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.

Liquid Gel Flex Foam

This cooling foam is the third in our line of Flex Foams. It is a more breathable version of our Flex Comfort Foam with liquid cooling gel swirled into the foams cellular-like structure. This allows it to keep the sleeper cooler and more air to circulate through the foam layers around it.

Egg Crate Embossed Foam

This embossed foam is an egg crate pattern that can be added to any foam. The embossed pattern provides additional plushness to the above layers. The undulations in the foam not only offer uniform support but also airflow to lower the temperature of the surrounding foams.

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.

How to setup your new MLILY mattress
