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

It doesn't fit the bed PERFECTLY which is odd since it is from the same company as the mattress although it is fantastic. Makes you feel like you are sleeping right on the Casper mattress.

It doesn’t fit my Casper mattress as well as I would like. It’s large enough that it bunches up during the night and I am left sleeping on folds. I did wash and dry it as directed before putting it on the bed.see moreof the reviewer's review

Let me be the first to say I am a Casper fan boy. I don’t have a Casper mattress yet (still have a fairly new temper-pedic but when that goes. . .) but I do have several sets of sheets, duvet covers, pillows, dog beds, etc and love love love it all. I can’t wait to get the fresh Casper sheets from...see moreof the reviewer's review

I heard such great reviews about it so I bought one. Not impressed! It’s bunching up in the middle so I’ve been having to pull the sides. Not sure how well it takes with spills and accidents but I’d rather not find out.see moreof the reviewer's review

I bought this in the store. It was an online return. That should have been my first clue. It was meant to go over my toddler's twin bed so I figured I'd spend a little more for extra waterproofing protection since sippy cups are likely to end up on the bed eventually. It happened in the first week. ...see moreof the reviewer's review
