Definition of Pocketed-Coil

Meaning of the Term as it Pertains to Mattresses

What is a Pocketed-Coil?

A unique independent coil design created and used exclusively by the Simmons mattress company, pocketed-coils are individually wrapped high-carbon springs that compress freely from one another to provide custom support. Coils react to specific pressure areas, and the heavier portions of the body, like the hips and shoulders, sink deeper into the mattress, which allows for proper spinal alignment. The free-moving coil design also offers excellent motion isolation.

The pocket coil concept is a hugely popular advancement in the mattress industry. Most mattress manufactures make their own versions of the individually wrapped pocket coil design. Other names used to represent the pocketed-coil concept include pocketed spring, encased spring, Marshall coil, and wrapped coil.
