What is an Offset Coil?

An offset coil system is a configuration found inside an innerspring mattress that is constructed of hourglass-shaped coils with flat sides on the top and bottom of the each spring. This flat design allows for better hinging when the coils are positioned together, and it helps adapt to the shape of different sleepers' bodies. This stability gives sleepers firm support when they lie down.

Benefits of an Offset Coil System

  • An offset coil system provides a firm surface for sleepers when they lie down.
  • This configuration adjusts to people's body types, creating optimal comfort.
