Outdoor furniture is meant to be relaxing… until the cushions start going flat, sagging, or feeling like a pancake. If your outdoor lounge no longer feels as supportive as it used to, you’re definitely not alone. Thanks to Australia’s harsh climate — especially here in WA — outdoor cushions take a beating faster than most people realise.
Here’s why it happens… and exactly what you can do to bring your outdoor furniture back to life.
1. Sun Damage (UV Exposure) Weakens the Foam
Perth and WA sunlight is no joke. UV rays don’t just fade fabric — they break down foam from the inside out.
What happens:
- Foam cells weaken and collapse
- Cushion thickness gradually decreases
- Foam becomes crumbly or uneven
How to fix it:
Choose high-quality foam rated for outdoor use, such as reticulated quick-dry foam — designed to handle sun, heat, and moisture much better than standard foams.
2. Moisture, Rain & Dew Compress the Foam
Outdoor cushions absorb more water and humidity than most people expect — especially near the coast where salt air is constantly present.
Signs moisture is ruining your foam:
- Cushions feel heavy
- They take ages to dry
- They smell musty or damp
- They stay “compressed” after sitting on them
Moisture plus heat is the fastest way to destroy standard foam.
The solution:
Upgrade to reticulated foam or open-cell outdoor foam that drains water quickly instead of trapping it.
3. Low-Density Foam Loses Its Shape Faster
Many store-bought outdoor lounges use cheap, low-density foam to keep manufacturing costs down. Unfortunately, low-density foam compresses and flattens very quickly — especially with daily use.
What to look for instead:
- Medium-high density outdoor foam
- Foams designed specifically for frequent seating
- Australian-made foam (higher standards, better durability)
If your cushions are a few years old, upgrading the foam inserts will instantly improve comfort.
4. Heavy Use (Kids, Guests, Pets)
Outdoor areas are high-traffic zones. From weekend BBQs to family gatherings, cushions get far more use outdoors than indoors.
If you notice:
- Permanent dents
- Flattened “sit spots”
- Cushions that don’t bounce back
…it’s a classic sign the foam has reached end-of-life.
Fix:
Order replacement custom-cut foam inserts in the same size and thickness — your covers can stay exactly the same.
5. Incorrect Storage Over Winter
If cushions were stored while damp — or left unprotected during winter — the foam may have deteriorated.
Prevent this next time:
- Dry cushions completely before storing
- Use breathable storage bags, not plastic
- Avoid stacking heavy items on top of them
How to Fix Flat Outdoor Cushions
Here are the best options, depending on the condition of your existing cushions:
✔ Replace the Foam Inserts Only
Keep your current covers and simply order new foam inserts in the exact sizes you need.
Perfect when covers are still in good condition.
✔ Upgrade to Reticulated Quick-Dry Foam
The number one choice for outdoor lounges in WA.
- Drains water
- Resists mould
- Maintains shape
- Handles UV exposure
✔ Add a Dacron Wrap for a Plush, Full Look
Dacron wrapping helps cushions look fuller and extends the life of the foam.
✔ Order Custom-Cut Shapes for a Perfect Fit
Great for corner lounges, daybeds, poolside seating, caravans, boats, and custom outdoor furniture.
Bring Your Outdoor Furniture Back to Life
Flat cushions don’t mean you need to buy a whole new lounge. With high-quality, Australian-made replacement foam, your outdoor setting can feel brand new — and last double or triple the lifespan of standard cushions.
