Kiln-dried lumber is less likely to absorb moisture that could cause the frame to swell, shrink or change shape. A good wood frame is joined together with dowels and reinforced with wood blocks that are glued and screwed to the framing members. Joints and panels that are stapled or nailed in place indicate poor quality. Some parts of the frame, particularly the legs, may be carved. Some manufacturers resort to molded wood compositions to imitate real carving.
Faux carvings are easy to recognize because they have a textured surface without any wood grain.
These applique carvings are not part of the wood and are glued in place. Over time, the glue can loosen and the carving will separate from the frame. After the frame is finished, the upholstery is added. Bands of webbing, made of tough woven fabric about four inches wide, are stretched across the bottom of the frame and tacked in place. Quality seat construction uses coil springs tied onto the webbing with strong twine.
