A sagging outdoor sofa seat can ruin the comfort and aesthetics of your patio or garden furniture. Fortunately, there are several effective ways to restore its support and extend its lifespan. Here’s a step-by-step guide to fixing a drooping sofa seat:

1. Identify the Cause: Check if the sagging is due to weakened frame support, worn-out cushions, or broken springs.

2. Reinforce the Frame: If the frame is weak, add extra support by attaching wooden slats or metal brackets underneath the seat.

3. Replace Cushions: Over time, foam cushions lose their firmness. Replace them with high-density foam or outdoor-grade cushions for better durability.

4. Tighten or Replace Springs: If the sofa has springs, tighten loose ones or replace broken ones to restore bounce and support.

5. Use Support Straps: Install nylon or polyester support straps across the seat base to distribute weight evenly and prevent future sagging.

6. Regular Maintenance: Keep the sofa dry and clean to avoid moisture damage, which can weaken materials over time.

By following these steps, you can easily revive your outdoor sofa and enjoy comfortable seating for years to come. For severe damage, consult a professional upholsterer.
