The dining set’s dark stain finish enhances its natural, rich dark wood look. Rest comfortably knowing the all-weather outdoor dining set is built from premium, hand-selected dark shorea hardwood. Dark shorea is an exceptionally sturdy natural wood that doesn’t require oiling except to maintain a desired color. Occasional oiling will help maintain the finish from the effects of rain, sun, and dew, or you may allow it to weather to a silver patina over time. As an added natural bonus, dark shorea is resistant to rot, mildew, and insects. This set’s wood is also FSC-COC certified, which guarantees it has been harvested from forests deemed to be under the practice of environmentally and economically sustainable forestry.
