This mattress uses a triple-action cooling system that helps keep you comfortable all night. Each layer works together to keep the surface cool and prevent heat from building up while you sleep.
The first layer is the Douglas CoolSense Cover with CryoFusion Cooling Nanofibres. These fibers help pull heat away from your body and keep the top layer feeling cool and fresh.
Below the cover is a layer of Luxury ecoLight Cooling Gel Foam + Polar Temperature Balancing. This layer absorbs heat and spreads it out to avoid hot spots under your body.
The third cooling feature is the breathable design of the mattress. It lets air move freely through the foam, helping carry away heat and moisture as you sleep.
This three-part cooling system works well for people who get hot during the night. It keeps you cool not just at the start, but all through the night.
Many users say they sleep better and no longer wake up sweating. The cooling layers help your body stay at a more comfortable temperature, which helps you fall asleep faster and stay asleep longer.
The cooling materials are also eco-friendly. That means you can enjoy better comfort and make a better choice for the environment at the same time.
