A wobbly, loose, or broken sofa leg is a more common issue than many people realize and can quickly undermine both the comfort and safety of your favorite piece of furniture. Fortunately, with a little patience and the right knowledge, most sofa leg repairs can be handled confidently at home, usually without calling a professional or buying a replacement sofa. In this article, we’ll walk you through how to fix sofa leg problems, from a simple tightening job to tackling more complex structural repairs. Even if it’s your first DIY furniture project, you’ll find that restoring your sofa’s stability is an achievable and satisfying task.

First, Diagnose the Problem: What’s Really Broken?

Inspect Your Sofa Before Getting Started

Before grabbing your tools, take a moment to carefully identify the problem. Start by tilting the sofa onto its back or side—be sure to use a helper to avoid injury or accidental damage. Examine the leg in question and its attachment point to get a clearer picture of the issue. The first step is identifying the type of leg your sofa has.

Determine the Type of Sofa Leg

Many sofas use screw-in legs with a single hanger bolt that twists into a metal T-nut or threaded insert in the frame. Others may feature bolt-on legs, secured by several screws or bolts, or legs that are integrated into the frame with dowels or metal brackets. Once you’ve identified the leg style, assess the damage. If the leg wobbles but remains undamaged, the problem might be a loose thread or screw.

Assess the Damage Thoroughly

Look closely at the mounting area. The wooden section around the mounting point could be chipped, the mounting plate or T-nut might be loose or broken, or in some cases, the sofa’s wooden frame may be split or cracked. For sofas with screw-in legs, stripped threads or a failed threaded insert are common causes of instability. Gently wiggle the leg to check for movement or stripped threads. If you notice these issues, repairing or replacing internal hardware may be necessary to restore stability.

Gathering Your Tools and Repair Materials

Proper preparation ensures that your repair process will proceed smoothly and safely. Begin by gathering the essential hand tools—these usually include a set of screwdrivers, an adjustable wrench, pliers, a power drill with suitable bits, and a rubber mallet. These tools are often sufficient for most basic repairs.

Adhesives and Fillers

Depending on the type of repair needed, you may also require adhesives or fillers. High-quality wood glue is ideal for repairing splits or loose joints, while two-part epoxy is particularly effective for filling gaps and reinforcing damaged areas. For cosmetic touch-ups or small repairs, wood filler can be a useful addition to your toolkit.

Replacement Hardware and Reinforcements

Often, replacement hardware is necessary to complete a thorough repair. Stock up on items such as T-nuts, hanger bolts, and wood screws of various lengths. For reinforcing weakened frames or joints, consider having corner braces or mending plates readily available. By assembling these materials in advance, you’ll be well-prepared to address any issues as they arise.

The Quick Fix: Tightening a Loose Screw-In Leg

Restoring a Loose Sofa Leg

Sometimes, fixing a loose sofa leg is a straightforward process of reestablishing a secure connection. Start by turning the leg clockwise by hand until it fits snugly against the frame. Hand tightening is often sufficient to eliminate minor wobbles and restore stability.

Using Tools for a Secure Fix

If the leg remains loose after hand tightening, use pliers to apply a bit more torque. Grip the exposed metal hanger bolt with the pliers (be sure to avoid clamping the wood to prevent damage) and turn gently. A slight additional turn—about a quarter—should help secure the leg. However, exercise caution to avoid overtightening, which could strip the threads.

Inspecting and Securing Hardware

Examine the T-nut or mounting plate inside the sofa frame, as this hardware provides the structural foundation for the leg. If the hardware is loose, use a screwdriver to tighten the screws holding it in place. A secure mounting plate or T-nut ensures the leg remains firmly attached. If you find the hardware spinning freely or damaged, replacing or re-seating it will be necessary to ensure a durable repair.

How to Fix Sofa Leg: with Stripped Threads or Frame Damage

In many cases, a more involved process is necessary, especially if the T-nut is stripped or the frame has suffered damage.

Step 1: Remove the Old Hardware

Start by fully unscrewing and removing the leg. Examine both the leg and the mounting hardware. Use pliers or a flathead screwdriver to carefully pry out the damaged T-nut or threaded insert from the frame. Avoid splintering the surrounding wood if possible.

Step 2: Repair the Wooden Frame (If Needed)

If the hole where the leg attaches has become enlarged or splintered, you’ll want to address that next. For minor cracks or splits, apply a liberal amount of wood glue to the damaged wood fibers, then clamp the area firmly until the adhesive has fully dried. For larger voids or severely damaged holes, mix and knead a two-part epoxy putty. Fill the void and allow it to cure according to the manufacturer’s instructions, creating a new, strong base for your hardware.

Step 3: Drill a New, Clean Hole

Once the repair is solid and fully cured, use a drill with the appropriate bit size to create a clean, precise hole for the new T-nut or threaded insert. The hole should match the diameter of the insert barrel as closely as possible for a snug fit.

Step 4: Install the New T-Nut

With the new hole ready, insert the T-nut into the top side of the frame where the leg attaches. Tap it into place using a hammer and gentle, controlled force, seating the prongs firmly into the wood. Make sure the T-nut is completely flush with the frame so the sofa leg mounts evenly.

Step 5: Re-Attach the Leg and Test

Screw the sofa leg back into the fresh T-nut or insert, turning it until it’s seated snugly and aligned with the rest of the legs. Carefully set the sofa upright and press gently on each corner to test stability. The repaired leg should now be firm and secure.

Reinforcing a Weak Corner or Cracked Frame

Assessing the Damage

If the attachment point has been repaired but the area still feels weak, additional structural support may be necessary. Begin by inspecting the corner or frame for small splits or cracks. Inject wood glue deep into any visible crevices, ensuring the glue penetrates fully. Once applied, clamp the area tightly and allow it to cure according to the glue’s instructions. This simple step can help restore much of the frame’s original integrity.

Adding Reinforcement

To ensure long-term stability, especially if the area has been stressed repeatedly, consider adding a metal corner bracket or mending plate. Position the reinforcement across the inside corner where the leg connects to the frame, and securely fasten it with screws, following the manufacturer’s guidelines. This added support helps distribute stress evenly and strengthens the repaired wood.

Rebuilding Severely Damaged Areas

For severe cases where the original wood is too damaged to be saved, construct a new mounting block. Cut a solid piece of wood to fit snugly within the damaged section of the sofa frame. Attach the block using a combination of wood glue and screws to create a durable hold. Once securely in place, reattach the sofa leg to the new mounting block as you would with the original frame. This method provides maximum strength and ensures a stable repair.

Repairing a Broken Wooden Leg

Using Wood Glue for a Clean Break

When the wooden leg itself—not just the hardware or frame—has broken cleanly, wood glue and a strong clamp might be all that’s required. Start by spreading a generous amount of wood glue across both broken surfaces. Carefully align the pieces to ensure a precise fit, and use a clamp to hold the joint tightly in place for at least 24 hours. Once the glue has fully cured, sand the repaired area to smooth out any excess glue or irregularities, and touch up the surface as needed to restore its appearance.

Replacing a Damaged Wooden Leg

For a leg that is splintered, shattered, or has a compromised hanger bolt, replacement is often the most reliable and durable solution. Bring an intact leg to a hardware store or furniture supplier to ensure the replacement matches the size, shape, and wood tone of the original. This careful selection will help maintain the sofa’s structural integrity and aesthetic appeal. Once you’ve secured the appropriate replacement leg, follow the manufacturer’s instructions to attach it securely to the frame.

Final Checks: Leveling and Floor Protection

With the repair complete, check that the sofa sits level on all four legs. Slight unevenness is common, especially on older sofas or after a significant repair. If needed, install screw-on levelers to the bottom of the legs or apply adhesive felt pads to compensate.

Be sure to add protective pads—felt or soft rubber—to the base of all legs. This step guards against scratches on hardwood or tile flooring and allows the sofa to slide more easily for cleaning or rearranging.

Troubleshooting Lingering Wobbles and Squeaks

Even after careful repairs, minor issues can persist. If you hear a squeak when you sit or move the sofa, it’s likely due to wood-on-wood contact. A small amount of paraffin wax, bar soap, or silicone lubricant applied at the connection point usually silences these noises.

Should you still feel a wobble after repairing the leg, double-check the other three legs. Sometimes a second problem remains undetected, or the floor itself is uneven. Swapping the positions of the legs or checking the floor with a level can help isolate the cause.

Conclusion

Successfully repairing a sofa leg is a rewarding accomplishment that saves money and extends the life of your furniture. By diagnosing the problem carefully, using the right supplies, and reinforcing the frame or leg as needed, you can restore comfort and security to your seating. Knowing how to fix sofa leg issues empowers you to tackle common household repairs confidently and brings the peace of mind that comes with well-maintained, lasting furniture.
