Advanced Technology

The Serta iComfort Aspire Medium Mattress is engineered for sleepers who want a generous 14-inch profile with a balanced, versatile feel. To begin with, it brings together a cool-to-the-touch quilted cover with multiple layers of premium memory foam for restorative, rejuvenating sleep night after night.

Next, the feel sits squarely in the middle of the comfort scale. As a 14 inch medium tight top mattress, the Aspire Medium suits side, back, stomach, and combination sleepers, making it a strong choice for the best 14 inch mattress for side and back sleepers.

Moreover, the cooling system is engineered into every layer. A graphite-infused Perfect Conform™ memory foam layer paired with EverCool® Supreme memory foam and an advanced cooling fabric cover creates a cooling 14 inch medium firm mattress that helps you stay comfortable through the night.

Because of this layered approach, the bed delivers adaptive temperature regulation, a total body support system, and a luxury 14-inch high profile that anchors the bedroom with hotel-quality presence. The result is consistent comfort across every sleeping position and a breathable sleep surface that performs night after night.

Finally, this iComfort Aspire Smooth Medium Tight Top mattress is backed by a 10-year Serta limited warranty and built to CertiPUR-US certified foam standards. Cloudy Mattress is an authorized Serta retailer, financing available through Affirm, and you can add an adjustable bed, a box spring with metal foundation, or old mattress removal at checkout. Customers ready to buy Serta iComfort Aspire online can shop confidently here.

Medium feel for every sleep position

This 14 inch medium tight top mattress suits side, back, stomach, and combination sleepers who want balanced cushioning without sinking too deeply.

Luxurious 14-inch profile

The luxury 14-inch high profile stacks generous comfort foams over a high-density support core, giving the bed a substantial, premium presence.

Graphite-infused cooling

Two inches of graphite-infused Perfect Conform™ Memory Foam drive adaptive temperature regulation, drawing warmth away from the body as you sleep.

Gel-infused pressure relief from EverCool® Supreme

A higher-density luxury memory foam layer cradles the body for pressure point relief, supporting reduced motion transfer for couples at the same time.

Zoned support for spinal alignment

Serta's 5-ZoneResponse™ Foam Design delivers head-to-toe support across five engineered zones, anchoring the total body support system that keeps the spine in alignment.

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 construction

Built with CertiPUR-US certified foam within Serta's proven iComfort Series, the Aspire Medium is purpose-engineered for secure US shipping and long-term durability.

Key Mattress Benefits

5 Layers
Of Cooling
Comfort

The top surface uses cool-to-the-touch fabric designed to feel refreshing the moment you lie down. This advanced cooling fabric cover helps regulate surface temperature so heat does not build up across the night.

Two inches of premium memory foam infused with graphite sit directly below the cover. Graphite is naturally conductive, which is why this layer drives adaptive temperature regulation while contouring and cradling pressure points across the body.

A higher-density luxury memory foam layer follows. It cradles the body for deeper pressure point relief with a softer yet supportive feel, contributing the contouring half of the Aspire Medium's balanced character.

A zoned foam layer with five ergonomically engineered regions sits between the comfort layers and the support core. These zones provide enhanced support beneath the lower back and upper thighs while keeping shoulders and hips cushioned, anchoring the bed's full-body spinal alignment.

A high-density support foam core establishes the 14" Mattress thickness and provides durable, consistent support from edge to edge. This foundational layer underpins every sleep position and rounds out the bed's tight top construction.

WE'VE GOT ANSWERS

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

The Aspire stands at a full 14" Mattress thickness. This generous 14-inch profile is what gives the bed its luxury, hotel-quality presence and allows Serta to stack multiple cooling comfort layers above the support foam core.

Yes. While the Medium version is built for all sleep positions, the combination of graphite-infused Perfect Conform™ Memory Foam and EverCool® Supreme Memory Foam cushions shoulders and hips, which is exactly what side sleepers need to keep the spine in neutral alignment.

The Aspire is engineered against heat retention. The CoolFeel™ quilt cover, two inches of graphite-infused memory foam, and EverCool® Supreme memory foam work together as a breathable sleep surface with adaptive temperature regulation, so most sleepers should not find it sleeps hot. Individual experience can still vary with bedding and room temperature.

This model is built to a Medium firmness rating. Medium sits squarely in the middle of Serta's comfort scale, which makes it suitable for side sleepers, back sleepers, stomach sleepers, and combination sleepers who change positions overnight.

Yes. The Aspire Medium is adjustable base compatible and works with motorized power foundations, as well as traditional frames, platform beds, slatted frames, bunkie 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.
