How to Fix Sagging Sofa Cushions at Home: A Practical Australian Guide
We’ve all felt it — that slow, sinking feeling when you sit on the couch, only to realise the cushions no longer offer the support they once did. Sagging sofa cushions not only make your furniture look worn out, but they can also cause back discomfort and ruin the overall style of your living space.
Luckily, you don’t need to replace the entire sofa or spend hundreds on professional repairs. Here’s how you can fix sagging sofa cushions at home using affordable methods, many of which work beautifully for Aussie households managing humidity, wear, and everyday use.
Why Do Sofa Cushions Sag?
Sagging happens because of:
Worn-out foam or stuffing inside the cushions
Weak or stretched-out support webbing or springs underneath the cushions
Heavy daily use that compresses materials over time
According to the Furniture Industry Research Association (FIRA), cushion lifespan can be extended by regular maintenance — but most people wait too long, making fixes harder.
Simple Steps to Fix Sagging Sofa Cushions
Refill the Cushion Inserts
Unzip the cushion covers and check the foam inside. If the foam feels soft or misshapen, replace it with high-density foam (available from most upholstery or craft stores). You can also wrap the foam in a layer of polyester batting to create extra plumpness.
Add Cushion Support Boards
Place under-cushion support boards or a piece of plywood beneath the cushions. This helps reinforce sagging springs or webbing underneath. Many online stores in Australia now sell pre-sized sofa support panels for quick fixes.
Rotate and Flip Cushions Regularly
If your cushions are reversible, flip and rotate them to distribute wear evenly. This won’t reverse sagging but can slow it down significantly.
Check the Sofa Frame and Springs
If the sagging seems extreme, the problem might be under the cushions. Check if the springs or webbing are loose or broken and reinforce them with replacement straps or new springs (you may need a handyman for this part).
The Ultimate Solution: Add a Stylish Sofa Cover
Even after fixing sagging cushions, your sofa might still look tired or mismatched with the rest of your decor. That’s where a high-quality slipcover can work wonders. Not only does it refresh your sofa’s appearance, but it also holds cushions firmly in place, giving a tighter, more supportive feel.
