About Our Barnwood Furniture: Barnwood is a unique natural resource and no piece has the exact same wood grain or color characteristics. On chair seats, all nail and knot holes are filled for a smoother user experience. On table tops and benches, you will need to request holes to be filled, if desired. Our reclaimed barnwood furniture uses 100% solid oak that has been kiln dried to exterminate all bugs, insect eggs, and fungus. Wood is sourced from barns primarily in the Eastern US and may be 200–300 years old.
