Office Chair Caster Accessories

Office chair caster accessories come in a variety of types, with prices varying based on specifications and functions. Common products include fixed casters and universal wheel fixing pads, with prices ranging from a few jiao to several dozen yuan.

I. Types and Prices of Basic Caster Accessories

1. Fixed Casters
   Fixed casters are common fixed-wheel accessories for office chairs, typically used in scenarios where the chair needs to maintain a stable direction. For example, the 1.5-inch fixed guide wheel (fixed caster) features a fat wheel design, mostly made of metal or high-strength plastic, with strong load-bearing capacity, suitable for heavier office chairs or furniture, priced at ¥1.12 per piece. Another 1-inch fixed white PP wheel is made of nylon, lighter in weight, suitable for light furniture or cabinets, priced at ¥0.88 per piece.

2. Anti-Slip Fixed Wheels
   Some caster accessories are designed for anti-slip needs, such as the 2-inch open-mouth swivel chair fixed wheel, which adopts a snap-ring insert structure, preventing the wheel from rotating after installation to stop the chair from sliding. Such accessories are typically used in scenarios requiring a fixed position (e.g., beside conference tables), but the price is not explicitly mentioned in the reference information.

II. Types and Prices of Functional Accessories

1. Universal Wheel Fixing Pads
   Universal wheel fixing pads are accessories used to restrict the sliding of swivel chair universal wheels, achieving a fixing effect by increasing friction or physical blocking. For example, the factory-direct model uses silent anti-slip materials, compatible with various computer chair bases, priced at ¥29.93 per set; another clip-on fixing pad is cheaper, priced at ¥1.87 per piece, suitable for temporary fixing or lightweight chairs.

2. Caster Fixers
   Caster fixers are usually used in conjunction with universal wheels, restricting wheel rotation through clamping or snap-fit structures. Some products integrate anti-slip pad functions, reducing noise when the chair moves and protecting the floor surface. The prices of such accessories vary greatly depending on the material and design complexity, requiring selection based on specific models.

III. Purchase Recommendations

1. Choose Based on Usage Scenarios
   If the chair needs to be fixed for a long time (e.g., in front of a desk), prioritize fixed casters or anti-slip fixed wheels; if occasional fixing is needed (e.g., in conference scenarios), universal wheel fixing pads are more flexible.

2. Pay Attention to Load-Bearing Capacity and Material
   Heavy-duty office chairs require casters made of metal or thickened plastic, while light chairs can choose nylon or PP materials to reduce costs.

3. Check Compatibility
   Before purchasing, confirm whether the insert diameter and wheel size of the casters or fixing pads match the chair base to avoid installation difficulties.

The diversity of office chair caster accessories can meet different needs, and reasonable selection can enhance the user experience and extend the lifespan of furniture.
