The One

Every Casper mattress is engineered for both comfort and durability, our premium foams (and innerspring coils inside our Hybrid mattresses) provide lasting support for a full decade—our warranty backs it up.

Do not remove the mattress cover to clean it or the mattress or for any other reason. If you need to clean your Casper mattress or cover, we suggest spot-cleaning affected areas with water and mild detergent. Be careful not to saturate the mattress with too much water and/or detergent, as the foam in the mattress core will soak up water and detergent. Allow the treated area to air dry completely before putting your sheets and bedding back on.

For an easier method of keeping your mattress clean, we recommend the use of a stain and water-resistant mattress protector, which may be removed and cleaned as needed.

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.

Casper mattresses are designed to work on a firm, solid surface like our foundation, platform, or adjustable bed frame. Having the correct support ensures the performance and longevity of memory foam/hybrid mattresses.

For slatted frames, we recommend using bed slats that are flat (not bowed), wooden, and no more than 4 inches apart.

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.

If your old mattress is on the way out but you're not sure what to do with it, we've got some ideas! Did you know that your old mattress can be recycled? Before disposing of your mattress, look into your state's policies for mattress removal, as that will be the most environmentally friendly option. If you are not able to recycle it, consider donating your mattress and any accessories like a mattress topper or box spring to a local charitable organization so that your mattress can go to someone in need. Other options include reselling it, repurposing it, or throwing it away responsibly.
