WellFlex 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 Memory Foam

This memory foam is generously infused with a cooling gel. It keeps all of the positive properties of memory foam, like contouring and conforming to the sleeper, while mitigating temperature issues with the gel infusion.

Performance Memory Foam

This foam is all about versatility. It mixes qualities of durability, flexibility, and adaptability into a single memory foam. Performance Memory Foam is often used as a mid-section foam due to its ability to both fully support the more breathable foams above it while allowing them to gently contour to the sleeper.

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

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.

Enjoy a restful night's sleep.
