Foam – an environmentally friendly material with high elasticity, durability, and hypoallergenic properties. It adds firmness and comfort. It offers less bounce and creates a firmer surface, ideal for those who prefer that.

Non-elastic band– ideal for maintaining shape, with no stretch. Adds firmness and helps preserve furniture shape over time. Often used in frames of seats, backs, and armrests.

Zig-zag springs — used in the base of soft elements, usually seating. Made of durable galvanized steel bent in soft waves under high temperature. Springs are mounted crosswise to the frame using hinged plates or metal staples. Their wavy shape resembles a snake, hence the name.
