Firm feel for back and stomach sleepers
Serta specifically positions the Kingston for stomach sleepers, back sleepers, and anyone who prefers a firm feel that delivers maximum spinal alignment and support.
Ten inches of premium latex foam
Ten full inches of graphite-infused True Response™ Latex Foam deliver Serta's most latex-rich comfort and support system. Latex is naturally non-toxic, breathable, and longer-lasting than memory foam.
Graphite-infused cooling latex
The graphite-infused latex redistributes body heat away from the sleeper, working with the natural breathability of latex to drive advanced thermal regulation cooling.
Zoned support for spinal alignment
Serta's 5 ZoneResponse™ Design delivers head-to-toe support across five engineered latex zones, anchoring targeted pressure point cushioning at the lumbar while keeping shoulders supported.
Responsive, durable latex feel
Latex bounces back as you change positions rather than holding an impression, providing responsive latex bounce and relief night after night.
Quiet, undisturbed nights
All-latex construction provides motion isolation that dampens partner movement, helping minimize disturbance across the bed.
Adjustable base compatible
This mattress is adjustable base compatible, so you can pair it with a power foundation for elevated head or foot positions.
Certified, trusted materials
Built with CertiPUR-US certified foam and proudly Made in the USA, the Kingston Firm sits within the premium Serta iComfortPRO Collection.
6 Layers
Of Cooling
Comfort
The quilted top uses cool-to-the-touch fabric designed to feel refreshing the moment you lie down. This Cold Touch breathable cover fabric helps regulate surface temperature so heat does not build up across the night.
A layer of PillowSoft® Foam sits just below the quilt, providing enhanced cushioning that protects against pressure points and gives the surface a slight initial softness without compromising the firm support beneath.
PillowSoft® Aire with its gently rippling design adds breathability and additional cushioning. This layer promotes airflow through the comfort system while reinforcing the bed's cooling architecture.
Ten full inches of graphite-infused True Response™ Latex Foam form the heart of the Kingston Firm. This is Serta's most latex-rich construction at this comfort level. Naturally derived from rubber trees, this latex stays responsive, durable, and breathable, while the graphite infusion actively redistributes body heat away from the sleeper.
The latex layer is engineered with five distinct support zones at alternating firmness levels. These zones provide firmer support beneath the lumbar and hip region while keeping shoulders and lower legs cushioned, supporting maximum spinal alignment and support across every sleep position.
The base layer establishes the 14-inch mattress profile thickness and provides high-density foam encased edge support at the perimeter. This foundation reinforces the bed's structural integrity and delivers strong edge stability for sit-down comfort and full-mattress usability.
