Pocket Sprung Mattresses
Pocket springs are individually wrapped coil systems that are stitched into mattresses below a comfort layer of foam or other material. Unlike traditional bonnell spring systems that are interconnected, pocket springs are entirely independent allowing for added contour and pressure point relief than the more traditional bonnell spring models.
The general rule on pocket coil systems is the more coils, the more responsive and motion controlled the mattress is, while still providing support. This directly translates to more comfort.
In most pocket spring beds, there is a layer of memory foam or latex foam above the pocket spring array so that the sleeper gets both the benefits of contouring foam and the comfort of the pocket springs.
Pros: Durable materials and superior comfort to traditional bonnell spring systems.
Cons: Sleepers should be equally as interested in the foam that is wrapped around the coil system - if that is low quality, the bed still may be uncomfortable.
