It is made of hybrid composite barrier panels, thus providing a separate protective element. Modular design that provides ballistic and impact resistance for the entire furniture without requiring additional components. The goal is to develop a protective furniture system. Accordingly, the invention combines kinetic impact energy and ballistic shock waves into a single system.
