Medium feel for versatile sleep positions
This best medium firm quilted mattress Serta offering suits side, back, stomach, and combination sleepers who want balanced cushioning without sinking deeply.
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.
Graphite-infused cooling latex
The comfort layer is infused with graphite, which is naturally conductive and redistributes heat away from the body, driving advanced heat dissipation technology beyond what latex alone provides.
Zoned support for spinal alignment
Serta's 5 ZoneResponse™ Design provides head-to-toe support across five engineered latex zones, supporting balanced pressure relief and support through every position.
Luxurious quilted cover
The CoolFeel Pro™ quilted top delivers the luxury hotel-quality quilted comfort that sleepers expect from a premium-tier Serta mattress, combined with cool-to-the-touch fabric.
Quiet, undisturbed nights
Latex and foam construction provides motion isolation for light sleepers, helping minimize partner movement transfer across the bed.
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 Chelsea sits within the premium Serta iComfortPRO Collection.
7 Layers
Of Cooling
Comfort
A 1.25-inch quilted top layer 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 high-density cushioning foam sits below the quilt. This layer adds initial softness against the body while supporting the cover and maintaining the quilted top's shape over years of use.
A second one-inch PillowSoft® Aire layer follows, engineered with enhanced airflow for breathability. It deepens the surface cushioning that defines the Medium feel and contributes to the bed's restorative, deep sleep surface.
One inch of premium latex foam infused with graphite is the heart of the comfort system. Naturally derived from rubber trees, this latex layer is responsive and durable. The graphite infusion redistributes body heat away from the sleeper, supporting the bed's cooling system.
A 7-inch layer of 100% naturally-derived latex forms the responsive support core. This is where the 5 ZoneResponse™ Design lives, with five engineered zones at alternating firmness levels that deliver firmer support beneath the lumbar and hip region while cushioning shoulders and lower legs.
A one-inch foam core base with Ultimate Edge Support reinforces the perimeter of the bed, giving it strong edge stability for sit-down comfort and full-mattress usability.
The final support foam layer anchors the 12-inch mattress profile and provides the durable, consistent foundation that holds the entire bed in place across years of use.
