The Atlas Mattress was carefully designed to provide optimal comfort and ergonomic support, and is manufactured with the same rigorous attention to quality and craftsmanship that all Casper mattresses are known for.

We've streamlined the best features of our most popular hybrid mattresses, including our Casper Signature Foam and hundreds of individually pocketed flex coils, to keep you cool, comfortable and supported through the night.

The Atlas Mattress was designed to remain comfortable for at least 10 year when used with an appropriate foundation. A 10-year limited warranty guarantees our high-quality materials and superior craftsmanship will last, so you can rest easy knowing your best night's sleep is here to stay for years to come.

The Atlas Mattress is crafted from high-quality materials that will ensure your best night's sleep for at least 10 years.

The top half of the breathable Cozy Knit cover is 99% Polyester, 1% Spandex. The bottom half of the cover is 100% Polypropylene.

Each layer of The Atlas Mattress is made from 100% CertiPUR-US® certified polyurethane foam, with the exception of the Flex Coils, which are 100% steel.

The foam in The Atlas Mattress is CertiPUR-US® certified to ensure any member of your household can sleep safely on your new mattress. It exceeds all Canadian health and safety standards.

CertiPUR-US® approved foams are made without ozone depleters, PBDE flame retardants, mercury, lead, and other heavy metals, formaldehyde, and phthalates regulated by the Consumer Product Safety Commission. They are Low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million).

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.

The Atlas Mattress features a 6" layer of individually pocketed steel Flex Coils that enhance breathability, and move body heat away from the top layers of the mattress for a cool sleep from the moment you lay down until the moment you wake up.
