Bean bag chairs are usually filled with expanded polystyrene (EPS) beads, though foam, EPP beads, and natural fills like buckwheat hulls are also common.
That lumpy, supportive feel you love comes down to one thing: what’s inside the bag. The fill decides the chair’s weight, comfort, and how often you’ll be topping it up. Most bean bags you’ll find today use EPS beads—the classic lightweight option—but the market has broadened considerably. Knowing what’s inside helps you pick a chair that holds its shape for years, and what to buy when it’s time to refill.
The Most Common Fill: EPS Beads
Expanded polystyrene beads are the standard. They’re the small, white, lightweight pellets that pour easily and conform to your body. They are cheap to produce, which keeps chair prices down, and they offer that signature “sink-in” feel.
Their main drawback is compressibility. Over time, the beads lose their loft and flatten out. You’ll notice the chair feeling less supportive, which is usually the signal to add more. If a bag splits or a child unzips it, loose beads are a choking and asphyxiation hazard, so keep an eye on the bag’s condition.
Foam, EPP Beads, and Natural Alternatives
Not every brand uses EPS. Major manufacturers have built entire product lines around shredded polyurethane foam. Lovesac explains that its foam-filled sacs use shredded foam rather than EPS, giving a firmer, more supportive seat that bounces back rather than flattening out. CordaRoy’s similarly stuffs its convertible furniture with polyfoam. Foam fills are heavier and more expensive, but they hold their shape considerably longer.
Other options you’ll see:
- EPP beads: Expanded polypropylene. They’re more resilient than EPS and hold their shape better, but they cost more.
- Buckwheat hulls and millet: Natural fills that are firm, breathable, and eco-friendly. They make for a denser, less “sinky” seat.
- Kapok, latex, and hemp fiber: Soft, plant-based fills, though they can compress and clump more noticeably than synthetic options.
Weigh the trade-offs carefully. If you want the classic feel and a low price, EPS is your fill. If you want a chair that stands up to years of daily sitting, foam is worth the premium. If material sourcing matters to you, natural fills deliver—just know they’ll need more fluffing to keep their shape.
Do Bean Bags Need Refilling?
Yes, and it’s a normal part of ownership. The fill compresses with daily use, and a manufacturer guide on refilling notes that topping up every 1–2 years restores comfort and shape. That’s not a defect; it’s the nature of loose fill.
When you refill, aim for about 75–80% capacity. Overfilling is the most common mistake—a packed-tight bag becomes stiff and uncomfortable instead of cozy. For the refill job itself:
- Work in a contained space to catch stray beads.
- Use a wide funnel or a cut plastic bottle to pour without a mess.
- Pour slowly to avoid static cling and spillage.
If a bag has a refillable zipper, ensure it locks shut. Safety guidance recommends a zipper lock that needs a special tool, so a child can’t open it and access the loose fill. Non-refillable models should have the zipper disabled or removed entirely.

FAQs
How much does it cost to refill a bean bag?
Refill costs vary by fill type and bag size. A large bag of EPS beads typically runs $30–$60, while foam refills can cost $50–$100 or more for a big sac. The exact amount you need depends on the chair’s capacity and how flat it has become.
Are the beads in bean bags toxic?
EPS beads and most synthetic fills are considered non-toxic and are widely used in packaging and furniture. The bigger risk is physical: loose beads are a choking hazard for small children if the bag splits. Keep damaged chairs away from toddlers.
How do I know if my bean bag needs more filling?
If you sink to the floor and the chair feels like a flat pancake, it needs a top-up. A properly filled bean bag should let you sit “in” it slightly while still supporting your hips above the ground. If the fabric bunches under you, add more fill.
