Advanced Technology

The Serta iComfortPRO Canterbury Plush Mattress is engineered for sleepers who want Serta's most latex-rich construction paired with a soft, cradling Plush feel. To begin with, it brings together a quilted cool-to-the-touch top with a full twelve inches of graphite-infused True Response™ Latex Foam to deliver cloud-like, restorative sleep night after night.

Next, the feel is decidedly soft. As a Serta iComfortPRO 15 Inch Plush model, the Canterbury targets shoulder, hip, and lower-back pressure relief, making it a leading choice for the best 15 inch plush mattress for side sleepers.

Moreover, the cooling system uses one of nature's best temperature regulators. Latex foam from rubber trees is naturally breathable and does not trap heat the way synthetic foams can. Paired with graphite infusion, gel-infused quilt foam, and the Cold Touch breathable cover, the result is advanced heat regulation technology that performs night after night.

Because of this latex-first approach, the bed delivers maximum pressure point relief, natural latex cooling and bounce, and a luxury high-profile hotel feel within a substantial 15-inch profile. The result is responsive contouring that adapts to every position without the sinking feeling of memory foam.

Finally, this luxury plush latex mattress is backed by a Serta 10-year limited warranty and built to CertiPUR-US certified foam standards. Cloudy Mattress is an authorized Serta mattress retailer, financing available now, and you can add an adjustable bed, a box spring with metal foundation, or old mattress removal at checkout.

Plush feel built for side sleepers

Serta positions the Canterbury Plush for sleepers seeking softer comfort, making it a leading choice as the best 15 inch plush mattress for side sleepers.

Twelve inches of premium latex foam

Twelve full inches of graphite-infused True Response™ Latex Foam form the heart of this Responsive Latex Foam layer construction. This is one of the most latex-rich beds in the entire iComfortPRO lineup.

Graphite-infused cooling latex

The graphite-infused latex actively redistributes body heat away from the sleeper, working with natural latex breathability to drive advanced heat regulation technology.

Gel-infused quilt for surface cooling

Cool Twist® Gel Memory Foam in the quilt adds enhanced airflow and heat dissipation, reinforcing the cooling system from the very top layer inward.

Zoned support for spinal alignment

Serta's 5 ZoneResponse™ Design delivers head-to-toe support across five engineered latex zones, supporting the spine even within the deep cushioning quilted top Plush feel.

Responsive, durable latex feel

Latex bounces back as you change positions rather than holding an impression, providing natural latex cooling and bounce night after night.

Quiet, undisturbed nights

Latex construction provides superior motion isolation for couples, dampening partner movement so you can sleep through the night undisturbed.

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 Canterbury sits within the premium Serta iComfortPRO Collection.

Key Mattress Benefits

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 helps regulate surface temperature so heat does not build up across the night.

Cool Twist® Gel Memory Foam is swirled into the quilt construction. The cooling gel improves airflow and heat dissipation from the top surface inward, reinforcing the cooling system before sleepers even reach the latex below.

PillowSoft® Aire delivers enhanced cushioning beneath the quilt. Engineered with a gently rippling design, this layer promotes airflow through the comfort system and deepens the soft, cradling feel that defines the Plush model.

Multiple inches of graphite-infused True Response™ Latex Foam form the upper portion of the comfort system. Naturally derived from rubber trees, this latex is responsive and durable, while the graphite infusion actively redistributes body heat away from the sleeper.

The latex layers are 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, delivering full-body spinal alignment without compromising the Plush feel.

A latex support core anchors the 15-inch mattress profile thickness. Together with the comfort layers, the Canterbury contains twelve full inches of naturally-derived latex foam, making it one of the most latex-rich mattresses in the iComfortPRO line. This responsive core delivers durable, breathable support edge to edge across years of use.

WE'VE GOT ANSWERS

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

Yes. Serta positions the Canterbury Plush specifically for side sleepers and anyone seeking softer comfort. The combination of Cool Twist® gel-infused quilt foam, PillowSoft® Aire, and twelve inches of latex delivers maximum pressure point relief at the shoulders, hips, and lower back, which is exactly what side sleepers need to keep the spine aligned.

The Canterbury is engineered against heat retention on three levels. Natural latex foam does not trap heat the way synthetic foams can, graphite infusion in the latex actively redistributes body heat, and the CoolFeel Pro™ quilted cover paired with Cool Twist® Gel Memory Foam delivers cool-to-the-touch surface contact. Together these support advanced heat regulation technology.

The Canterbury is a latex foam mattress, not a hybrid. It does not contain pocketed coils or innersprings. Its responsive feel and support come from twelve inches of layered latex foam in both the comfort and support layers, all engineered into a quilted 15-inch profile. As a Level 3 iComfortPRO model, it is one of the most latex-rich constructions Serta makes.

If you compare Serta iComfortPRO Canterbury vs Dartmouth, choose Canterbury for the most latex-rich, responsive feel and choose Dartmouth for the puffier pillow top profile with a foam-core foundation.

Yes. With a 15-inch mattress profile thickness, this bed is taller than a standard 10 or 12-inch mattress, so deep-pocket fitted sheets are recommended. Many deep-pocket sheets are rated to fit mattresses up to 16 or 18 inches thick, which works well for this model.
