Small springs that work independently from each other that conform and adjust to body contours helping to eliminate roll together. Spring counts typically range from 1000 up to 30,000 and come available in soft, medium or firm tensions. Some mattresses can also be supplied with different tensions of spring within the same mattress to accommodate couples who require different feels. Pocket Springs are often more expensive and used mainly in higher quality products. Better quality pocket springs are encased in calico pockets, hand nested in a honeycomb pattern and centre tied with linen cord.
Interior sprung mattresses use a wide variety of fillings to create different properties and comfort options, as well as affecting price. Fillings are chosen for their resilience, durability and flexibility to absorb body moisture. In cheaper mattresses, fillings usually come in compact pads, in better quality models, layers of loose fillings in greater volumes are often used.
