Combining firm, restorative support with innovative foam technology, the Capetown mattress delivers a replenishing sleep surface that conforms to your body to provide targeted pressure point relief. Topping the deeply supportive Custom Support Flex 704 coil system is a combination of PillowSoft foam, Support foam and Cool Twist gel memory foam. While each type of foam provides firm, body-contouring comfort, the advanced Cool Twist gel memory foam also works to dissipate excess body heat to maintain a cool, refreshing sleep environment that promotes deep, uninterrupted sleep. Meanwhile, the Total Edge foam encasement expands the usable sleep space so that you can enjoy the firm support of this restorative mattress all the way to the mattress edge. 10 Year Warranty.
