🧊 The Science of Cooler Sleep — Inside IceFlex™ Technology
Most mattresses promise “cooling.” IceFlex™ delivers science-backed, sustained temperature control that keeps you balanced, refreshed, and deeply asleep — all night long.
When Sleep Gets Too Hot to Handle
You know the feeling — waking up warm, kicking off the covers, flipping your pillow. Overheating is one of the biggest barriers to quality sleep. As body temperature rises, heart rate increases and sleep stages are disrupted, pulling you out of restorative rest.
The Black Diamond Hybrid Mattress solves this at the source — not with a temporary “cool-touch” trick, but with a system that regulates your micro-climate from the inside out. At the heart of that design is IceFlex™ Cooling Technology.
What Is IceFlex™ Cooling Technology?
IceFlex™ is a mineral-infused innovation integrated into strategic layers of the Black Diamond Hybrid Mattress. Cooling bands actively draw excess heat away from your body and disperse it through breathable layers beneath the surface.
Instead of relying on a surface that feels cool for an hour, IceFlex™ works continuously, balancing your sleep climate for up to 12+ hours of consistent temperature regulation.
Engineered to help keep you up to 2°F cooler — no fans, no gimmicks, just mineral science that supports nightly recovery.
Why Temperature Matters for Deep Sleep
Your body naturally cools as it transitions into sleep. If bedding traps heat, your system works harder to maintain rhythm — leading to restlessness, sweating, and wake-ups. Cooling tech like IceFlex™ supports natural thermoregulation so you can move smoothly through all sleep stages.

Inside the IceFlex™ System
The IceFlex™ design is more than a single layer — it’s a balanced ecosystem:
- CoolTouch™ Ultra Cover — Breathable, moisture-wicking fabric that feels fresh against your skin.
- IceFlex™ Cooling Bands — Mineral-infused strips between comfort layers pull heat downward and away from your body.
- Cool Titanium Memory Foam — Responsive contouring without trapping warmth.
- 9-Series Wrapped Coils — Promotes airflow and isolates motion for cool, consistent support.

IceFlex™ vs. Traditional “Cooling” Foams
Many gel or “cooling” foams provide short-term relief — once saturated with body heat, their effect drops off. IceFlex™ differs in composition and placement so it keeps performing night after night without relying on a fleeting surface feel.
Cooling Meets Comfort: The Perfect Balance
Cooling alone isn’t enough — true rest requires comfort and support. Black Diamond combines IceFlex™ with precision layering to relieve pressure and align your spine. It’s ideal for hot sleepers, couples, and anyone seeking luxury-level recovery at home.
For full adjustability and circulation benefits, pair it with the BedTech BT3000 Adjustable Base for personalized elevation and Zero-Gravity comfort.
