## Common ground
All options refer to furniture gliders—components that allow smooth, quiet movement of chairs or stools.
## Options at a glance
**3919.90 – Made of plastic**
- **Defining trait:** Constructed primarily from synthetic plastic materials.
- **Typical examples:** Plastic chair glides with rubberized tips, molded polypropylene feet.
- **Best fit when:** The glider is rigid, lightweight, and made entirely or mostly from plastic (e.g., for office chairs or budget furniture).
**6307.90 – Made of textile**
- **Defining trait:** Composed mainly of woven or non-woven fabric materials.
- **Typical examples:** Fabric-covered glides with felt or cloth pads, soft-textured chair feet.
- **Best fit when:** The glider uses fabric as the primary contact surface (e.g., for decorative or soft-touch furniture like sofas or vintage chairs).
## Key differences
| Feature | 3919.90 (Plastic) | 6307.90 (Textile) |
|------------------|--------------------------|----------------------------|
| Material base | Synthetic plastic | Woven/non-woven fabric |
| Durability | High, wear-resistant | Moderate, may degrade |
| Noise level | Low to very low | Very low (soft contact) |
| Common use | Office, industrial chairs| Decorative, home furniture |
## How to choose
- Is the glider made mostly of rigid plastic? → 3919.90
- Does it have a fabric or felt surface as the main contact point? → 6307.90
## Overlaps & pitfalls
A product with a plastic base and fabric top (e.g., a plastic foot with a cloth pad) could fit both. In such cases, prioritize the **primary material in contact with the floor**—if fabric touches the floor, use 6307.90; if plastic does, use 3919.90. The wording is clear but depends on actual construction
