Within Serta's Collection of Great Value Mattresses, these Individually Wrapped Coil Mattresses stand out. Each coil works independently, providing contouring and cradling support while minimizing motion from partner movement. Layers of deluxe foam, including Serta® PillowSoft™ Foam and Serta® Support Gel Foam, provide cushion and comfort for that just right feeling. This firm mattress is good for a back or stomach sleeper.
