This ultimate 12-inch extra firm king mattress features a dark blue quilted cover and is designed to deliver consistent, restful sleep for back, side, and stomach sleepers. Featuring zoned support, cooling gel memory foam, and a breathable surface, it provides targeted comfort while regulating temperature all night.
- 12-Inch Construction: The mattress is 12 inches thick, offering a substantial profile that pairs well with most bed frames, including platform, slatted, and adjustable bases.
- Extra Firm Support: Engineered with a king firm comfort level, it is ideal for sleepers seeking maximum back support and strong mattress stability.
- BestEdge Foam Technology: An extra-deep foam rail encases the perimeter to reduce edge roll-off and maximize the usable sleep surface across the entire bed.
- Zoned Coil System: A high-density coil system provides targeted support zones specifically designed for the lower back and hips, paired with cradled comfort elsewhere.
- Cool Twist Gel Memory Foam: Premium memory foam blended with cooling gel enhances airflow and heat dissipation for a cool, contouring sleep experience.
- PillowSoft Aire Foam: A gently rippling soft foam layer adds enhanced cushioning while promoting continuous airflow through the mattress body.
- Cooling Quilted Cover: A dark blue quilted cover adds a refined look to your bedroom while working with internal layers to help maintain a comfortable sleep temperature for hot sleepers.
- Universal Compatibility: This king size bed seamlessly integrates with traditional frames, box springs, bunky boards, and adjustable frames for easy setup.
The reinforced edges ensure you can sleep comfortably anywhere on the bed, while the zoned support keeps your spine aligned. The breathable memory foam and airflow-promoting layers help hot sleepers maintain an optimal temperature throughout the night for uninterrupted rest.
