The Brain Sleep Mattress Protector All Seasons brings intelligent temperature control directly to your bed. Designed to cushion your body against sudden shifts in room temperature, it keeps your sleeping environment steady and comfortable throughout the night.
Brain Sleep is a Japanese brand focused on modern sleep science and optimal rest. This mattress protector uses temperature-regulating Outlast technology to actively manage heat. In tests where room temperature swung between 10 and 40 degrees Celsius, Outlast material held the temperature variance to just 4 degrees. Standard cotton, tested under the same extreme conditions, allowed swings of more than 15 degrees.
That means steady performance year-round, whatever the weather is doing outside. If you want to upgrade your bed with thoughtful Japanese sleep design, this protector gives you a reliable foundation for better rest.
BRAIN SLEEP Mattress Protector All Seasons features excellent temperature regulation, helping it adapt to extreme temperature changes. In testing with room temperatures changed between 10°C and 40°C, Outlast material showed a maximum temperature difference of only 4°C, compared with more than 15°C for cotton.
