Caster Wheel Office Chair

The caster wheel office chair is an office seat equipped with rotation and height adjustment functions, belonging to the category of office supplies. The following provides a detailed introduction from five aspects: structure, classification, design, cleaning, and price.

Core Structure
The core components of a caster wheel office chair include the seat cushion, backrest, five-star base, casters, and pneumatic height adjustment system. The pneumatic rod achieves height adjustment through compressed air, allowing users to adjust the seat height according to their needs to match the desk height. The elastic support frame, in conjunction with the casters, supports 360-degree rotation and reduces vibrations during movement through cushioning design. Some high-end models are also equipped with a mobility locking device to fix the seat position and prevent sliding.

Product Classification
Office swivel chairs are divided into three series based on usage scenarios and functions:

1. Executive Chairs: These feature a high backrest design (usually exceeding 120cm), standard adjustable armrests and headrests, suitable for long-term office work by management personnel;
2. Mid-Back Chairs: The backrest height is approximately 90-120cm, with fixed or simply adjustable armrests, balancing comfort and cost;
3. Staff Chairs: These have a low backrest (below 90cm) and no armrests, occupying less space and suitable for dense placement in open office areas.

Ergonomic Design
Modern caster wheel chairs maintain the natural curvature of the human body through adjustable components:

• Lumbar Support: Most models are equipped with adjustable lumbar supports that can be moved up/down or forward/backward to support the 3rd to 5th lumbar vertebrae;
• Armrests: Support height and angle adjustments to reduce shoulder fatigue;
• Headrest: High-end models are equipped with rotatable headrests to support the cervical spine and prevent strain.
  These designs expand their applicable scenarios to home study, medical rehabilitation, and other fields.

Cleaning and Maintenance Solutions
Three solutions are provided for common problems:

1. Hair Removal: Use small scissors to cut along the groove of the wheels to remove tangled hair, avoiding direct pulling that may damage the bearings;
2. Dirt Cleaning: Moisten a used facial towel and let it air dry. Wrap the凹凸面 (textured side) around the wheels and secure with a rubber band, then clean by moving the chair back and forth;
3. Preventive Measures: Wrap the edges of the wheels with invisible tape to form a physical barrier and reduce dirt contact with the floor.

Price Range
The prices of basic home office chairs are concentrated in the range of 60.86-220.16 yuan, with price differentiation due to functional differences:

• Ordinary staff chairs: 80-150 yuan
• Mid-back chairs with lumbar support: 150-300 yuan
• Ergonomic chairs/gaming chairs: 500 yuan and above
  High-end models use imported pneumatic rods, breathable mesh fabrics, and other materials, with prices reaching over 2000 yuan.
