In some areas, winter weather is a factor that cannot be ignored and outdoor furniture must withstand wind, rain, and infrequent sun exposure. Rain can warp wood, corrode or rust metal, and mold fabrics. The sun, on the other hand, can crack wood and lighten the color on plastics or fabrics.
When it comes to durability, the general rules are as follows:
• Teak is better than pine.
• Cast aluminum is better than steel and easier to maintain than iron.
• UV-treated polyester is better than cotton.
• High-quality synthetic rattan or wicker is better outdoors than real one. It hardly needs any maintenance.
