This particular topper was made of natural buckwheat shell. We use it to improve the properties of the already possessed mattress.
Buckwheat shells arrangement in the quilted pouches guarantees airness and controls the body moisture. When you move during the night mattress, shells gently massage your skin and subcutaneous tissue. Thanks to the buckwheat tannins, mites and bacteria have no access to not only your mattress, but also on the top of your skin.
