Pocket spring units are made of individual spring units (rather than the interconnected ones) wrapped in a small non-woven fabric sack pocketed and held in a row among one another, forming the unit. Due to the fact that they can move independently, the total flexibility allows the mattress to respond to the user's precise shape, weight and size. Pocketed spring units are particularly known for their high point by point elasticity, leading to independent motion, thus avoiding disturbing the other sleeper when one sleeper moves.
We manufacture pocketed innerspring units of barrel shape in a fully automatic line. The spring coils are placed into their individual non-woven fabric pockets and sealed on the side. The spring coils' wire diameter can be 1.35mm, 1.50mm, 1.80mm and 1.90mm and the height can range from 10cm to 15cm thus varying the firmness of the mattress. The latter is also modified according to the diameter of the coil which effectively affects the coil count per particular size as well as the tensile strength of the steel wire used that ranges from 1600-2000 N/mm2.
For transportation purposes in order to maximise the loading capacity inside a container, the innerspring units are roll packed.
