Stabilizing an outdoor table on sweetgum balls can be tricky due to their irregular shape and tendency to roll. Here are the best methods to ensure your table stays level and secure:

1. Use Adjustable Table Legs: If your table has adjustable legs, extend or retract them to compensate for the uneven surface created by the sweetgum balls. This is the simplest solution for minor imbalances.

2. Place a Stable Base: Lay a flat, sturdy board or patio stone under the table legs to distribute the weight evenly and prevent sinking or wobbling.

3. DIY Shims: Cut small wooden shims to wedge under the table legs where needed. This is a cost-effective way to fine-tune the balance.

4. Rubber Caps or Mats: Attach rubber caps to the table legs or place non-slip mats underneath to grip the sweetgum balls and reduce movement.

5. Ground Preparation: Clear the area of sweetgum balls before setting up the table, or rake them aside to create a flatter surface.

For long-term stability, consider relocating your table to a smoother area or using a permanent leveling solution like concrete pavers. With these tips, you can enjoy a steady outdoor table even on challenging terrain.
