Extra firm feel for back and stomach sleepers
This mattress is built for sleepers who need solid, unyielding support, making it a strong candidate as an extra-firm Serta mattress for back pain management.
Naturally-derived latex foam
Two inches of True Response™ Latex Foam deliver a responsive, durable comfort surface that adapts to movement without sinking. Latex is naturally non-toxic and breathable.
Naturally cool sleep surface
Latex does not trap heat the way synthetic foams can. Combined with the quilted cool-to-the-touch cover, this delivers advanced thermal regulation cooling for sleepers who run warm.
Zoned support for spinal alignment
Serta's 5 ZoneResponse™ Design provides head-to-toe support across five engineered latex zones, anchoring maximum spinal alignment support through every position.
Long-lasting durability
Latex foam is naturally durable and resists body impressions over time. The supportive base layer provides a zero-sag, durable sleep surface that maintains its feel for years.
Quiet, undisturbed nights
All-foam construction with zoned latex helps minimize partner movement, supporting restful sleep for couples.
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 Granby sits within the premium Serta iComfortPRO Collection.
Key Mattress Benefits
5 Layers
Of Cooling
Comfort
The top surface uses a cool-to-the-touch quilted fabric designed to feel refreshing the moment you lie down. This quilted top helps you fall asleep more easily by lowering the surface temperature on contact.
A layer of PillowSoft® Foam sits below the cover, providing enhanced cushioning that softens the surface slightly without compromising the extra firm support beneath. This thin comfort layer protects against pressure points while keeping the overall feel firm.
Two inches of 100% naturally-derived latex foam follow. This is the heart of the iComfortPro design. Latex is responsive, durable, breathable, and non-toxic by nature, giving the bed both its bounce-back feel and its temperature-regulating properties.
The latex layer is engineered with five distinct support zones that alternate firmness across the bed. These zones provide firmer support under the lumbar and hip region while contouring the body's natural curves, delivering targeted heavy-duty pressure relief without softening the extra firm feel.
The base layer establishes the 11.5-inch mattress profile and provides durable, consistent support edge to edge. This high-density foundation anchors the entire bed and is what gives the Granby its zero-sag, durable sleep surface and long-term shape retention.
The benefits
5 comfort zones
With alternating levels of firmness, ergonomica support zones are designed to keep your body in natural alignment throughout the night.
Providing enhanced support where the body naturally curves (lower back, upper thigh) while ensuring comfort where the body touches the mattress the most (shoulders, hips, lower legs).
THE COMFORT LAYER YOU'LL LOVE
What is a pillow top?
A pillow top is an additional layer of padding sewn into the top of your mattress. This provides a softer sleeping surface while still offering breathability and support from the mattress below.
Pillow tops create a puffy, pillow-like appearance. The padding might be regular foam, memory foam, latex, fiberfill, cotton or wool, depending on the mattress.
