What are the effects of prolonged compression on the shape of PVC outdoor chairs?
Prolonged compression can significantly alter the shape of PVC outdoor chairs, leading to permanent deformation over time. When PVC chairs are subjected to continuous weight or pressure, the plastic material may gradually lose its original form, resulting in sagging seats, bent legs, or warped backrests. Factors like temperature fluctuations and UV exposure can accelerate this process. To minimize deformation, it's advisable to store chairs properly during off-seasons, avoid excessive weight, and use chair covers for protection. Regular maintenance and choosing high-quality PVC chairs with reinforced frames can also extend their lifespan and preserve their shape.
