What are the ergonomic considerations for armrest design in WPC armchairs?

When designing armrests for WPC (Wood-Plastic Composite) armchairs, ergonomic considerations are crucial to ensure comfort, support, and long-term usability. Here are the key factors to consider:

1. Height and Width: The armrests should align with the user’s natural elbow height when seated, typically 7-9 inches above the seat. A width of 2-3 inches provides adequate support without restricting movement.

2. Shape and Contouring: Curved or slightly padded armrests reduce pressure on the elbows and forearms, promoting better blood circulation and reducing fatigue.

3. Material and Texture: WPC armrests should have a smooth, non-slip surface to prevent discomfort during prolonged use. Soft coatings or rounded edges enhance user comfort.

4. Adjustability: For versatility, consider adjustable armrests to accommodate users of different heights and seating preferences.

5. Posture Support: Properly designed armrests encourage upright posture, reducing strain on the shoulders and lower back.

By prioritizing these ergonomic principles, WPC armchairs can offer superior comfort and functionality for diverse users.
