Expert Review by Jed
The California King size Sealy Posturepedic Response Premium Warrenville IV Cushion Firm Pillow Top Mattress is one of the most comfortable models in the line for those who enjoy the initial softness of a pillow top paired with firm underlying support. In addition to superb comfort, this mattress also features a wide array of upgrades from the previous generation III Warrenville model, including the coil system, foam quality, quilt, and edge support.

Starting at the top, the first change is located in the SupremeLoft Cover with MoistureProtect and AllergenProtect Technology used in the quilt. This amazing fabric is brilliantly engineered to draw moisture away from your body to protect against dust mites and dander, ensuring a fresh sleeping space. Next, each of the comfort materials implemented in the Warrenville IV are now CertiPUR-US certified to meet or exceed the highest quality standards in bedding today. Comfort layers include Sealy Cushion Air Ultra Soft Foam, which provides the initial contouring and softness of a pillow top, and it also encourages better airflow. Next, the layer of Sealy Cushion Extra Soft Foam delivers deep pressure relief to aid in eliminating tossing and turning while encouraging good blood circulation. A layer of Sealy Support Foam keeps the mattress from feeling too soft, and it helps the mattress achieve a firm underlying feel. Lastly, an added layer of Sealy Support Foam further contributes to the firm underlying feel. Posturepedic Technology is incorporated in the center third to bolster support. This is done with the help of the SealyCool Gel Memory Foam in the center third in addition to the zoned design used in the coil system. Speaking of the coil system, the Sealy Response Pro HD Encased Coil System has a higher coil count than the previous generation, and it also delivers zoned support to the lower back. The individually wrapped design closely contours to the unique curves of the body while supplying solid support. This coil system is fully compatible with an adjustable base, and it provides impressive motion isolation. This is particularly nice for couples because when movement occurs on one side, the other side stays undisturbed. Last but not least, the DuraFlex Edge offers a great edge support and consistency in comfort, even if you rest all the way at the edges. This is a big upgrade from the already good foam encasement found in the last model.

To conclude, if you prefer a firm underlying feel but want enough padding to sink in a bit, the California King size Sealy Posturepedic Response Premium Warrenville IV Cushion Firm Pillow Top Mattress is one of the best choices available on our site. The numerous improvements from the previous generation make this model an even better value than before, and it's dependably made to last you the next 10 years or more.
