The anatomical mattress of the Chic Strom company is of medium hardness and has independent closed-type springs (Pocket Springs) which are not connected to each other and are located inside fabric cases, forming rows. Thus they offer a soft and smooth feeling, following the movements of the body. As the main material, it contains polyurethane foam, which makes it cooler in high temperatures and at the same time provides a sense of immersion, but without isolating every movement of the body.
