MLILY® Harmony Chill 3.0 Gel Memory Foam 13" Plush Tight Top Full Mattress in a Box

Best-selling plush foam mattress with five layers of chilly temperature-regulating materials.

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 with 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.

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. Infused with charcoal, it also naturally reduces moisture and odors.

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.

This foam is often used as part of our base support top layer to seal in our Individually Pocketed Spring system in our Hybrid lines. This foam is ﬂexible and durable, allowing for the other more specialized foams above it to shine while it supports from below.

Flex Support Base 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.

Unbox: Open box and carefully pull out rolled mattress

Unroll: Carefully cut open protective bag to remove and unroll mattress - take care to not use a knife on the protective bag

Expand: Place mattress on bed frame or foundation to let it expand for 24 to 48 hours

Sweet Dreams: Enjoy a restful night's sleep
