Office Chair Accessories - Feet

There are various types of office chair accessories - feet, and their prices vary depending on the material and function. Common types include anti-slip foot pads, adjustable feet, and universal caster wheels. Modern office chairs mainly feature a five-star base structure.

I. Common Types of Foot Accessories and Their Prices

1. Anti-slip Foot Pad Types

   • Basic Anti-slip Type: For example, the "Furniture Plastic Foot Nails, Thickened Nylon Foot Nails, Anti-slip Nails" are made of plastic or nylon. They prevent chair sliding by increasing friction and cost about ¥0.35. Another option, the "Office Desk and Chair Anti-slip and Anti-tipping Foot Pads" with a flat design, are suitable for internet cafe chairs and swivel chairs, with prices as low as ¥0.13.
   • Anti-forward-tilt and Wear-resistant Type: The "25 Office Chair Anti-forward-tilt Foot Pads" are designed to address the issue of chair forward tilting. Made of wear-resistant plastic, they enhance anti-slip functionality and cost about ¥0.4.

2. Adjustable Foot Types

   • Screw-rod Adjustment Type: For example, the "48mm Rubber Foot Pad Adjustment Feet" achieve fine height adjustment through a screw-rod structure. They are suitable for stools, computer cases, and other scenarios, and also have shock-absorbing functions, costing about ¥0.72. Another option, the "British 3/8-16 Thread Heavy-duty Furniture Adjustable Leveling Feet" with a metal thread design, have stronger load-bearing capacity and cost about ¥1.66.

3. Universal Caster Wheel Types

   • Hidden Universal Wheels: For example, the "Silent Embedded Invisible Small Caster Wheels" with a diameter of 48mm are suitable for swivel chairs and office furniture. They can be installed hidden, move flexibly, and are silent, costing about ¥1.36.

II. The Mainstream Structure of Modern Office Chairs: Five-star Base

The five-star base is the core component of modern office chairs, featuring a five-claw shape. There are three types of materials:

• Nylon with Fiber: The most common type. By adding fiber, the strength of nylon is enhanced, combining light weight and durability. It is suitable for gaming chairs, adjustable seats, and other scenarios.
• Metal Material: For example, aluminum alloy or steel five-star bases have higher load-bearing capacity but are heavier. They are mostly used in high-end office chairs.
• Plastic Material: It has a lower cost but weaker strength and durability, gradually being replaced by nylon with fiber.

The design of the five-star base directly affects the chair's lifespan and transportation efficiency. A reasonable claw shape structure can disperse pressure and avoid local deformation. The production process (such as injection molding accuracy and uniform fiber distribution) determines its impact resistance. In addition, some five-star bases integrate silent wheels or adjustable feet designs to further expand functions.

III. Purchase Recommendations

• Anti-slip Requirements: Prioritize choosing foot pads made of rubber or silicone materials, which have a higher friction coefficient.
• Height Adjustment: Screw-rod adjustment feet are suitable for uneven floor scenarios, but regular inspection of tightness is required.
• Mobility Requirements: For universal wheels, pay attention to the load-bearing parameters (such as a load-bearing capacity of ≥50kg per wheel) to avoid deformation and jamming.
• Five-star Base Material: Nylon with fiber offers the best cost-effectiveness, while metal materials are suitable for heavy-load scenarios.
