Which joints are commonly used to assemble wooden furniture?

In the furniture industry, the primary goal of a joint is to connect wooden members with maximum mechanical strength while remaining as unobtrusive as possible. Because natural wood is subject to movement caused by changes in moisture content, cabinetmakers have long relied on traditional designs to ensure structural integrity.12

Commonly used joints include:

• Dovetail joint: Frequently used for joining two flat members at right angles, such as the sides of a drawer. It features a flaring tenon that fits into a mortise, creating an interlocking connection that resists pulling apart.13
• Mortise and tenon: A classic method used to join a horizontal member to a vertical member within a frame.14
• Dowelled joint: Employs dowelling to provide additional mechanical strength to the connection.1

Most of these joints rely on a combination of precise mechanical fit and glue to maintain their stability over time. While modern manufacturing often utilizes inert man-made materials like plywood to mitigate wood movement, these traditional joinery techniques remain essential for high-quality furniture construction.12
