Outdoor sofa cushions are prone to sagging due to exposure to weather, frequent use, and poor support. To keep them firm and comfortable, follow these expert-approved tips:

1. Choose High-Quality Materials: Opt for weather-resistant, high-density foam or quick-dry polyester fiberfill cushions. These materials resist moisture and retain shape longer.

2. Use Supportive Cushion Covers: Reinforced covers with sturdy zippers and UV-resistant fabric prevent stretching and sagging.

3. Rotate and Flip Cushions Regularly: Even out wear by rotating and flipping cushions every few weeks to distribute pressure evenly.

4. Add Cushion Inserts or Straps: Insert plywood or mesh support beneath cushions, or use non-slip straps to keep them in place.

5. Store Cushions Properly: When not in use, store cushions in a dry, shaded area or use waterproof storage bags to prevent moisture damage.

6. Clean and Dry Thoroughly: Regularly clean cushions with mild soap and allow them to dry completely to avoid mold and material breakdown.

By implementing these strategies, your outdoor sofa cushions will stay supportive and comfortable for years. Invest in quality and maintenance to enjoy a sag-free outdoor lounging experience!
