The filler is the main component of any mattress in terms of volume. Fillers are located between the mattress cover and the spring block, or, in the case of a springless mattress, completely fill the product cover in several layers.
This part of the mattress can be used both as an insulating layer and to give the mattress a certain firmness.
Fillers in mattresses are divided into artificial and natural. Thanks to modern production technologies, the former are in no way inferior in terms of operational and quality characteristics to the latter.
