This firm mattress gets its support from a 391 PostureSmart® innerspring that provides excellent support for your entire body. The comfort 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.
HI IFD Support Foam combines gentle cushioning with extra support, for more firmness at the sleep surface.
The PostureSmart™ Innerspring uses an offset coil design to ensure maximum flexibility and responsiveness to the contours of your body while you sleep. It has an increased surface coverage compared to other value-priced innersprings, helping to provide enhanced conformability, comfort and support. Plus, the alternating coil design enhances stability while strengthening the mattresses edges.
