🪶 How Much Crumbed Foam Do You Need for Your Bean Bag? (Australian Sizing Guide)

When it’s time to fill or refill your bean bag, one of the biggest questions is always: how much crumbed foam do I actually need?
Choosing the right amount ensures your bean bag is soft, supportive, and perfectly shaped — without feeling over- or under-stuffed.

Crumbed Foam Australia makes this process easy with high-quality, eco-friendly foam made right here in Australia. But before you order, here’s a quick guide to help you measure and calculate how much to buy.

🧮 Step 1: Measure Your Bean Bag Size

Start by measuring your bean bag’s width, height, and depth in centimetres. Multiply these three numbers together, then divide by 1,000 to get the litre capacity.

Example:
If your bean bag is 100 cm × 100 cm × 100 cm
→ 100 × 100 × 100 = 1,000,000 cm³
→ 1,000,000 ÷ 1000 = 1,000 L (litres)

🧱 Step 2: Convert Litres to Kilograms

At Crumbed Foam Australia, 1 kg of crumbed foam equals approximately 40 litres of volume.
Use this simple formula:

Litres ÷ 40 = Kilograms required

Example:
1,000 L ÷ 40 = 25 kg of crumbed foam

That means a 25 kg bag will perfectly fill a 1,000 L bean bag with soft, supportive comfort.

🪑 Step 3: Adjust for Your Preferred Firmness

Some people love a super-plush feel, others prefer firmer support.
Use this quick guide:

👉 Tip: start with slightly less foam, then top up as you test — crumbed foam expands beautifully when fluffed and settles over time.

🌦️ Step 4: Choose the Right Type — Indoor vs Outdoor Foam

🧼 Bonus Tip: Refill Regularly

Over time, foam settles slightly. To keep your bean bag feeling plush and full, add a small top-up every 12–18 months. It’s affordable, simple, and keeps your furniture looking new.
