How it works

Engineered for Heat Zones, Not Just Surface Cool

Real cooling where it counts, and premium construction that lasts.

Most “cooling” toppers only treat the surface and stop working after an hour.

Dosaze embedded ThermaCool Bands exactly where your body generates the most heat, so you stay cool all night, not just at bedtime.

Plus, it’s built with breathable, gel-infused memory foam and a ice-to-touch cover for cooling, comfort, and pressure relief.

6.94°F Cooler, All Night Long

Independent testing proved the ThermaCool™ Mattress Topper can lower surface temperature by up to 6.94°F, even under continuous body heat.

This isn’t a quick burst of cool that fades after bedtime - it’s sustained, targeted thermal control designed to keep you comfortable for hours.

Cool-To-Touch Cover

The ThermaCool™ Topper features a cool-to-touch cover made with advanced Phase Change Material that instantly pulls heat away from your skin.

Unlike standard fabrics that trap warmth, this cover reacts to your body temperature to deliver a cool-to-the-touch sensation that’s both refreshing and breathable all nig

Electricity Free Cooling

No wires. No plugs. Just science.

The ThermaCool™ Mattress Topper uses passive cooling technology powered by ThermaCool Bands and phase-change materials to help keep you cool for up to 12 hours.

No electricity. No noise. Just better sleep.

Perfect Durability Blend

Durable, breathable cooling layer that maintains its structure night after night, delivering consistent cooling, long-lasting comfort, and a premium feel that won’t break down or lose effectiveness over time.

We’ll be honest - the Dosaze ThermaCool Mattress Topper isn’t the cheapest option. But if you’ve ever struggled with overheating, night sweats, or tossing and turning just to find the “cool side” of the bed, you already know how valuable real cooling comfort is. Hot sleepers lose more than just sleep—they wake up groggy, dehydrated, and restless. Over time, those restless nights affect everything: your mood, energy, and focus. ThermaCool’s proprietary heat-dissipating technology is designed to pull excess warmth away from your body and maintain a consistent, breathable sleep surfaceso you stay cool, dry, and deeply asleep all night long. You spend one-third of your life in bed. Why settle for waking up sticky and exhausted? ThermaCool is built to last, with high-quality materials and multi-layered construction that keeps performing night after night even in the hottest months. If cool, uninterrupted sleep matters to you, the ThermaCool Mattress Topper is worth every degree.

Waking up drenched in sweat or tossing all night trying to find the “cool side” of the bed? You’re not alone. Overheating during sleep is one of the most common (and most overlooked) reasons people wake up feeling exhausted instead of refreshed.


Here’s the truth: you’ll spend over 230,000 hours sleeping in your lifetime. And if you’re overheating for even half of those, that’s a serious hit to your comfort, recovery, and overall health.


So let’s be real. You could grab a cheap memory foam topper right now and call it a night. But if it traps heat and turns your bed into a sauna by 2 a.m., what’s the point?


We built the Dosaze ThermaCool Mattress Topper for people who are tired of sleeping hot. Literally.

Technology

The ThermaCool™ Mattress Topper uses a three-part cooling system to regulate your body temperature and keep you comfortable all night:

  1. Ice-to-Touch Cover – Made with advanced Phase Change Material, the cover absorbs and dissipates body heat the moment you lie down, giving you an instant cooling sensation.
  2. Gel-Infused Memory Foam – This breathable layer cradles pressure points while drawing heat away from the body for long-lasting comfort.
  3. Graphite-Infused ThermaCool Bands – Strategically placed under your body’s hottest zones (like the midsection), these bands actively absorb, conduct, and release heat—helping you stay cool all night, not just at bedtime.

Lab-tested to stay up to 6.94°F cooler, ThermaCool is engineered for real, sustained temperature regulation, not just a cool burst that fades after an hour.

Yes, it is. You can see more details on our certification here. It is also OEKO-TEX Standard 100 certified, so you can rest assured that you're sleeping on safe, high-quality materials.
