Mattress pocket spring is a type of spring system commonly used in mattresses to provide individualized support and comfort. Each spring in a pocket spring mattress is encased in its own fabric pocket, allowing it to move independently from the others.

This design offers several advantages. Firstly, it helps to minimize motion transfer, meaning that when one person moves on the mattress, the disturbance felt by the other person is significantly reduced.

Secondly, pocket springs adapt to the shape and weight of the body, providing targeted support at different pressure points. This maintains proper spinal alignment and eases discomfort in the back area.

The number and density of pocket springs in a mattress can also vary, influencing the level of support and firmness. Mattresses with a higher number of pocket springs tend to offer a more precise and luxurious sleeping experience.
