Advanced Cooling, Pressure Relief and More Sustainable Comfort

The WellFlex ICE Memory Foam Mattress is designed for sleepers who want cooling comfort, body-contouring pressure relief and thoughtfully selected materials. Building on the gel-infused memory foam layers of the original WellFlex, WellFlex ICE adds two inches of foam for enhanced cushioning and cooling performance.

Gel AeroFusion® Memory Foam with ActiveTemp™ PCM helps absorb and regulate excess heat while adapting to the body for comfortable pressure relief. A cooling fabric cover made with organic and recycled materials adds breathability while supporting a more sustainability-focused sleep experience.

The International Chiropractors Association endorsed MLILY’s mattresses and pillows in 2022 following evaluation by its review board.

For sleepers searching for a cooling memory foam mattress, a gel mattress for hot sleepers or a comfortable mattress made with more sustainable materials, WellFlex ICE delivers a cooler and more restorative night’s sleep.

Enhanced Cooling Knit Fabric Cover
This cover breathes, and the airflow creates a cooling sensation that keeps you comfortable while you sleep. This highly advanced fabric has PCM coated threads that has temperature-regulating properties that move heat away from the body. This material is exclusive to our ICE mattresses.

1.5" Gel AeroFusion® Memory Foam/ ActiveTemp™ PCM
PCM stands for Phase Changing Material, meaning it can release or absorb body heat to regulate passive temperature while you sleep. Since body temperature lowers to induce sleep and rises to wake you up, this added coating to our specialty foams helps promote a deeper sleep without interruption.

We have reengineered our proprietary AeroFusion® Memory Foam to incorporate at least 30% bio-based carbon, making it a more sustainable and eco-friendly choice while maintaining its exceptional cooling and temperature-regulating capabilities.

2"Performance Memory Foam
This foam is all about versatility. It mixes 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 fully support the more breathable foams above it.

9.5" Flex Support Base Foam
Flex Support Base Foam is often the bottom layer of our mattresses. A mattress must provide the necessary support 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 for the top layers.
