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.

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.

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.

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.

WellFlex ICE 14-Inch Cooling Memory Foam Mattress

The WellFlex ICE 14-inch mattress is built for sleepers who want the contouring comfort of memory foam without the heat. It starts with everything in the WellFlex, then adds 2 more inches of cooling foams, an Enhanced Cooling Knit Fabric Cover, and a layer of Gel AeroFusion® Memory Foam with ActiveTemp™ phase change material for advanced temperature regulation.

If you are searching for a cooling memory foam mattress, a mattress for hot sleepers, or a memory foam mattress that sleeps cooler, WellFlex ICE combines pressure relief with active temperature control. ActiveTemp™ PCM absorbs excess heat as you warm up and releases it as you cool down, helping keep the sleep surface in a comfortable range through the night.

Beneath the cooling layers, breathable BioBreeze™ Memory Foam, made with at least 30% bio-based carbon, promotes airflow and gently contours to your body. A Flex Support Base Foam core keeps your spine supported, and a fiberglass-free FR inner cover completes the build.

Key Features

  • Enhanced Cooling Knit Fabric Cover that feels cool to the touch
  • Gel AeroFusion® Memory Foam with ActiveTemp™ PCM for active temperature regulation
  • Breathable BioBreeze™ Memory Foam made with at least 30% bio-based carbon
  • 2 more inches of cooling foams than the standard WellFlex
  • Fiberglass-free FR inner cover
  • Available in Firmer 1.0 and Plusher 3.0 comfort levels

Firmness Options

1.0 Firmer: Structured support with minimal sink, built on a 9.5-inch Flex Support Base Foam. Ideal for back and stomach sleepers who run hot.

3.0 Plusher: Deeper contouring and pressure relief with a thicker BioBreeze™ layer and Liquid Gel CoolFlex™ Foam for extra cooling. Ideal for side sleepers who run hot.

Frequently Asked Questions

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.
