How do manufacturers test fabric outdoor chairs for pucker resistance?

Manufacturers test fabric outdoor chairs for pucker resistance to ensure durability and longevity. The process typically involves subjecting the chairs to repeated stress, such as sitting and movement simulations, to evaluate how well the fabric resists wrinkling or puckering. Advanced testing may include exposure to varying weather conditions, like humidity and UV rays, to assess long-term performance. Quality control teams also inspect stitching and fabric tension to identify potential weak points. These rigorous tests help guarantee that outdoor chairs remain comfortable and visually appealing over time.
