Frequently asked questions

Does The One memory foam mattress sleep hot?

All of our mattresses are specifically designed to sleep cool. We run thermal imaging tests and sweat tests to make sure our mattresses feel nice and breezy throughout the night to keep you comfortable.

If you are a hot sleeper, Snow Technology is our most advanced solution to nighttime overheating. The combination of HeatDelete™ Bands, Phase Change Material, and cooling Snow Cover keep you comfortably cool from the moment you crawl into bed.

Which is the firmest mattress in the collection?

The “One” is the firmest mattress in our collection. It is an all-foam mattress made with Breath Flex Foam, Align Memory Foam, and a Casper Core.

What is a mattress in a box? How long does it take for a Casper mattress to expand?

A mattress in a box is a mattress that’s compressed in an air-sealed bag and rolled tight so that it can fit into a box that’s easier to maneuver than a traditional mattress. Allowing you the flexibility and convenience of picking your mattress online and having it easily delivered to your door.

When you receive the mattress, all you’ll need to do is pull it out of its packaging, lay it flat on your bed frame or floor, and let it expand.

Foam and hybrid mattresses can be slept on almost right away but may take up to 48 hours to expand fully. Our Snow mattresses are primarily made with memory foam and can take up to 72 hours to expand fully.
