    The only mattress protector I will buy!

    I have purchased this for two mattresses already and it is truly the best one on the market. It is waterproof but doesn't make that crunching sound while you sleep. 10/10.

    Protection without sacrificing comfort

    Fits great. I also can't tell it's there. This mattress is for our three year old so it's great to get protection without sacrificing comfort.

    Secret Performer

    For this protection, we don't even know it's there. The installer recommended only using this protector and forgoing a mattress pad to allow for good mattress breathing.

Frequently Asked Questions

The best mattress protectors match utility with comfort. You don’t want anything that squeaks or smells, but you need a quality mattress protector that actually protects you and your bedding.

To meet these standards, a waterproof mattress cover should use a material that’s liquid-proof and breathable—like Casper’s thermoplastic sheeting.

Additionally, full and fitted coverage is crucial. Unlike a waterproof mattress topper, covers need to guard all exposed surfaces (top, sides, and at least partial bottom). We use a clinging stretch design that never slides or shifts, providing maximum waterproof protection.

Yes—at least quality ones like Casper’s do.

 A waterproof protector guards your mattress pad and mattress by providing a physical waterproof barrier against potential risks. With a removable twin, full, queen, or king mattress protector, you can wash away dirt, stains, and dust mite infestation before they reach your entire mattress.

On average, a waterproof mattress protector lasts one to two years. However, a quality mattress protector like ours can last longer (just make sure to check for signs of wear).

As a rule of thumb, wash your waterproof protector every few months to prevent dirt or germ buildup. But if you have an unfortunate spill or accident, feel free to wash right away. For best results, we recommend you hand wash and air dry. It might be tempting to wash and dry on hot, but heat drying could cause delamination and shrinkage.

For bed owners, it’s better to be safe than sorry—and a waterproof bed protector is one way to stay safe.

 Dirt, sweat, stains, and other unwelcome elements can easily ruin mattress quality. Using a waterproof cover not only prevents you from having to buy a new mattress but also saves you from stressing over every manner of liquid that could accidentally end up in your bed.

Some might, but Casper’s is designed not to.

 If a waterproof mattress protector doesn’t provide an outlet for body heat, that moisture will condense and create sleep-ruining sweat. Casper’s mattress protector has microscopic pores, allowing warm air to circulate out, rather than get trapped in.

If new to shopping for mattress protectors, look for some key functional features:

  •  Full-coverage fitted design – This allows you to easily slip off the protector for cleaning, while still covering all exposed surfaces.
  • Effective waterproofing – A mattress protector should be impenetrable to most stains.
  • Silent, comfortable fabric – A good cover won’t interfere with your rest by squeaking when you move or altering the feel of your mattress.
  • Breathability – Your mattress cover should prevent sweat stains, not cause them. Look for breathable designs to maximize airflow, leaving you to enjoy a cooler night’s rest.
