The waterproof mattress protector keeps any mattress looking and feeling brand new by guarding against dirt, spills, and normal wear and tear.

Casper was created to re-imagine sleep from the ground up, beginning with its obsessively engineered, outrageously comfortable mattress. All of Casper’s sleep products are developed in-house by the company’s award-winning R&D team, including its airy sheets, pillow-in-a-pillow, and inventive Lounger and Layer designed exclusively for Target.

Casper was recently named one of Fast Company's Most Innovative Companies in the World and its eponymous mattress was crowned one of TIME Magazine's Best Inventions.


What’s the difference between a mattress protector and a mattress pad?
Purchasing a protector means you have the intention of preserving your investment by ensuring it won't be damaged. This is different than a pad, which is generally used to add cushioning.

Will your mattress protector make the mattress sleep hotter?
The Casper mattress sleeps cool, and the protector is designed to do the same. The knit fabric features has an integrated spacer layer, so air flows through it easily to keep things nice and breezy.

How do I care for my mattress protector?
For best results, machine wash on warm and tumble dry low. Heat drying could cause delamination and shrinkage. Avoid dry cleaning.

What is the 100-Night Trial?
We believe you should actually sleep on a product to decide if you like it. So we give you 100 nights to test out all Casper products in your own home. If you don’t love it, we’ll give you a full refund.

Goes on like a regular fitted sheet, which is a plus. Much easier than the ones with zippers. Made with a quality material that feels soft and doesn't make any weird rustling noises when you lay down on it.

When I purchased the complete set of Casper mattress products (including a duvet and two sets of sheets!), somehow the mattress pad was left out. For a few months, I used a waterproof mattress pad I already had which was adequate but just not right. While buying other items from Target, I finally ...see moreof the reviewer's review

This cover is super nice, soft and cottony. The waterproof layer is made of material used in outdoor apparel, which means it's either Gortex, Neoshell or eVent, most likely. In any event it is made to be washed and dried on low with no harm to the waterproof protection, same as outdoor gear. Mine wa...see moreof the reviewer's review

We previously had a zipper mattress cover that covered our whole mattress, and it kept our sheets from staying on the mattress they’d get all bunched up while we slept. Two years into this madness I decided that maybe it’s the cover - low and behold we purchased this beauty for our King and I have s...see moreof the reviewer's review

I love sleeping on the mattress and the mattress cover. It washes nicely also and is very protective. I would definitely recommend it to my family and friends. In fact my son recommended Casper for me because his whole family sleeps on Caspers and all have the protective cover as well. Thanks for...see moreof the reviewer's review

I’m not happy with the matress protector. It seems too big so it wrinkles and I end up sleeping on big folds. I would prefer more cushioning. I had to buy another matress cover with more quilting.see moreof the reviewer's review

Not Loving It

Suzanne Pacetti 12 days ago
The mattress protector makes our sheets ripple and bunch unlike any other mattress protector we've ever had. We have high quality sheets, so they are not the issue. Will probably purchase another mattress protector elsewhere since it's annoying to have the "corduroy effect" when we sleep.see moreof the reviewer's review
