We use only select Western Red Cedar as our feedstock of choice, since it is simply the finest outdoor building material available! It is light, the resin is poisonous to insects, and the Species features an extremely high thermal factor. Western Red Cedar has 80% of the tensile strength of Oak, and is pound-for-pound stronger than steel! Western Red Cedar is also an appearance-grade wood. When properly coated with Sikkens Cetol, or Tung Oil, the grains stand out, providing high aesthetic appeal, and and long-lasting durability - even under severe conditions. It is not uncommon for a properly finished Adirondack Chair to last 100 years, there are many in existence to prove it. Naturally, these furniture pieces often become family heirlooms, and are handed down generations after generation, becoming sought after prizes for collectors. Our bunk beds are also hand crafted and meet CPSC codes, so not only are they safe but are so durable you can pass them on to the next generation
