pocket spring mattress

Bag-contained springs are widely used in various sofa cushions and mattresses.
The products use quality carbon spring steel wires and non-woven fabrics. The steel wires are heat treated, which guarantees the high elasticity and good rigidness. The unique design of the bags is able to avoid abrasion and enhance the breathability of the spring cushions, resulting in sustained best state and recoil of the springs.
