Office Chair Caster Accessories

Office chair caster accessories come in various types, with prices varying based on specifications and materials. When selecting, it is recommended to prioritize PU wheels for a balance of stability and floor protection. Here is a detailed analysis:

I. Common Types and Price Ranges
According to market information, office chair caster accessories are mainly divided into two categories: fixed wheels and swivel wheels, with prices significantly influenced by size, material, and functionality.

1. Fixed Wheels:

   • 2-inch fixed casters for swivel chairs (snap-in foot pads with anti-slip felt pads): ¥1.71.
   • Reinforced solid fixed casters for swivel chairs (snap-in foot pads): ¥2.0.
     Fixed wheels are suitable for scenarios requiring stable support, such as fixed workstations or carpeted environments, and are relatively low in price.

2. Swivel Wheels:

   • 1.5-inch/2-inch flat swivel wheels (with brake function): ¥0.95.
   • Swivel wheel snap-in casters (1.5-inch/2-inch snap design): ¥3.6.
   • Zinc alloy flat furniture casters (1.5-inch plywood with brake, 2-inch high-end silent swivel wheels): ¥6.0.
     Swivel wheels offer high flexibility and are suitable for scenarios requiring frequent movement. Prices vary significantly based on material (such as zinc alloy) and functionality (such as silence and braking).

II. Material Selection Recommendations

1. Prioritize PU Wheels:
   PU (polyurethane) wheels are characterized by high elasticity, strong wear resistance, and quiet movement, making them particularly suitable for wooden floor households. Their soft surface reduces friction with the floor, preventing scratches or noise, and offers lower long-term usage costs.
2. Comparison with Other Materials:
   • Nylon wheels: High hardness and strong load-bearing capacity, but generate significant noise during movement and may damage wooden floors.
   • Rubber wheels: Good silence performance, but weaker wear resistance than PU wheels and prone to aging with long-term use.
   • Metal wheels: Outstanding load-bearing capacity, but heavy and noisy, suitable only for industrial environments.

III. Functionality for Different Scenarios

1. Brake Function:
   If the office chair needs to be fixed in place (such as in meeting scenarios), swivel wheels with brakes can be chosen to prevent accidental sliding.
2. Silence Requirement:
   For households or open offices, it is recommended to choose silent designs (such as zinc alloy silent swivel wheels) to reduce noise interference.
3. Load-Bearing Requirement:
   Choose wheel specifications based on the weight of the chair. Generally, 2-inch wheels offer better load-bearing capacity than 1.5-inch wheels, and solid designs are more durable than hollow ones.

Summary: When purchasing, consider the three elements of size, material, and functionality comprehensively. Prioritize meeting the needs for floor protection (PU wheels), silence, and load-bearing capacity, and then choose cost-effective products based on the budget.
