Glove Service is an option for specific MLILY products that includes delivery and setup with your purchase. If purchasing a White Glove qualifying product, our team will ship your order to a delivery provider near you.

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. 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 Flex Comfort Foam
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
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
