Most bean bags sold in Australia are filled with expanded polystyrene (EPS) beads — the small white balls that compress underweight, spring back over time, and occasionally escape across the floor. EPS works well for comfort and longevity, but it's a petroleum-derived plastic that doesn't biodegrade and is difficult to recycle.
If you're refilling an existing bean bag and want to avoid polystyrene, or you're filling a DIY cover and want a natural alternative, there are several genuinely good organic options available in Australia. This guide covers the ones worth considering — what they feel like, how they hold up, and where to find them.
For context on why some people move away from EPS, our posts on the environmental impact of polystyrene and whether EPS filling is eco-friendly cover the trade-offs in detail.
What to Expect from Organic Fillers
Before working through the options, it's worth being clear about a few realities that apply to most natural fillers compared to EPS:
- Weight: Most organic fillers are heavier than EPS, sometimes significantly. This affects how portable the bean bag is.
- Longevity: EPS is very durable. Natural fillers vary — some last well, others compress permanently or degrade faster.
- Volume: You'll often need more organic filling by weight to achieve the same feel as EPS.
- Cost: Quality natural fillers tend to cost more than standard EPS, though recycled and DIY options can be cheaper.
- Feel: The comfort profile is different. Some people prefer it; others find EPS still wins on responsiveness.
With that framing in place, here are the options worth taking seriously.
1. Biofoam Beads
Biofoam is the closest organic substitute to EPS in terms of look, feel, and behaviour. Made from natural biopolymers derived from plants, biofoam beads are lightweight, retain their shape well, and behave almost identically to polystyrene in a bean bag. Crucially, they are fully compostable and biodegradable — unlike EPS, which persists indefinitely in landfill.
Biofoam is CO2-neutral, non-toxic, and safe around children and pets. It's the organic option most likely to satisfy someone who wants the familiar bean bag feel without the environmental footprint of polystyrene.
The main supplier of biofoam filling for bean bags is The Big Beanbag Company, which sells biofoam in bulk refill bags and also makes bean bags from largely recycled materials including repurposed plastic bottles. Their products are plastic-free in packaging and fully vegan. Availability varies, but they ship to Australia and can be found online.
Best for: Anyone who wants the EPS experience with a genuinely lower environmental impact. Also good for DIY bean bag covers where you want a lightweight, easy-to-work-with fill.
2. Natural Latex
Natural latex is derived from rubber tree sap and is widely used in premium mattresses and pillows. As a bean bag filler, it typically comes shredded or in small chunks — the off-cuts and off-spec pieces from mattress manufacturing that would otherwise go to waste. This makes it both organic and a form of recycled material.
The feel of shredded natural latex is different from EPS — denser, with more resistance and less of the "sinking in" quality. Some people find it more supportive; others miss the lightness of polystyrene. It's non-toxic, hypoallergenic, naturally antimicrobial, and doesn't off-gas like some synthetic foams.
When sourcing natural latex filler, look for GOLS (Global Organic Latex Standard) certification, which confirms the latex is genuinely organic rather than blended with synthetic materials. Mattress companies with eco-friendly or zero-waste focuses are the best source — many sell off-cut latex specifically as stuffing material.
Best for: People who want a denser, more supportive fill and don't mind the extra weight. Also good for bean bag beds and loungers where sinkage isn't as desirable.
3. Buckwheat Hulls
Buckwheat hulls are the outer casings of buckwheat grain — a byproduct of food processing that would otherwise go to waste. They're widely used in meditation cushions, yoga props, and therapeutic pillows precisely because they conform to body shape, provide firm support, and allow air to circulate freely.
In a bean bag, buckwheat hulls create a different experience to EPS — firmer, less springy, and with a gentle rustling sound when you shift position. They're considerably heavier than polystyrene, which limits portability but adds stability. They're fully biodegradable, non-toxic, and naturally resistant to dust mites.
Buckwheat hull filling is available in Australia through health and wellness retailers, specialty bedding stores, and online via sites including Amazon Australia and various natural living retailers. Buy food-grade or pillow-grade buckwheat hulls rather than agricultural grade.
Best for: Floor cushions, meditation seats, and bean bags used in a fixed position. Less suitable for bean bags that need to be carried or moved regularly.
4. Cedar Shavings
Cedar shavings are one of the more unusual but genuinely practical organic fillers. Cedar is naturally decay-resistant, which means the filling can last for decades without breaking down. It's also naturally water-repellent, making it one of the few organic options with any moisture resistance, and the cedar scent naturally repels moths and insects — useful for a bean bag in a garage, outdoor room, or storage area.
Cedar shavings are firmer than EPS and have a different texture under weight, but they compress predictably and hold their shape reasonably well. The natural fragrance is pleasant initially but fades over time.
Sources in Australia include pet supply retailers (cedar shavings are widely used as animal bedding), landscaping businesses that sell or give away off-cuts, and timber merchants. Buying from a local business that would otherwise discard the material is genuinely zero-waste.
Best for: Outdoor or semi-outdoor bean bags, utility spaces, and anyone who wants maximum longevity from an organic filler. Not ideal for bedroom use if strong scents are a concern.
5. Dried Beans, Rice, and Seeds
Bean bags were originally filled with actual dried beans — it's where the name comes from. Dried legumes, rice, lentils, and similar seeds can still be used as filling, and they're fully natural, biodegradable, and easy to source in bulk.
The practical drawbacks are significant enough that this option suits specific use cases rather than everyday bean bags. Dried beans are heavy, they can absorb moisture and become mouldy if the bag isn't kept dry, and they compress over time rather than springing back like EPS. They also need to be kept away from pets and vermin who may be attracted to the scent.
That said, for a small floor cushion, a door stop, a weighted lap cushion, or a bean bag heating pad, dried beans or rice are entirely appropriate and genuinely organic.
Best for: Small cushions, weighted items, bean bag heat packs, and short-term or utility uses rather than primary seating.
6. Recycled Textile Off-Cuts and Foam Scraps
Not strictly "organic" in the botanical sense, but worth including for the sustainability angle: shredded fabric off-cuts and foam scraps from furniture manufacturing are sometimes available as filling material. They're soft, non-toxic, and divert waste from landfill.
The feel is closer to a stuffed toy than a traditional bean bag — more like a giant plush pillow than the responsive, moulding quality of EPS. Some people love it; others find it too static in shape. This filling type is also available as a DIY option — old clothing, worn towels, and soft textiles can all be cut into small pieces and packed into a bean bag cover.
For more on this and other non-standard filling approaches, our post on alternative bean bag fillers covers the full range including recycled options.
Best for: DIY bean bags, children's bean bags where softness is the priority, and anyone committed to a zero-waste approach.

Is Recycled EPS a Middle Ground?
If you want lower environmental impact without giving up the familiar bean bag feel, recycled EPS is worth considering. Recycled polystyrene beads are made from post-consumer EPS waste — they perform identically to virgin beads but reduce demand for new plastic production. They're not biodegradable, but they do keep existing plastic out of landfill.
Our post on recycled bean bag filling covers whether it's actually a meaningful improvement over virgin EPS, and our eco-friendly filling guide compares the environmental trade-offs across filler types honestly.
Where to Buy Organic Bean Bag Filler in Australia
Availability varies significantly by filler type:
- Biofoam: The Big Beanbag Company ships to Australia. Also search for "plant-based EPS alternative" or "compostable packing peanuts" — some packing material suppliers stock similar products.
- Natural latex shreds: Search for eco-mattress companies in Australia that sell off-cut or recycled latex stuffing. Brands with GOLS-certified products are the most reliable.
- Buckwheat hulls: Available from natural health retailers, some health food stores, and online via Amazon Australia. Search for "buckwheat hull filling" or "buckwheat pillow stuffing."
- Cedar shavings: Bunnings, pet supply stores (sold as animal bedding), and local landscaping businesses.
- Dried beans in bulk: Bulk food retailers and wholesale grocers in most Australian cities.
