Hey there, hot sleepers! Beat the bedtime heat with the 11" Cooling Lumbar Zone Hybrid mattress from Northern Nights.

Thanks to careful construction with layers of the latest sleep technologies, this mattress is a breakthrough for bedtime comfort. Let's dissect the design. A CarbonCHILL graphite-infused layer helps draw heat away from the body, promoting a cooler sleep environment. Next, a DREAMfoam ventilated gel foam layer offers better airflow and more conforming pressure relief than conventional polyurethane foam. There's also the responsive coil unit that consists of individually wrapped steel coils that help reduce motion transfer and pressure compared to a conventional bonnell spring unit. But it's the top layer that is the coolest. The cover's fabric features cooling fibers that deliver an instant cool-to-the-touch surface. It also wicks moisture away from your skin and transports it through the fabric to dissipate quickly, creating a drier sleep environment. Plus, it's equipped with Spinal Zone Quilt technology.

Your 2026 resolution for a superior sleep sanctuary is effortlessly achievable with this remarkable mattress. From Northern Nights® Bedding.
