The South Bay 14 Inch Copper Gel Hybrid Mattress combines plush, conforming comfort with the durable support of a foam-encased coil system in a luxurious 14-inch profile. Cloudy Mattress is the authorized South Bay retailer for this product, so every purchase is backed by trusted sourcing and the full manufacturer warranty.

The feel sits on the plush, soft side of the comfort scale, delivering the cloud-like cradling that side and back sleepers often seek. Because of this conforming top layer, it stands out among the best 14 inch plush mattresses for side sleepers options for pressure relief at hips and shoulders.

Inside, five engineered components work together, starting with a generous 3-inch copper-infused viscoelastic memory foam top that delivers cooling and antimicrobial benefits. This plush 14-inch copper infused mattress uses copper's natural conductivity to help regulate temperature and dissipate body heat through the night.

Furthermore, the antimicrobial heat-conducting mattress layers support a fresher, cleaner sleep surface that resists odor buildup. Beneath the comfort layers, foam-encased coils form the supportive core, delivering responsive lift with the gentle bounce typical of hybrid mattress construction technology.

This combination delivers a deep restorative luxury sleep experience that balances plush surface contouring with reliable underlying support. A patented edge support system reinforces the perimeter, extending the usable sleeping area by roughly 20% and providing stability when sitting along the sides.

At a full high profile plush hybrid mattress profile of 14 inches, this design is adjustable base compatible for personalized comfort customization. Additionally, it arrives compressed and rolled for easy mattress-in-a-box delivery, and is backed by a 10-year limited warranty.

Plush Cloud-Like Comfort

A generous 3-inch copper-infused viscoelastic memory foam top delivers cloud-like plush comfort that feels ideal for side and back sleepers.

Cooling Copper Technology

Foam-Encased Coil Support

Foam-encased coils deliver responsive lift and stable support, blending the bounce of innersprings with the contouring of memory foam.

Patented Edge Support

An M-Guard patented edge support system reinforces the perimeter, adding 20% more usable sleeping space and a steadier sitting edge.

CertiPUR-US Certified Foams

Built with CertiPUR-US certified foam layers made without formaldehyde, phthalates, heavy metals, or ozone depleters.

Key Mattress Benefits

Hybrid Copper-Gel Infused Memory Foam 14 inch Plush Full Encasement Mattress By South Bay

6 Layers
Of Cooling
Comfort

This top layer is the copper-infused viscoelastic memory foam that delivers a plush, cradling feel at the sleep surface. The copper helps conduct heat away from the body and provides natural antimicrobial properties for a fresher rest.

This middle layer functions as an excellent transitional foam between the top comfort layer and the coil core. As a result, it smoothly balances plush conformity with structural support throughout the mattress.

A reinforced perimeter is built into the mattress to extend the usable sleeping area by roughly 20% and improve longevity. This system also provides a stable sitting edge when getting in and out of bed.

This core layer is built from foam-encased coils that deliver responsive support with a gentle bounce. The foam encasement reinforces stability across the entire perimeter and core of the mattress.

This final layer adds extra conforming comfort beneath the coil system. It helps round out the overall feel and contributes to the plush, luxurious profile of the mattress.

The exterior cover unzips for easy laundering and helps reduce allergens with regular washing. Its breathable design complements the copper-infused cooling system at the surface of the mattress.

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

Yes, the 14-inch hybrid is well-suited for side sleepers. The plush 3-inch copper-gel memory foam top cradles the shoulders and hips where side sleepers need the most contouring, while the foam-encased coil base provides the underlying support to keep the spine in healthy alignment.

A foam-encased coil mattress, sometimes referred to as full-encasement, surrounds the coil unit with a perimeter of dense foam. This adds significant edge stability, expands the usable sleeping surface, and helps extend the mattress's overall lifespan by reducing wear at the edges.

Copper is a naturally heat-conductive metal, so infusing it into the top memory foam layer helps draw warmth away from the body. This conductive effect supports cooler surface temperatures, making it especially helpful for hot sleepers and those who experience night sweats.

A box spring is not required. The mattress can be placed on a continuously solid surface, an adjustable base, or slats spaced no more than two inches apart. Cloudy Mattress also offers an optional box spring with metal foundation as an add-on at checkout.

Yes, all foam layers in this mattress are CertiPUR-US certified. They are made without formaldehyde, phthalates, ozone depleters, heavy metals, PBDEs, or listed Tris flame retardants, and they meet low-VOC standards for healthier indoor air quality.
