Wooden benches are a classic statement for any porch or garden- but not all wooden benches are equally durable. Hardwood benches should be favored over softer woods. Some wooden benches, like teak, are rich in natural oils (which reduces warping) and others, such as cedar, are naturally insect-resistant. Keep in mind that all wooden benches should be sealed and treated, and they require far more upkeep than something like Polywood or weather-resistant metal. Still, if treated properly, you can enjoy a wooden bench outdoors.
