Key Specifications & Features

Material: 100% Solid Sapele Hardwood for superior density, rot resistance, and longevity.

Please Note (Natural Timber Character): Timber is a living, natural product. Each piece possesses its own unique characteristics, which may include natural colour variations, unique grain patterns, knots, or minor surface shakes. These features are a natural hallmark of real wood and do not affect the structural integrity or quality of the product. Timber can also react to atmospheric changes in humidity and temperature, so be sure to store the timber appropriately. See our storage guide for details.
