Advanced Technology

The Serta iComfortPRO Quilted Ambrose Firm Mattress is engineered for sleepers who want responsive firm support paired with the natural cooling of premium latex foam. To begin with, it brings together a quilted cool-to-the-touch top with graphite-infused True Response™ Latex Foam to deliver restorative sleep night after night.

Next, the feel is decidedly firm. As a firm Serta iComfortPRO mattress, the Ambrose Firm is purpose-built for back and stomach sleepers, making it a strong contender for the best 13-inch firm mattress Serta shoppers can find online.

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 and the quilted CoolFeel Pro™ cover, the result is advanced heat dissipation technology that performs night after night.

Because of this latex-first approach, the bed delivers maximum spinal alignment support, targeted lower back pressure relief, and luxury hotel-quality firmness within a generous 13-inch profile. The result is responsive, durable support that holds its shape over years of use.

Finally, this Serta iComfortPRO Ambrose 13" Firm mattress is backed by a 10-year Serta limited warranty and built to CertiPUR-US certified foam standards. Cloudy Mattress is an authorized Serta mattress retailer, financing is available, and you can add an adjustable bed, a box spring with metal foundation, or old mattress removal at checkout. Customers ready to buy Serta iComfortPRO Ambrose online can shop with confidence here.

Firm feel for back and stomach sleepers

This best 13 inch firm mattress Serta offering is engineered for sleepers who need solid, supportive surfaces that keep the spine aligned through the night.

Four inches of naturally-derived latex foam

Three inches of True Response™ Latex Foam plus one inch of graphite-infused latex deliver a deeply responsive comfort system. Latex is naturally non-toxic, breathable, and longer-lasting than memory foam.

Graphite-infused cooling latex

The graphite-infused latex layer redistributes heat away from the body, working with the breathability of natural latex to drive advanced heat dissipation technology.

Zoned support for spinal alignment

Serta's 5 ZoneResponse™ Design delivers head-to-toe support across five engineered latex zones, anchoring maximum spinal alignment support through every position.

Targeted lumbar pressure relief

The zoned construction places firmer support under the lower back and upper thighs, giving back sleepers and combination sleepers targeted lower back pressure relief without softening the firm overall feel.

Luxurious quilted cover

The CoolFeel Pro™ quilted top delivers the luxury hotel-quality firmness that sleepers expect from a premium-tier Serta mattress, combined with cool-to-the-touch fabric.

Adjustable base compatible

This mattress is an 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 Ambrose Firm sits within the premium Serta iComfortPRO Series.

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.

One inch of PillowSoft® Aire sits just below the quilt. This layer adds initial cushioning against the body and is engineered with a gently rippling design that promotes airflow, keeping the surface breathable.

One inch of support foam follows. This transition layer bridges the cushioning above to the latex comfort layer below, reinforcing the bed's firm feel without softening the surface.

One inch of premium latex foam infused with graphite delivers the cooling heart of the comfort system. The graphite redistributes body heat away from the sleeper, while the naturally derived latex stays responsive and durable.

Three inches of 100% naturally-derived True Response™ Latex Foam form the responsive support layer. This is where the 5 ZoneResponse™ Design lives, with five engineered zones at alternating firmness levels that provide firmer support beneath the lumbar and hip region while keeping shoulders cushioned.

A 7-inch high-density support foam core anchors the 13-inch mattress profile. This foundational layer provides durable, consistent support edge-to-edge, giving the Ambrose Firm its lasting shape and structural integrity.

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

The Ambrose Firm is built to provide firm, supportive surfaces that keep the spine in neutral alignment, which is often helpful for back sleepers and stomach sleepers managing back discomfort. The 5 ZoneResponse™ Design places firmer support beneath the lumbar region, offering targeted lower back pressure relief.

The Ambrose is a latex foam mattress, not a hybrid. It does not contain pocketed coils or innersprings. Its responsive support comes from four inches of naturally-derived latex foam layered over a high-density Serta® Foam Core, all engineered into a quilted 13-inch profile.

The Ambrose is engineered against heat retention. Natural latex foam does not trap heat the way synthetic foams can; the graphite infusion in the comfort layer actively redistributes body heat, and the CoolFeel Pro™ quilted cover feels cool to the touch on contact. Together these deliver advanced heat dissipation technology, so most sleepers should not find it sleeps hot.

Yes. The Ambrose Firm is an adjustable base compatible and works with motorized power foundations, as well as traditional frames, platform beds, slatted frames, bunky boards, and box springs. At checkout on Cloudy Mattress, you can add an adjustable bed, a box spring with a metal foundation, or an old mattress removal service.

Both mattresses are part of the iComfortPRO latex foam line, but they sit at different comfort levels and profiles. The Chelsea is a 12-inch Medium-feel mattress with 2 inches of latex, positioned for combination sleepers who want balanced softness and support. The Ambrose Firm is a 13-inch Firm-feel mattress with 4 inches of latex, positioned for back and stomach sleepers who want a deeper, more responsive support system.
