Well constructed; has a comfortable

"Well constructed; has a comfortable feel with the right level of support; and didnt’t have much of a smell. However, it keeps my son too warm. It may be an advantage for winter nights perhaps - TBD - but during August & September, my son sweated a lot more than usual compared to lying on a mattress without a topper."

Q&A

Frequently asked questions

Is the Casper mattress topper washable?

The memory foam mattress topper is not washable, and we do not recommend removing the quilted knit cover. Instead, spot clean with mild detergent and air dry away from direct sunlight or heat.

Will the mattress topper help if I’m a hot sleeper?

Yes! Our mattress topper is designed with breathable, open-cell foam, which pushes heat away and keeps air circulating, making it perfect for hot sleepers who want to stay cool throughout the night

Can this topper improve the comfort of my current mattress?

Absolutely! Our mattress topper combines a responsive top layer with cradling memory foam to add extra softness and support, transforming your current mattress into a more comfortable dreamscape.

Can I get another copy of the assembly instructions?

Absolutely! Click here to download a PDF of the Mattress Topper assembly instructions.
