How to Choose the Right Foam Density for Your Cushions (Perth / WA Guide)

When it comes to replacing or upgrading your cushions, the quality of the foam you choose makes all the difference. In Perth and across WA, harsh weather conditions and heavy daily use can quickly wear out cheap foam. By understanding foam density and selecting the right option for your home, outdoor space, caravan, or boat, you’ll enjoy comfort that lasts for years.

What Does Foam Density Mean?

Foam density refers to the weight of the foam per cubic metre. It is not the same as firmness (soft vs firm), but it directly affects durability and comfort.

• Low Density Foam (18–23kg/m³)
  Budget-friendly but wears out faster. Often used for occasional seating or back cushions.

• Medium Density Foam (24–29kg/m³)
  A good balance of comfort and longevity. Perfect for lounge seating, outdoor cushions, and general use.

• High Density Foam (30kg/m³ and above)
  Premium durability. Ideal for everyday use, commercial seating, or high-traffic areas. Maintains shape and support for years.

Best Foam Densities for Different Cushion Types in WA

1. Lounge & Sofa Cushions

In Perth homes, medium to high-density foam works best. It provides comfort for everyday use while keeping cushions from sagging.

2. Outdoor & Patio Cushions

WA’s hot summers and coastal humidity can damage low-quality foam. Choose a medium-to-high density outdoor-grade foam that resists moisture and retains its shape.

3. Caravan & Camper Cushions

Travellers in WA need lightweight yet durable cushions. Medium-density foam balances comfort for sleeping and practicality for limited space.

4. Boat & Marine Cushions

For Mandurah, Fremantle, or Broome boat owners, high-density marine foam is essential. It withstands salt, sun, and frequent use without breaking down.

Why Foam Density Matters in Perth & WA

Western Australia’s climate—hot, dry summers and coastal environments—puts extra strain on foam products. By choosing the correct density, you:

• Extend the life of your cushions

• Improve comfort for family and guests

• Save money by reducing replacement frequency
