Specify the loading conditions

Chair backs, armrests and seat supports experience different loads. Consider part location, load direction and cyclic-use conditions.

Assess structure and materials together

Evaluate reinforcement, wall thickness, ribs and assembly together. A single mechanical property cannot replace structural validation.

Validate throughout the service life

Check appearance, dimensions and relevant properties during trials. Add impact, fatigue and environmental validation as required by the project.

This article provides general material-selection guidance, not a technical data sheet. Confirm the grade, operating conditions and validation requirements for your project.
