Hi-Low Detail


Hi-Low® offers the ability to create a variety of mattress layouts. That's because the variable-height coil system features cavity-filled zoning, giving you space for smaller coils, foams, or gels.

  • Create a traditional zoning layout with greater support at the hips and shoulders.
  • Boost coil count by adding micro-coil top layers.
  • Offer exceptional comfort through distinct firmness differences.
