The mattress is formed by making built-in spring element

The mattress is formed by making built-in spring element. It is a series of coil, through additional line connected to each other. Bias spring is also an hourglass shape, but the top and bottom is flat, so that the coil hinged between the action. Continuous built-in spring is a long wire bundle, unit configured to S form. Pocket coil wrapped in cloth, fabric and connect it to the adjacent coil housing units. Mattress can be a spiral spring 250 to 1000. In the mattress with fewer coil, use the heavier wire. Each coil shall be connected in a variety of ways. A common approach is to use spiral, spiral line extends along the top and bottom of the spring, the coil system together. Sometimes rigid border around the periphery connection to stabilize the built-in spring unit. In most cases, the mattress processing companies said don't make the built-in spring element. Conversely, the built-in spring element of production to manufacture the spring outside companies. As soon as we receive the complete built-in spring unit, mattress factory work begins. Maker applied buffer layer, in order to handle and comfort products. Textile adornment layer fixed manually, spring. There are basically two adornment layer insulation and buffer layer. Insulator directly fixed, spring, and to reduce the next layer ( Buffer layer) Molded into the coil. Although the use of an insulator is a standard, but there were significant differences in the number of buffer layer on the quantity. The buffer layer thickness in the range of 2 to 8 layer, thickness of 14 inches to 2 inches ( 。 63-5 cm) 。 The buffer layer determines the product of feel and comfort. Thickness for 63-5 cm) 。 The buffer layer determines the product of feel and comfort. Thickness for 63-5 cm) 。 The buffer layer determines the product of feel and comfort.
