Spring Air Reserve Royal Cushion Firm Mattress

A substantial, supportive feel with comfort that welcomes you into bed.

There is something reassuring about lying down on a mattress that feels comfortably cushioned and firmly supported. The Reserve Royal Cushion Firm brings those qualities together with responsive latex, a NanoCoil comfort layer, and a three-zone encased coil system.

It is a mattress worth taking your time with. Settle onto your back, turn onto your side, and notice how the surface responds as you move. The combination of cushioning and underlying support is what gives the Royal its character—and trying it yourself is the best way to understand the difference.

Why shoppers should try it

  • Responsive comfort: Latex and NanoCoils respond as you change position, giving the comfort layers a buoyant, adaptable feel.
  • Support with purpose: The three-zone Marshall encased coil system provides a structured foundation beneath the cushioning layers.
  • A more settled sleeping surface: Individually encased support coils respond separately, helping limit movement across the mattress.
  • Support around the perimeter: High-density foam encasement reinforces the edges, an important detail to feel when sitting down or sleeping closer to the side.

What’s inside

  • Extra Firm Latex: A resilient comfort layer that contributes to the responsive, firmer feel.
  • NanoCoil layer — 1,356 coils: Small comfort coils add contouring response closer to the sleeping surface.
  • High Density Firm Comfort Foam: Adds cushioning while maintaining a supportive character.
  • Marshall Encased Coil System — three zones, 704 coils: Individually encased support coils arranged in a zoned design.
  • High Density Foam Encasement: Reinforces the mattress perimeter.
  • High Density Firm Base Foam: Provides a stable foundation beneath the support system.

Is this your kind of comfort?

Put the Royal on your list if you enjoy a firmer mattress with cushioning at the surface and a responsive feel when you move.

What to feel in the showroom

Bring your partner along so you can both experience the support, edge feel, and movement across the bed. Try your usual sleeping position and compare a softer Reserve model before making the final choice.
