Casper Mattress Topper

The topper is designed to balance plush comfort with responsive support. While it adds a three-inch layer of cushioning, the multi-layer construction is engineered to prevent that 'sinking' feeling often associated with pure memory foam.

Yes, the top layer features perforations designed to actively promote airflow. This helps dissipate body heat that would otherwise get trapped in the foam, keeping the surface temperature more neutral throughout the night.

No, only the quilted knit cover is machine washable. The foam layers should be spot cleaned only and kept away from direct heat or harsh chemicals.

The topper is designed to sit securely on your mattress, but it does not feature straps. Most users find that the weight of the foam and the friction of the knit cover keep it in place once your fitted sheet is applied over it.

It adds a three-inch layer of contouring memory foam to your sleep surface. If your current mattress is very firm, this will significantly soften the feel; if your mattress is already quite soft, it will add a layer of plush, pressure-relieving comfort.

Casper offers a 5-year limited warranty on this topper. This covers manufacturing defects, such as significant indentations or splitting in the foam, under normal household use.
