Introduction

A comfortable couch is the heart of a cozy living space. But over time, even the best sofas can start to sag, making them uncomfortable and unattractive. If your couch cushions have lost their shape and support, you don’t need to rush out and buy a new one. There are several simple and cost-effective ways to fix sagging couch cushions and bring them back to life.

In this guide, we’ll walk you through easy DIY fixes to restore your cushions and make your sofa feel as good as new.

Why Do Couch Cushions Sag?

Before jumping into the repair solutions, it’s essential to understand why couch cushions start to sag.

• Frequent Use: Sitting in the same spot repeatedly compresses the cushioning over time.
• Low-Quality Foam: Some sofas come with lower-density foam that flattens faster.
• Broken or Weak Support System: If the couch frame or springs are weak, the cushions won’t hold their shape.
• Natural Wear and Tear: Even high-quality furniture wears down after years of use.

Materials You May Need for Fixing Sagging Couch Cushions

• High-density foam replacement
• Polyester fiberfill stuffing
• Plywood or cardboard
• Upholstery needle and thread
• Batting for extra cushioning
• Scissors and measuring tape

Step-by-Step Solutions for Fixing Sagging Couch Cushions

1. Fluff and Rotate the Cushions

Before trying more advanced fixes, fluff and rotate your cushions regularly.

• Remove cushions and shake them to redistribute the filling.
• Flip and rotate them to ensure even wear.
• If your cushions have zippers, open them and manually adjust the filling inside.

2. Refill the Cushion with Polyester Fiberfill

If your cushions are filled with loose stuffing, they might just need a boost.

• Open the cushion cover and remove old stuffing if necessary.
• Add polyester fiberfill evenly to restore volume.
• Seal the cushion cover and fluff it up.

3. Replace Old Foam with High-Density Foam

Foam cushions naturally lose their resilience, but replacing them can make your couch feel brand new.

• Unzip the cushion cover and remove the old foam.
• Measure and cut new high-density foam to fit.
• Wrap the foam in batting for a smooth, plush feel.
• Insert the new foam and zip up the cover.

4. Use Plywood for Additional Support

If the sagging is caused by weak springs or a soft couch base, a plywood board can help.

• Remove the cushions and measure the couch frame.
• Cut a piece of plywood to fit inside.
• Place it under the cushions for firmer support.

5. Repair or Replace Broken Springs

Weak or broken springs can contribute to a sagging sofa.

• Check underneath the couch for loose or damaged springs.
• Use pliers to tighten any loose springs.
• If necessary, replace broken springs with new ones.

Preventing Future Cushion Sagging

• Fluff and rotate cushions regularly.
• Avoid sitting in the same spot repeatedly.
• Use a protective cover to reduce wear and tear.
• Reinforce support structures as needed.
