    Comfy, you don’t even know it is there!

    So far so good! We are on our second Casper mattress and always buy the protector cover from Casper. You don’t even know it is on there and it is so comfortable!

    Comfortable breathable high quality

    The mattress protector is comfortable and breathable. It does not have a plastic feel. It's soft. We have a dog who likes to throw up on the bed and it has so far held up quite well to resist stains.

Frequently Asked Questions

Typically, a mattress protector helps prevent everything from liquid, stains, dirt, and dust from causing permanent damage to your mattress. It can even provide an extra layer of protection to deter bed bugs from getting to your mattress.

A cooling mattress protector does all the above and keeps you cool. Breathable designs and heat-resistant materials keep you and your bed safe, cool, and sweat-free.

The best mattress covers will protect your mattress without impacting the comfort of your mattress. Quality cooling covers (like Casper’s) also allow for breathability.


To pick the best cooling mattress protector for a hot sleeper, prioritize these cooling protector qualities:


  • High airflow or breathability – Look for cooling properties with microscopic pores, allowing air to circulate for cooler sleep.
  • Water-resistance – Stop sweat, water, or the occasional glass of wine from ruining your mattress pad or actual mattress.
  • Noise-free – Avoid sleep-disturbing squeaks in the night with a mattress cover that’s free of crinkling material.
  • Full coverage – For effective protection, you need to cover any and all exposed mattress sleep surface—top, sides, and partially the bottom. Zippered or form-fitting mattress cover designs are best for full coverage.

Absolutely—if they have the right design and material.

Our spacer knit design allows air to move between you and your mattress, which is the primary problem with run-of-the-mill mattress protectors. Certain materials (like the polyester in our protector) also resist excess heat retention.

It certainly can, and that's exactly what we've designed. Our breathable cool mattress protector combines fabrics with specific woven designs to keep you cool and enhance breathability.

Sweat-inducing mattress protectors are usually a result of poor material choice.

When made with low-porosity fabric, mattress protectors end up trapping heat—often resulting in night sweat. To escape this discomfort, avoid heat-retaining materials, like vinyl, heavy synthetics, or certain dense memory foams.

Not ours! We believe mattress protection shouldn’t come at the cost of comfort. With its smooth polyester case, Casper’s cool-touch mattress protector ensures a crinkle-free and perfectly chilled experience.

While not absolutely necessary, mattress protectors are essential for providing superior protection against spills, moisture, dust, pet dander, bed bugs, dust mites, and other allergens. They help in maintaining your mattress investment by keeping it looking and feeling brand new, guarding against normal wear and tear, and are highly recommended.

Yes, you typically put a fitted sheet over a mattress protector. The protector acts like a safeguard for your mattress, while the fitted sheet provides an additional layer of comfort. This way, you get to enjoy the benefits of both cooling and waterproof mattress protector features without compromising on comfort.

While a mattress protector offers superior protection against liquid and stains, it’s recommended to sleep on a fitted sheet placed over it. This ensures that you experience the softness and comfort of your bed, while the protector works underneath to shield against spills and moisture.

It’s advisable to wash your mattress protector whenever it gets dirty or at least once every two months. Most protectors, including Casper’s, are machine wash friendly, making it easy to maintain hygiene and protect against dust mites and other allergens.
