How do I refill my Original Slim Teddy beanbag? – Fatboy

You can do that with the refill, which you order here. Refilling is best done by two people:

Open the Velcro of your Original Slim Teddy. Also unzip the innerbag a bit.
Cut a corner of the refill packaging.
Put the refill with the cut corner in the Original Slim Teddy and make sure the refill is also in the inner pocket. Keep the bag of the refill and the opening of the Original Slim Teddy connected to each other.
The other person pours in as much refill as you think needed.
Close zipper and the cover of your Original Slim Teddy.
If you have any refill left over, you can keep it.
