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.

It is the classic and most popular type of innersprings made of a 5-turn (convolutions) steel coil interconnected in rows by helical wire. Bonnell innersprings are reliable, durable and have very good resilience. The coils are manufactured from oven-tempered steel wire (to 300oC), phosphate coated and have a tensile strength of 1600-1800 N/mm2.
