Choosing the right wood for your outdoor bench is crucial for longevity, aesthetics, and budget. The two most popular choices are pressure-treated lumber and cedar. Here’s a detailed, real-world comparison to help you decide.
Pressure-treated wood, typically Southern Yellow Pine, is infused with chemical preservatives under high pressure to resist rot, decay, and insect damage. It's the workhorse of outdoor construction—highly durable and the most affordable option. The main drawback is its appearance; it often has a greenish tint when new and can weather to a grayish silver. It requires sealing or staining every year or two to maintain its look and prevent cracking or warping. There are also considerations regarding the chemicals used, so it's not always recommended for surfaces where food is directly placed.
Cedar, a naturally durable softwood, contains oils and tannins that act as built-in preservatives against rot and insects. Its greatest appeal is its beauty: rich color, straight grain, and a lovely aroma. It weathers gracefully to a silvery-gray if left untreated. While more expensive upfront, it requires less maintenance; a clear sealant every few years is often sufficient. However, it is generally less dense and can be softer than pressure-treated pine, making it slightly more prone to dents and scratches.
So, which is better? For maximum durability and lowest cost, especially for ground-contact or high-moisture areas, pressure-treated wood is a robust choice. For superior natural beauty, lower maintenance, and a chemical-free option where the bench will be a focal point, cedar is worth the investment. Your final decision should balance your budget, desired maintenance level, and the visual impact you want for your outdoor space.
