FAQs

Love your bed, but not all the heat buildup? Although they can reduce pressure points, beds with memory foam often get uncomfortably hot. Slumber Cloud bedding with Outlast® technology helps prevent the heat from your mattress from building up. You'll still enjoy the comfort of your mattress but without that hot, sweaty feeling.

Although each of these products utilize Outlast® technology to help you sleep at the perfect temperature, each product addresses different needs. If you need the most temperature-regulation performance, one of our mattress pad options are right for you. If you need 100% waterproof protection and temperature-regulation, you should choose the mattress protector.

Definitely! When you sleep hot but your partner sleeps cold we refer to this as being “thermally incompatible”. Our bedding is designed to automatically adjust to each sleeper’s ideal sleep temperature. With the unique ability to react to each sleeper's temperature independently, our bedding ensures that both you and your partner will sleep comfortably all night long.

Although both mattress pads utilize Outlast® temperature regulation technology - the Performance Mattress Pad also incorporates a layer of moisture wicking fabric for dual technologies.

The Core Mattress Pad will solve most sleepers temperature issues, but for those that need the most temperature control, they should choose the Performance Mattress Pad.
