Felt is very thick non-woven cloth which consists of pressed wool or synthetic materials. Depending on the purpose of its usage the following types of felt can be distinguished – thin wool, semi-coarse wool and coarse wool. Due to addition of a low melt fiber felt fibers are thermally bonded.

Felt provides different degrees of rigidity depending on the combination of layers as well as planking materials. Felt is often used in the production of furniture to cover spring blocks. Its stiffness and low deformation characteristic make felt an excellent lining material to be put under foam or the fibers for mattresses.

Felt cloth does not contain any glue or other chemical substances at all which makes it an environmentally friendly product. Felt cloth is mainly produced in the form of rolls with different density. Rigidity of the material is regulated during the production process.
