The South Bay Active Align Reactive Copper Mattress is engineered specifically for active sleepers who need recovery-focused rest in a balanced medium-firm 10-inch profile.

Cloudy Mattress is the authorized South Bay retailer for this product, so every purchase comes with trusted sourcing and the full manufacturer's warranty.

The feel sits firmly on the medium-firm side of the comfort scale, making it well-suited for back, stomach, and side sleepers alike. Because of this responsive support, it stands out as one of the best copper mattresses for back pain options for athletes and active individuals.

Inside, five engineered foam layers work together, beginning with copper-infused memory foam that delivers cooling and antimicrobial benefits at the sleep surface. This copper-infused memory foam mattress uses copper's natural conductivity to draw heat away from the body, creating a 10-inch medium-firm cooling mattress experience.

Furthermore, the fresh sleep environment is supported by copper's natural antimicrobial properties, helping resist odors and microbes through the night. A 2-inch reactive foam technology layer beneath delivers latex-like bounce-back support that adapts to your body without the deep sink-in feel of traditional memory foam.

This design encourages targeted spinal alignment and supports muscle recovery, ideal for fitness enthusiasts and combination sleepers. A M-Guard edge support system reinforces the perimeter, adding roughly 20% more usable sleeping space and a steadier feel along the sides of the bed.

Beneath the comfort layers, a 2-inch Support Foam plus a 5-inch Air Grid base form the high-density foam core with airflow channels for breathability and adjustable-base flexibility. Together, this zoned support mattress, queen size and other variants are designed to deliver restorative sleep support and pressure point relief night after night.

At 10 inches and fully adjustable-base compatible, this medium firm 10-inch mattress pairs seamlessly with any modern foundation. The mattress arrives via Mattress-in-a-box delivery, compressed and rolled for convenient setup, and is backed by a 10-year manufacturer's warranty.

Key Mattress Benefits
Active Align Reactive Copper Zoned Foam - Patented Edge Support Medium Firm 10 inch Mattress By South Bay

6 Layers
Of Cooling
Comfort

This top layer is the copper-infused memory foam that delivers cooling and antimicrobial benefits at the sleep surface. The copper helps draw heat away from the body and naturally resists microbes for a fresher rest.

This second layer uses reactive foam technology to deliver a latex-like bounce-back feel. As a result, sleepers benefit from responsive support that adapts to movement without the deep sink-in of traditional memory foam.

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

This middle layer adds reinforcement and structural support beneath the reactive comfort layers. It helps deliver a consistent feel across the entire mattress while transitioning into the base.

This bottom layer forms the high-density foam core of the mattress with articulated cuts that promote airflow through the base. Furthermore, the grid construction adds flexibility, making the mattress an excellent match for adjustable bases.

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.

The Active Align is designed with reactive foam and a layered support system that promotes targeted spinal alignment. Many sleepers find this combination helpful for general comfort and back support, especially active individuals recovering from physical activity. However, anyone with chronic or diagnosed back conditions should consult a medical professional before making a purchase decision.

Yes, 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 and a more breathable sleep experience, especially valuable for hot sleepers.

Zoned foam support refers to a mattress design where different layers or sections are engineered to provide varied levels of firmness and contouring across the body. In the Active Align, the combination of copper memory foam, reactive foam, support foam, and Air Grid base works together to deliver pressure relief at the shoulders and hips while maintaining firmer support beneath the core and lower back.

The patented edge support system reinforces the perimeter of the mattress with denser foam framing. This expands the usable sleeping surface by roughly 20%, provides a steadier sitting edge when getting in and out of bed, and helps extend the mattress's overall longevity by reducing edge wear.

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 a metal foundation as an add-on at checkout.
