The Serta iComfortPRO Buckingham Ultra Plush Mattress is engineered for sleepers who want the most luxurious cloud-like comfort Serta builds into the iComfortPRO line. To begin with, it brings together a quilted cool-to-the-touch pillow top with approximately thirteen inches of naturally-derived True Response™ Latex Foam to deliver restorative, hotel-quality sleep night after night.

Next, the feel is the softest in the lineup. As a Serta iComfortPRO Buckingham 16" Ultra Plush model, this mattress targets shoulder, hip, and lower-back pressure relief, making it a leading choice for the best 16 inch mattress for side sleepers with shoulder pain.

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 fabric, the result is advanced thermal regulation for hot sleepers that performs night after night.

Because of this latex-first approach, the bed delivers cloud-like pressure relief for joints, deep body-contouring and spinal support, and ultimate luxury hotel-quality comfort within a substantial 16-inch profile. The result is responsive cradling without the sinking feeling of memory foam, since latex naturally bounces back as you change positions.

Finally, this softest 16 inch luxury Serta mattress is backed by a 10-year Serta limited warranty and built to CertiPUR-US certified materials 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. Customers ready to buy Serta iComfortPRO Buckingham online can shop with confidence here.

Ultra Plush feel built for side sleepers

Serta positions the Buckingham as its softest iComfortPRO model, making it a leading choice as the best 16 inch mattress for side sleepers with shoulder pain.

Approximately thirteen inches of latex foam

Naturally-derived True Response™ Latex Foam delivers Serta's most latex-rich construction in the entire iComfortPRO line. Latex is naturally non-toxic, breathable, and longer-lasting than memory foam.

Graphite-infused cooling latex

Graphite-infused latex actively redistributes body heat away from the sleeper, working with the natural breathability of latex to drive advanced thermal regulation for hot sleepers.

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 latex support for spinal alignment

Serta's 5 ZoneResponse™ Design delivers head-to-toe support across five engineered latex zones, anchoring deep body-contouring and spinal support even within the Ultra Plush feel.

High-loft quilted pillow top

The high-loft quilted pillow top creates the puffy, cloud-like surface aesthetic that defines a premium pillow top mattress, layered over Serta's most responsive latex construction.

Quiet, undisturbed nights

All-latex construction provides maximum 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 materials and proudly Made in the USA, the Buckingham sits within the premium Serta iComfortPRO Collection.

Key Mattress Benefits

6 Layers
Of Cooling
Comfort

The quilted pillow top uses cool-to-the-touch fabric designed to feel refreshing the moment you lie down. This Cold Touch breathable cover fabric forms the soft, puffy top surface that defines an Ultra Plush pillow top mattress.

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

PillowSoft® Aire delivers enhanced cushioning beneath the quilt. Engineered with a gently rippling design, this soft foam layer promotes airflow through the comfort system while deepening the cloud-like cradle that defines the Ultra Plush feel.

Multiple inches of graphite-infused True Response™ Latex Foam form the upper portion of the latex comfort system. The graphite infusion redistributes body heat away from the sleeper, while the naturally derived latex stays responsive, durable, and breathable.

Additional inches of pure True Response™ Latex Foam follow, adding depth to the contouring system. This Premium Responsive Latex Foam layer provides the soft cradle that side sleepers reach for, with natural buoyancy that prevents the trapped feeling of memory foam.

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 softly cushioned, supporting full-body spinal alignment without compromising the Ultra Plush feel.

A latex support core anchors the 16-inch ultra-high profile mattress. Together with the comfort layers, the Buckingham contains approximately thirteen inches of naturally-derived latex foam, making it the most latex-rich mattress in the iComfortPRO line. This responsive core delivers durable, breathable support edge to edge across years of use.

HAVE QUESTIONS?

WE'VE GOT ANSWERS

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

Yes. The Buckingham is Serta's softest iComfortPRO model, and the brand specifically positions it for side sleepers and anyone seeking ultimate softness. The combination of the high-loft pillow top, Cool Twist® gel-infused quilt foam, PillowSoft® Aire, and approximately thirteen inches of latex delivers cloud-like pressure relief for joints at the shoulders, hips, and lower back.

Yes. With a 16-inch ultra-high profile mattress construction, this bed is significantly taller than a standard 10 or 12-inch mattress, so deep-pocket fitted sheets are required. Look for sheets rated to fit mattresses up to 18 inches thick for the best fit, since standard deep-pocket sheets capped at 14 inches may not stay secure.

Buckingham is a latex foam mattress, not a hybrid. It does not contain pocketed coils or innersprings. Its responsive feel and support come from approximately thirteen inches of layered latex foam in both the comfort and support layers, all engineered into a quilted pillow top 16-inch profile. As a Level 3 iComfortPRO model, it is one of the most latex-rich mattresses Serta makes.

The Buckingham is engineered against heat retention on multiple levels. Natural latex foam does not trap heat the way synthetic foams can, the graphite infusion in the latex actively redistributes body heat, the CoolFeel Pro™ quilted cover feels cool to the touch on contact, and Cool Twist® Gel Memory Foam in the quilt adds gel-based airflow and heat dissipation. Together these deliver advanced thermal regulation for hot sleepers.

Yes. The Buckingham Ultra Plush is 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 metal foundation, or old mattress removal service.
