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.

2

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.

3

1"BioBreeze™ Memory Foam

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.

4

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.

5

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.

6

Fiberglass-free FR Inner Cover

A safe and effective flame-retardant layer around the mattress without the disadvantages of fiberglass and other fire-retardant chemicals.

5

2" Flex Comfort Foam / Egg Crate Top

This embossed foam is an egg-crate pattern that can be added to any foam. The embossed pattern provides additional plushness to the layers above. The undulations in the foam offer constant support and promote airflow to lower the temperature of the surrounding foams.

Frequently asked questions

Who is WellFlex ICE best for?

Hot sleepers who prefer the contouring feel of memory foam, and couples who want very little motion transfer.

Who might prefer a different MLILY mattress?

If you want the bounce and edge support of coils with similar cooling, look at Midnight ICE. If you want firmer zoned support for your back, see ChiroPro.

Does WellFlex ICE transfer motion?

Very little. Its all-foam construction absorbs movement, so a partner getting in or out of bed is barely felt.

Does WellFlex ICE come in Split Head King?

Yes. The Split Head King lets each side of a king raise its head independently on an adjustable base.

Is WellFlex ICE good for hot sleepers?

Yes. WellFlex ICE is the cooling version of WellFlex, designed for sleepers who run hot. It pairs an Enhanced Cooling Knit Fabric Cover with ActiveTemp phase change material and breathable BioBreeze Memory Foam to pull heat away from the surface and help regulate temperature.

What is ActiveTemp PCM?

ActiveTemp is a phase change material infused into the top Gel AeroFusion Memory Foam layer. It absorbs heat when your body warms and releases it as you cool, helping keep the sleep surface at a more consistent temperature.

What is the difference between WellFlex and WellFlex ICE?

The standard WellFlex is a 12-inch memory foam mattress. WellFlex ICE is 14 inches and adds 2 inches of cooling foams, an Enhanced Cooling Knit Fabric Cover, and ActiveTemp phase change material for enhanced temperature regulation.

Which WellFlex ICE firmness should I choose?

Choose 1.0 Firmer if you sleep on your back or stomach and want minimal sink. Choose 3.0 Plusher if you sleep on your side and want more pressure relief at the shoulders and hips.

Does it work with an adjustable base?

Yes. It's designed to flex with an adjustable base, and MLILY recommends a platform bed or an MLILY adjustable base for the best performance.

Is there a weight limit?

MLILY mattresses support about 700 lbs total. For the longest life, use a solid platform foundation or an MLILY adjustable base.

Is there a sleep trial?

MLILY doesn't offer an in-home sleep trial. Items bought on mlilyusa.com can be returned within 30 days if they're unused and unopened in the original packaging. The best way to test the feel first is to lie on it at an MLILY retailer near you.

What warranty does it come with?

Every MLILY mattress is backed by the MLILY 10-Year Warranty, which covers defects in materials and workmanship. You get the same warranty whether you buy online or from an authorized retailer. See warranty details.
