Outdoor chairs and sofas made from durable materials like aluminum alloy, poly lumber, rattan, and teak are the most long-lasting. These materials are weather resistant, which means they can withstand exposure to sun, rain, and wind. When shopping for outdoor furniture, look for sturdy frames and high-quality weather-resistant cushions. You’ll also want to consider the construction techniques and the type of hardware used. For example, solid brass hardware is resistant to rust and corrosion. However, even the most durable outdoor sofas and patio chairs will need proper maintenance to prevent signs of wear and tear. Cleaning your outdoor furniture regularly and storing it during harsh weather conditions can prolong its lifespan.
