No, we do not. All wooden parts of our products are made exclusively from solid oak. Each piece of furniture is made from natural solid hardwood and just as the trees in our forests are not identical, each individual piece of furniture has its own unique markings. It is not uncommon to find several grain variations in the same piece of furniture. Grain variations in solid wood furniture can include the use of sapwood and heartwood, pitch pockets, and mineral deposits. These natural markings have absolutely no effect on the furniture’s durability or structural integrity. Cheaper furniture that is mass-produced is often made of low-quality wood or plastic veneers that have undergone a multi-step chemical process of bleaching, texturizing and staining in order to mask these natural characteristics of wood. At Oak Concept Furniture, we prefer the real thing. Knots and other characteristics are much like the nubs you find in such fine fabrics as silk and linen, true indications of genuine quality.
