Advanced Technology

The Serta iComfort Aspire Plush 14 Inch Mattress is engineered for sleepers who want a luxurious, deeper profile paired with a soft, cradling surface. To begin with, it brings together a cool-to-the-touch quilted cover with multiple layers of premium memory foam to deliver restorative, rejuvenating sleep night after night.

Next, the feel is decidedly soft. As a soft 14 inch Serta mattress, the Aspire Plush is purpose-built for shoulder, hip, and lower-back pressure relief, making it a top contender for the best 14 inch soft mattress for side sleepers.

Moreover, the cooling system is engineered into every layer. Two inches of graphite-infused Perfect Conform™ Memory Foam combined with EverCool® Supreme memory foam and a breathable smooth top cover fabric create a cooling plush mattress for shoulder pain relief that helps you stay comfortable throughout the night.

Because of this layered approach, the bed delivers deep pressure point relief, advanced thermal regulation technology, and a luxury hotel-style sleep height that anchors the bedroom with substantial presence. The result is consistent comfort and targeted cushioning for hips and shoulders in every restorative night.

Finally, this iComfort Aspire Smooth Plush Mattress is backed by a 10-year Serta limited warranty and built to CertiPUR-US certified foams standards. Cloudy Mattress holds authorized Serta retailer status, financing available now through Affirm, 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

This soft 14-inch Serta mattress softens the surface where shoulders and hips press in, easing pressure where side sleepers need it most.

Luxurious 14-inch hotel-style profile

The luxury high-profile plush mattress USA customers shop online stacks generous comfort foams over a high-density support core, giving the bed a premium, luxury hotel-style sleep height.

Two inches of graphite-infused cooling foam

Premium graphite-infused memory foam drives advanced thermal regulation technology, drawing warmth away from the body as you sleep.

EverCool® Supreme high-density comfort

A luxury memory foam layer with enhanced airflow cradles the body for deep pressure point relief while keeping the sleep surface breathable.

Zoned support for spinal alignment

Serta's 5-ZoneResponse™ Foam Design delivers head-to-toe support across five engineered zones, keeping the spine aligned even with the Plush feel above.

Quiet, undisturbed nights

All-foam construction provides undisturbed sleep motion isolation, so partner movement is dampened rather than transferred 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 foams and proudly made in the USA, the Aspire Plush sits within the established Serta iComfort Collection.

Key Mattress Benefits

6 Layers
Of Cooling
Comfort

The top surface uses a luxurious, silky, cool-to-the-touch fabric designed to feel refreshing the moment you lie down. This breathable, smooth top cover fabric helps regulate surface temperature so heat does not build up across the night.

A 2.5-inch high-density luxury memory foam layer sits directly beneath the cover. Engineered with enhanced airflow, this layer cradles the body for deep pressure point relief with a softer yet supportive feel, defining the Plush comfort feel of the bed.

Two inches of premium memory foam infused with graphite follows. Graphite is naturally conductive, which is why this layer drives advanced thermal regulation technology, drawing body heat away while contouring around shoulders, hips, and the lower back.

A one-inch transition layer bridges the soft comfort foams above to the support system below. It deepens the targeted cushioning for hips and shoulders that side sleepers reach for, while preventing the body from sinking too far into the bed.

A 1.5-inch zoned foam layer follows, with five ergonomically engineered regions at alternating firmness levels. These zones provide enhanced support beneath the lower back and upper thighs while keeping shoulders and hips cushioned, supporting full-body spinal alignment without losing softness above.

A 7-inch high-density support foam core anchors the 14-inch mattress profile. The Ultimate Edge encasement reinforces the perimeter, giving the bed strong edge support for sit-down stability and rounding out this all-foam construction.

HAVE QUESTIONS?

WE'VE GOT ANSWERS

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

Yes. Plush is the softest comfort level in the Aspire 14-inch lineup, and Serta specifically positions it for side sleepers because the surface gives extra cushioning at the shoulders, hips, and lower back. The combination of EverCool® Supreme Memory Foam and graphite-infused Perfect Conform™ Memory Foam delivers targeted cushioning for hips and shoulders where side sleepers tend to feel pressure first.

Yes. With a 14-inch mattress profile, this bed is taller than a standard 10 or 12-inch mattress, so deep-pocket fitted sheets are recommended. Most deep-pocket sheets are rated to fit mattresses up to 14 or 16 inches thick.

The Aspire Plush does not actually use a system called UltraCold. Its cooling comes from three layers working together. The CoolFeel™ Fabric cover feels cool to the touch on contact. Two inches of graphite-infused Perfect Conform™ Memory Foam draw heat away from the body through graphite's natural conductivity. The EverCool® Supreme Memory Foam adds enhanced airflow for surface breathability. Together, these layers create advanced thermal regulation technology without compromising the Plush feel.

The Aspire Plush is an all-foam memory foam mattress, not a hybrid. It does not contain pocketed coils or innersprings. The 14-inch profile is built entirely from layered memory foams over a high-density Serta® Foam Core, with an Ultimate Edge foam encasement reinforcing the perimeter.

The Aspire Plush is built on a high-density Serta® Foam Core anchored by an Ultimate Edge foam encasement, which provides durable support and reinforced edges. For larger body types, individual experience with a Plush feel varies because soft mattresses naturally compress more under weight. Serta recommends pairing the mattress with a sturdy adjustable base or proper foundation with center support for queen and king sizes.
