The best filling: EPS beads explained
The straightforward answer to what's the best filling for a bean bag is EPS beads. But what exactly are EPS beads? They're small, foam pellets made from polystyrene, often called styrofoam beads.

They're incredibly lightweight, odorless, and hygienic—they don't absorb moisture or promote mold. Thanks to their fine yet stable structure, they conform perfectly to your body shape and provide ergonomic support.
There are alternative bean bag fillings, like foam shreds or natural materials. However, these can be heavier, less conforming, and often don't last as long as high-quality EPS beads.
How much filling your bean bag needs

Many people wonder: How much filling does a bean bag need? And how many liters of bean bag filling are ideal? The amount you need depends heavily on your bean bag's size. A large adult bean bag obviously needs more filling than a small kids' version. As a rough guide, here's what to expect:
- A standard-size bean bag needs about 200 to 300 liters of filling.
- An XXL bean bag or giant lounger bean bag can need up to 400 or even 500 liters of filling.
Typical refill packs like our bean bag filling 'Der Nachfüller' are perfect for restoring your bean bag to its original shape.

Refilling and finding the right amount
Now for the practical part: How much filling do I need when refilling my bean bag? The best approach is to do it gradually. Add EPS beads a little at a time and sit in your bean bag between additions. You want to be able to sink in comfortably, but also find a stable seating position without bottoming out. A good bean bag is full enough to provide support, but not so packed that it can't conform to your body.
Buying: bean bag with filling or separately?
When you're shopping for a bean bag, you have a choice: do you buy a complete bean bag with filling, or purchase the filling separately? We give you the advantage that our bean bags arrive perfectly filled. You don't have to fill them yourself—just unpack and relax. Only after extended use might you need to refill. These refill packs come in various sizes, so you get exactly what you need. Your adult bean bag with filling becomes your cozy relaxation spot again.
