Harmony Chill 2.0 Firm Foam Mattresses, by Mlily.

The Harmony Chill 2.0 has a medium, supportive feel that allows any sleeper to stay comfortable throughout the night. Its Cooling Knit Fabric Cover keeps the sleeper cool and enhances the capabilities of the interior foams. A unique layer of PCM (phase-changing material) directly under the cover absorbs and releases heat to equalize the temperature.

• Harmony Chill Cooling Knit Fabric Cover: With a very soft-to-the-touch feel and the important ability to let air flow easily, this fabric offers comfort, function, and durability. Its interlaced threads throughout the cover move with you to reduce bunching and create natural air gaps for breathability.
• PCM Coating - Phase Changing Material: PCM stands for Phase Changing Material which means that it can release or absorb body heat to provide passive temperature regulation while you sleep. Your body temperature lowers to induce sleep and raises to wake you up. This coating adds additional cooling technology to our specialty foams to ensure deep sleep without interruption.
• Bamboo Charcoal Memory Foam: This foam offers superior support by adapting to your micro-pressure points and it has an open cell structure that helps keep the bed cooler. While the infused ingredients are naturally antibacterial, bamboo charcoal also naturally reduces moisture and odors.
• Performance Foam: "This foam is all about versatility. It mixes qualities of durability, flexibility, and adaptability into a single memory foam. Performance Memory Foam is often used as a mid-section foam due to its ability to both fully support the more breathable foams above it while allowing them to gently contour to the sleeper."
• Flex Support Base Foam: Flex Support Foam is often the bottom layer of our mattresses. A mattress needs to provide the support needed to keep the spine aligned so the sleeper’s muscles relax instead of tightening to compensate. This high-grade foam completes the bottom of the mattress to provide long-lasting durability and support of the top layers.
