Product Information


This firm mattress features a 532 Mira-Coil innerspring system for optimal body support and reduced motion transfer from one sleeper to the other. The innerspring also features foam encasement to provide additional firmness at the edges of the mattress to prevent roll-off. The upholstery layers include Gentle Support Aire, an ultra-soft layer of foam that provides enhanced cushioning and promotes airflow to help reduce heat build-up, plus a 1 layer of Support Foam that provides a firm, yet supportive, feel to the mattress.


  • Gentle Supportâ„¢ Aire - This ultra-soft foam provides enhanced cushioning for exceptional comfort. Plus, its unique rippling design promotes enhanced airflow to help reduce heat build-up.
  • Gel Activeâ„¢ Foam - This gel-infused foam gently cradles your body and helps dissipate heat.
  • Foam Encasement - A border of high-density foam encases the innerspring system to provide additional edge support. This expands the sleeping surface all the way to the edge and helps prevent sagging and rolling off the sides of the mattres
  • HI IFD Support Foam - HI IFD Support Foam combines gentle cushioning with extra support, for more firmness at the sleep surface.
