If you enjoy spending time outside, it's worth having a good set of patio furniture. You'll want to choose a set that's comfortable, suits your sense of style and is appropriate for the climate in your area.
Natural wicker and rattan are classic materials for patio furniture. They're conveniently lightweight, but they will weather when exposed to the elements. All-weather wicker, which is synthetic, looks like natural wicker but is durable and resistant to sun and rain.
Metal patio furniture is another option. Aluminum is fairly lightweight and corrosion-resistant, with a smooth finish. Steel is heavier and is generally treated to prevent rust, but if you have severe weather you may need to use a rust-retardant primer and paint. Wrought iron is the heaviest and strongest material for outdoor furniture, and it's durable and rust-resistant, though a rust-retardant primer and paint may be helpful. The major downside to metal furniture is that it can get hot in the sun.
Wood patio furniture can be elegant and comfortable. Cedar is lightweight and resistant to moisture and insects. Eucalyptus is mid-weight and naturally water-resistant. Teak is dense and hard, with high resistance to weather, insects and marring.
Whatever material you choose, you'll find great patio furniture for less at Walmart. Save money. Live better.
