Major Cost Factors Construction Frame may be molded plastic or wood. Soft woods are more likely to warp or split. Pieces should be joined with dowels or mortise and tenon joints rather than simply butted together. Exposed wood should be smooth and well finished. Look for corner blocks that are screwed and glued to secure corner joints.
Staples are a sign of lesser quality if used in place of screws.
The number of coil springs and how they are tied and reinforced will determine cost and quality. In better furniture many coils are used in close formation while in inferior pieces the coils are farther apart. Webbing is found under the springs. The webbing should be woven or laced tightly. In poor quality construction you can see between the webbing strips.
