FAQs

I sleep hot, my partner sleeps cold. Is this going to work for us?

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.

What's the difference between a mattress pad and a mattress protector?

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.

What firmness is best for me?

Pick your firmness based on your typical sleeping position. The soft-medium pillow offers the perfect support for those that prefer to sleep on their stomach and back. The medium-firm pillow is recommended for those who regularly sleep on their side and back.

How do I layer a mattress pad on my bed?

The technology in our mattress pads is designed to work even when used underneath your fitted sheet. We recommend to layer the mattress pad on top of your mattress but under your fitted sheet. If you are using a mattress protector, layer that first followed by the mattress pad and fitted sheet.

These sheets and duvet cover are so comfy and cozy! They really do keep me cooler at nights too; which I've been fighting with my entire life - I'm an overheater! I already recommended them to my best friend.

Perfect for California Summer! I love the lightweight and how well it regulates heat, so that we are not hot nor cold. It is perfection. I was hesitant because of the cost but glad that I decided to purchase it
