Moisture Wicking Fabrics

Proper Spinal Alignment

King Koil is the only mattress manufacturer that is endorsed by the International Chiropractors Association (ICA) to help promote proper spinal alignment and a healthier night’s sleep.

Rapid Response Foam

Enjoy the feeling of “sleeping on” our mattress and not the sinking, “sleeping in it” feeling with our iNergex3 Foam technology. Our iNergex3 foam is an energetic foam that is a highly breathable, cool and responsive. This pressure relieving foam conforms like memory foam but is highly resilient like latex, giving you the best performance of both foam technologies.

Reduced Motion Disturbance

Enjoy an undisturbed night's sleep with our individually encased coil system. These independently wrapped coils conform to your body's curves while reducing any sense of motion if your partner decides to move or get out of bed.

Adjustable Base Friendly

Enjoy an even healthier night's sleep with this adjustable base compatible mattress design.

Moisture Wicking

Joma Wool® is renowned as a luxurious, flame resistant, water repellent, non-allergenic fiber, New Zealand Joma wool is used in our mattress to maximize your comfort level and ensure breathability. The Joma wool provides a natural stretch to enhance your overall comfort for a more restful sleep, like an affectionate hug.

Enhanced Body Conformance

Micro-Encased Coil Technology - Coil-on-Coil technology for the ultimate in support and conformance. The bottom layer of coils provide unparalleled support, while the top layer of mini-coils conforms faithfully to the body - helping to ensure a restful and refreshing night’s sleep.

Tencel™ Fibers

The mattress comfort surface incorporates Eco-friendly Tencel fibers, derived from sustainable wood sources that promote the body’s natural thermal regulating mechanism, deter bacterial growth and enhance breathability by efficiently absorbing moisture. Tencel is durable yet gentle on the skin to provide long-lasting comfort and an optimal skin climate.

Pressure Equalization

King Koil’s Perfect Contour® Reaction Coil System maximizes positive pressure by increasing support to your lower back while minimizing negative pressure around your hips and shoulders, also known as pressure equalization. This approach is ideal for blood circulation and muscle relaxation to reduce tossing and turning, while maintaining a healthy night time sleeping posture.

Temperature Regulation

ThermoGraph™ - The ultimate blend of three rapid heat transferring materials: Open-Cell Breathable Memory Foam, Gel Memory Foam and Graphite are fused together and then enhanced with ThermaPhase. This incredible fusion quickly absorbs body heat and immediately transfers it through the open cell structure of the foam, leaving the comfort surface the optimal sleeping temperature quicker than any other foam.

Pressure Relieving Support

Natural Conform Latex provides the ultimate in conforming support and durability and is naturally derived from the rubber tree making it anti-microbial to prevent bacteria, mold and mildew growth.
