Additional filling for adjustable Familon pillows to provide individual sleeping comfort. If there is not enough filling in the adjustable pillow with a zipper, you can order fibre filling in 100g refill bags. With the aid of the additional filling, you can adjust the height and firmness of the pillow to suit your needs. Adjustable Familon pillows include the Shaped Body pillow, Refill pillow, Refill giant pillow, and Custom pillow. The additional filling is made of soft and individually mouldable ball fibre. The mouldable and repeatedly washable filling fibre is also ideal for crafts.
