Add corner braces or metal brackets

Screw L-shaped metal corner braces into the inside corners where legs meet the seat, tabletop, or apron. The braces reinforce the joint from the inside and resist the racking forces that cause wobble.

Why It Works

Corner braces create a rigid triangular connection between the leg and the frame. Even if the original wood joint is weakened, the metal bracket prevents the joint from flexing under load.

Tips

• Install on the inside where they won't be visible
• Use braces on all four corners, not just the loose one — reinforcing all joints prevents future wobble
• Drill pilot holes to prevent splitting, especially in hardwood
• Available at any hardware store for $1-3 per brace
