Thinking about replacing your sofa? Before you do, it’s worth checking what’s inside, because in most cases, a tired lounge can be brought back to life with a few simple DIY fixes.
If your sofa feels uncomfortable or saggy, the issue is almost always one of three things: webbing, springs or foam. All of these can be replaced without buying a new lounge, and we supply everything you need to do the job yourself.
Here are 3 common signs your foam specifically needs replacing 👇
1️⃣ Your cushions sink as soon as you sit down
Foam that no longer rebounds has lost its firmness and support.
2️⃣ You can feel the frame, webbing or springs through the cushion
This means the foam layer has compressed too much to act as a comfort barrier.
3️⃣ The foam feels lumpy, uneven or has started breaking down
Old foam can degrade internally, causing discomfort and misshaping.
If any of these sound familiar, replacing just the foam can completely refresh your sofa’s comfort and support - without the cost of a new lounge.
