## Common ground
All options are inflatable seats made from flexible, air-filled materials.
## Options at a glance
**3926.90 – Made of plastic material**
- **Defining trait:** Constructed primarily from synthetic plastic films (e.g., PVC, polyethylene).
- **Typical examples:** Inflatable pool floats, plastic lawn chairs, portable party seats.
- **Best fit when:** The seat is lightweight, often used outdoors or in water, and made from a non-rubber, flexible plastic sheet.
**4016.95 – Made of rubber**
- **Defining trait:** Manufactured using natural or synthetic rubber, typically more durable and elastic than plastic.
- **Typical examples:** Inflatable rubber rafts, heavy-duty work seats, industrial air cushions.
- **Best fit when:** The seat requires high durability, resistance to punctures, or use in rugged environments.
