When shopping for outdoor furniture it's important to choose pieces that are both weather-resistant and durable. Wicker is a good option (just make sure the wicker is "all weather", because if not, it will fade in the sunlight) and is particularly popular at beach houses or homes with British Colonial decor. Wicker is great because it can be painted any color (though white is most popular) and pairs well with colorful blankets or throw pillows.
