Pocketed coil systems are groups of independently wrapped coils in fabric casings. These coils can be joined together with either glue or sewn by thread. There is a broad range of durability in coils of this type. Longevity is determined by coil gauge, tempering and quality of steel.
A pocketed coil system conforms better to your body than mattresses using other coil styles. Linked coils like wire-tied coils require more padding to equal the conformity of encased units.
Pocketed coils are terrific for pressure point relief. Side sleepers love this type of mattress. These coils are best known for producing mattresses that reduce motion transfer side to side. Which can help minimize disturbing partners with tossing and turning during sleep.
A shortcoming is that for someone of above average weight may not get the comfort life they need. In addition, where the body is heaviest depressions can occur, if maintenance is not consistent. Remember to always rotate and flip your mattress regularly.
A two-sided mattress with a pocketed coil unit is best with not much additional padding. Since the springs do most of the contouring, you don't need to hide the feel of its coils. Flipping and rotating the mattress, will maximize the life of this support system.
