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.

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.

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. lt is a more breathable version of our Flex Comfort Foam with liquid cooling gel swirled into the foam's cellular-like structure. This allows it to keep the sleeper cooler and more air circulate through the foam layersaround it.

Egg Crate Flex Comfort Foam

This foam is often used as part of our base support top layer to seal in our lndividually 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

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 toprovide long-lasting durability and support of the top layers.

This is not my first memory foam mattress but it is by far the best I have slept on. My old memory foam mattress was like quicksand when it was new, I would sink in and have a hard time rolling over and the mattress was slow to resume its normal shape. But this one is totally awesome!

Easy to unwrap

It’s much easier if you unwrap it in whichever room it’s going to end up in. It’s really satisfying to watch it expand and didn’t take long though they advise you to wait 24 to 72 hours I felt that mine was fine to sleep on after it had been left overnight.
