Office Chair Foot Dimensions

The dimensions of office chair feet vary depending on standards, types, and purposes. Common specifications are as follows:

1. Chair Foot Dimensions under the EN1335 Standard

According to the EN 1335‑1:2020 standard, the maximum radius s of the chair feet for all types of office chairs (Type Ax, Type A, Type B, Type C) is 415mm. This dimensional requirement applies to all office chairs that comply with the standard, regardless of whether they are equipped with casters. If the chair has casters, they should be adjusted to align with the radius direction to ensure stability and safety during use. This standard primarily addresses the overall coverage area of the chair feet rather than the dimensions of specific components, making it suitable for most general office scenarios.

2. Common Specifications for Nylon Five-Star Feet

Nylon five-star feet are a common type of chair foot used in office chairs, with dimensions varying based on product positioning:

• General Diameter Specifications: Ordinary office chairs typically accommodate five-star feet with a diameter of around 600mm, suitable for daily office needs. Executive chairs or high-level management chairs, which require higher load-bearing capacity and stability, generally use five-star feet with a diameter of around 700mm.
• Examples of Special Product Dimensions: Some products, such as the "Xiyan 283032 Caster-Compatible Five-Star Foot Frame," have dimensions of 4.9cm in length × 4.9cm in width × 7.8cm in height, representing a compact design. Wider and thicker nylon five-star foot frames may have diameters close to or slightly exceeding 700mm, with specific thicknesses and widths requiring reference to the product manual to accommodate higher load-bearing capacities or special use scenarios.

3. Length of Five-Star Feet for Computer Chairs

Some sources mention that the length of five-star feet for computer chairs is generally 20 centimeters. This dimension likely refers to the extension length of a single leg of the five-star foot (from the center to the endpoint) rather than the overall diameter. It is important to note that such statements may vary depending on the product type or measurement method, and it is advisable to confirm with specific product parameters when making a purchase.

Summary

The selection of office chair foot dimensions should consider standard requirements, use scenarios, and product positioning. The EN1335 standard specifies the maximum radius range for chair feet, while nylon five-star feet differentiate between ordinary and high-end products through diameter. The length of five-star feet for computer chairs may vary due to design differences. When purchasing, it is recommended to prioritize referring to the product manual or consulting with the merchant to ensure that the dimensions match actual needs.
