Harmony+ Firm Foam Mattresses, by Mlily.

The Harmony + is a medium-firm mattress that features foam layers specially designed to conform to the weight and pressure of every individual. Its cover is soft to the touch and exceptionally breathable. The foam layers provide maximum air circulation and temperature regulation to keep the sleeper cool and supported through the night.

• Medium firm
• Increased breathability
• Regulates temperature
• Harmony+ Double Jacquard 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.
• Gel AeroFusion™ Memory Foam: This memory foam is generously infused with a cooling gel. It keeps all of the positive properties of memory foam, like contouring and conforming to the sleeper, while mitigating temperature issues with the gel infusion.
• 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."
