Hardwood tables are designed with durability and longevity in mind. The hardwood tables are knot-free to ensure a clean, uniform look that is also stable and durable. Knots, which are imperfections in the wood, are removed during the manufacturing process to prevent warping and cracking and create a beautiful and durable table. Hardwood tables should also have a non-toxic finish free of any harmful chemicals. To keep your home healthy, make sure to check for a non-toxic finish before purchasing a solid wood table for your dining room.
