The pillow filling (so-called hollow fiber) is a siliconized anti-allergic fiber of the highest quality, which will ensure a peaceful and healthy sleep. The spherical structure and silicone treatment cause fluffiness, softness, airiness, formability and volume stability. These properties guarantee that the pillow will be fluffy for a long time. This filling is produced by a technology that also allows washing while maintaining its shape and properties. The hollow fiber ensures a stable shape, full volume and prevents the multiplication of mites and other bacteria. You can additionally regulate the volume of the pillow by adding another filling, or by removing it as needed. 250 g will suffice to fill a small 35 x 45 cm pillow. To fill a large sleeping pillow 90 x 70 cm, 1000 g of filling is enough.
