pocket coil spring

1.​‍​‌‍​‍‌​‍​‌‍​‍‌ Double wire feeding zones are applied in the process with different wire diameters for clearly differentiated support zones. 2, Durability is improved by overall heat treatment, as the product is able to pass 100,000 cycles without any visible deformation. 3, The sewing of the fabrics to each other is achieved by ultrasound welding of the edges, which removes the ability to be torn by wear and aging of the cotton ​‍​‌‍​‍‌​‍​‌‍​‍‌fabrics.

1、One​‍​‌‍​‍‌​‍​‌‍​‍‌ of the main features of the pocket coil is the small diameter of the wire and close spacing. By installation 400-600 springs per square meter, this method achieves a very dense distribution of support points. 2、A wire diameter of 0.9mm-1.6mm is chosen in order to make the spring softer and more responsive. Such a spring is able to follow body shape and therefore is suitable for comfort layer of a mattress. 3、In most cases, they are working together with the main support springs to form a double-layered composite ​‍​‌‍​‍‌​‍​‌‍​‍‌structure.
