Can polyester fabric outdoor chairs be used in sauna areas?

Polyester fabric outdoor chairs are popular for their durability and weather resistance, but are they suitable for sauna areas? Saunas expose furniture to extreme heat and humidity, which can degrade materials not designed for such conditions. While polyester is resilient, it may not withstand prolonged exposure to high temperatures, potentially leading to fading, warping, or even melting. For sauna use, it's safer to opt for materials like teak or specially treated fabrics that can handle heat and moisture. Always check manufacturer guidelines before using polyester chairs in saunas to ensure safety and longevity.
