Walnut Wood Furniture are available in a wide variety of styles and finishes. From traditional dining sets with curvaceous lines and cabriole legs to modern dressers with straight lines and sharp angles, walnut is a versatile wood that suits almost any decor. The natural qualities found in this wood -- aesthetic appeal, strength, durability -- make walnut furniture an enduring favorite. It's prized by woodworkers for its strength, grain and color. It polishes to a very smooth finish, and the color ranges from creamy white in the sapwood to a dark chocolate in the heartwood.
