The hidden worry behind the sofa cushions
You move a cushion, and there it is — a patch of mould. Maybe you didn’t spot the spill. Maybe they were stored in a damp garage. However it happened, that musty smell and dark marking feel like a bigger problem than you expected.
But before you give up on them completely, here’s the good news: not all mould damage means it’s time to replace your sofa cushions.
Let’s gently walk through what’s possible — and what to check before deciding what to do next.
First, how bad is the mould?
Mould loves damp fabric — especially soft furnishings that have been sat on, spilt on, or packed away wet. Left untreated, it spreads inside the layers of foam and fabric. But how far has it really gone?
Here’s what to look for:
- Surface-only mould: Small spots or patches, often dark in colour, without smell or deep dampness.
- Deeper mould: Strong musty odour, dampness through the cushion, or signs on both sides.
If you’re not sure which it is, this is exactly where a trusted local cleaner can help. At Art of Clean, our upholstery team often checks this during in-home visits… offering guidance without pressure.
Can surface mould be cleaned?
Yes… well, sometimes… and often without needing to replace the cushion.
If the mould is only on the fabric cover, it may be treatable with professional upholstery cleaning. Our team uses safe, effective methods suited to both modern and delicate fabrics.
In some cases, you can clean removable cushion covers separately. This is where our partners at Farthings Cambridge come in. Their dry cleaning service is especially helpful for bespoke or lined covers that need expert handling.
Important note: Home attempts — especially with vinegar or bleach — can cause permanent damage to both fabric and internal fillings. These DIY tips often make the smell worse or push the mould deeper.

What if the mould has reached the filling?
At this point, it depends on how far it has spread and what the cushions are made from.
If the internal foam or feather filling is affected, it’s best to speak with a local upholsterer. In the Cambridge area, we often refer clients to:
- Waterbeach Upholstery (Adrian Reed)
- Mickey Upholstery, Mill Road
They can assess whether replacing the inside filling is possible, while we handle the cleaning and treatment of the outer fabric.
Can mould be prevented once it’s treated?
Yes, and we strongly recommend it.
Once the cushions are dry and clean again, a few simple steps can help stop future issues:
- Store cushions in dry, well-ventilated areas… not garages or lofts prone to damp
- Dry wet spots quickly… especially if drinks or pets are involved
- Apply a protective finish… we offer fabric protector treatments that help repel moisture and reduce the risk of mould taking hold again.
