Graphene-enhanced Cooling Knit Fabric Quilted Cover

This cover is very similar to our cooling knit fabric cover except that is has added quilted layers infused with Graphene. It enhances heat regulation and antibacterial capacity, creating a cool and hygienic sleeping experience. Additionally, it aligns your spine and molds to your body’s natural contours for a more comfortable feel.

Copper Gel AeroFusion™ Memory Foam

The compressed copper and gel particles are infused into the AeroFusion Memory Foam®, forming a soft and antimicrobial film close to the human skin. It can regulate moisture and reduce odor, thus reducing the risk of skin diseases and ensuring a clean and comfortable sleep environment.

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.

Pocketed Spring With Foam Encasement

We manufacture our own springs to ensure that the quality matches the foam that surrounds them. The specially crafted pocketed coil system enables the mattresses to be rolled and compressed for convenient shipping. Moreover, our pocketed coils are unparalleled in their ability to provide support and adaptability, allowing the sleeper to relax and rejuvenate.

Flex Support 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

Unroll

Sweet Dreams!

Enjoy a restful night's sleep.
