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.

What is Comp. Value?

Our Comparable Value prices reflect the price at which we or third parties have offered this item or a comparable item.

How does Casper create the best value products for their sleepers?

Everything must help sleep and must be tested.

Our team regularly searches the market and tests comparable mattress and sleep products to ensure that ours offer top-quality materials, the most value for your dollar, and the best sleep experience on the market.

Every Casper mattress is designed and assembled in the USA.

As part of the Carpenter Co family, Casper mattresses are manufactured by the largest foam manufacturer in the world—no middle man, no markups, just the best prices for our sleepers.

We don’t rely on gimmicks—just 12+ years of expertise.

With 12+ years in the mattress and bedding industry, the Casper team knows what makes a great night’s rest and what’s just fluff. Our mattresses and bedding are obsessively-engineered and precisely-layered to help you get your deepest sleep ever.

We don’t sleep on getting you the best possible deal.

The Comp. Value shown for Casper products is never set it and forget it. Our team conducts thorough market research every quarter to ensure our comparable value is always accurate to the bedding market and the three most comparable products, so you never have to worry about missing out on savings.
