Definition of Insulator
Meaning of the Term as it Pertains to Mattresses
What is an Insulator?
An insulator is any material that acts as a barrier between a mattress's coil system and comfort layers. Also called the insulator pad, mattress insulation prevents comfort layers from contacting coils. Without an insulator, comfort layers could get tangled in coils or coils could poke through cushioning. Most mattress insulation is made from fiber or mesh.
