What Is a Self-Weight Activated Mechanism in Office Chairs?

How Does a Self-Weight Mechanism Work?

Unlike traditional mechanisms that require users to manually adjust tilt tension, a self-weight mechanism uses an internal balance system that reacts to body pressure.

When the user leans back:

• The mechanism senses body weight

• Reclining resistance increases or decreases automatically

• The chair remains stable and well-supported at any angle

This ensures a smooth, natural reclining experience for users of different weights.

Key Advantages of Self-Weight Activated Mechanisms

1. Automatic Comfort for Every User

No adjustments required. Whether the user is light or heavy, the chair adapts instantly, making it ideal for shared workspaces.

2. Simplified User Experience

With fewer adjustment controls, the chair is easier to use—perfect for offices where users prefer “sit-and-work” functionality.

3. Improved Ergonomic Support

The synchronized movement between seat and backrest encourages proper posture and reduces pressure on the spine during long working hours.

4. Reduced Misuse and Maintenance

Because users cannot overtighten or loosen the tilt tension incorrectly, the mechanism experiences less wear and fewer failures over time.
