When selecting cushion fabrics for coastal outdoor seating, durability is key due to the harsh marine environment. Saltwater, UV rays, and high humidity can quickly degrade low-quality materials. Here are the top choices for long-lasting performance:

1. Solution-Dyed Acrylic (e.g., Sunbrella®) – Highly resistant to fading, mold, and saltwater, making it ideal for coastal areas.

2. Polyester with Olefin Weave – Offers excellent moisture resistance and dries quickly, reducing mildew risk.

3. Marine-Grade Vinyl – Waterproof and easy to clean, perfect for high-salt exposure.

4. Polypropylene (Outdoor Mesh) – UV-stable and breathable, ensuring comfort in humid climates.

5. Crypton® Fabric – Stain-resistant and engineered to repel moisture and odors.

For maximum longevity, opt for fabrics with UV inhibitors and mold-resistant treatments. Regular rinsing with fresh water also helps prevent salt buildup. Investing in high-quality materials ensures your outdoor seating remains comfortable and stylish despite coastal challenges.
