Take a look inside

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

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.
