For best results, we recommend you machine wash on cold and tumble dry low. It will be tempting to wash and dry on hot — resist this urge! Heat drying could cause delamination and shrinkage. We want your protector to last as long as possible. You may also opt to air dry. We do not recommend dry cleaning the protector. Do not use solvents, bleach, or fabric softener.

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.
