FAQ

The lowdown on some commonly asked questions

Our mattress pads are made with NASA-inspired materials that pull heat away from your body. They help you sleep cooler and more comfortably without waking up sweaty.

Yes. Slumber Cloud protectors don’t just feel cool at first. They actively regulate your temperature throughout the night by absorbing and releasing body heat.

Breathable pads allow air to flow, but our cooling pads respond to your body temperature to help prevent overheating before it happens.

Absolutely. Our cooling pads work great with memory foam and help offset the heat-trapping nature of foam mattresses.
