poorer stability, mostly used for short-term usage scenarios such as meetings or training sessions. Bow chairs and high-stool chairs, due to their special structures, require chair foot specifications to be determined according to specific designs and generally do not adopt standardized sizes.

IV. Characteristics of Chair Feet in Different Materials
The material of five-star foot chair feet directly affects their performance and applicable scenarios:

• Nylon Chair Feet: Wear-resistant, corrosion-resistant, high in strength, light in weight, and affordable. After high-strength treatment, their safety and sturdiness are guaranteed, making them a cost-effective choice.
• Steel Chair Feet: Higher in strength than nylon feet, but heavier in weight and higher in manufacturing cost. Their surfaces are usually electroplated for rust prevention, suitable for scenarios with extremely high load-bearing requirements.
• Aluminum Alloy Chair Feet: Corrosion-resistant, low in density, high in strength, and good in plasticity. They are the most expensive but have the best load-bearing performance and are environmentally friendly and recyclable, mostly used for mid-to-high-end office chairs or ergonomic chairs.
