That's an excellent question! The material of your outdoor bench armrests makes a huge difference in comfort, durability, and overall style. Let's break down the most common and reliable materials you'll find.
First, metal armrests, particularly those made from powder-coated aluminum or steel, are top contenders. The powder coating is key—it provides a thick, durable finish that resists chipping, rust, and UV rays. They are incredibly sturdy, easy to clean with just a damp cloth, and perfect for modern or industrial-style settings.
For a warmer, natural look, hardwoods like teak, eucalyptus, or shorea are fantastic choices. These dense woods naturally contain oils that resist moisture, rot, and insects. When properly treated with a sealant, they develop a beautiful silvery-gray patina over time while remaining strong and supportive.
Another popular option is synthetic rattan or wicker, typically woven over an aluminum frame. This material is all-weather resistant, won't fade or crack in the sun, and is surprisingly comfortable. The armrests are smooth and offer a relaxed, resort-like feel that's perfect for lounging.
Some high-end benches feature armrests made from polyethylene (PE) lumber. This recycled plastic material mimics the look of wood but requires zero maintenance. It won't splinter, rot, or need painting, making it a truly "set it and forget it" option.
Ultimately, the best material depends on your climate and desired upkeep. Metals and synthetics offer maximum weather resistance, while treated hardwoods provide timeless, natural beauty. Always look for quality construction where the armrest is securely integrated into the frame for years of relaxed enjoyment.
