Mattress Protectors: What To Know Before You Buy

We all know that mattresses don’t come cheap, so it makes sense to do all you can to properly maintain and care for them. Mattress protectors to the rescue!

But with all the choices out there, how do you know which mattress protector is right for you?

To help sort this out, we spoke with fabric expert Jennifer Porter, a designer and sewn goods manufacturer at Satsuma Designs LLC. She shared her expertise and some insider tips about mattress protectors.

From what they are, why they’re important, what features to look for and how to care for them, here’s what to know about the must-have mattress protector.

What Is a Mattress Protector?

Often confused with a mattress pad or topper, which add a thick, soft layer of material for cushioning, a mattress protector (AKA mattress cover) prevents stains, odors, bacteria and microbes from damaging the mattress. It provides a barrier to liquid, leaks, sweat, dirt and allergens.

On top of that, a good quality mattress cover can offer cooling comfort and breathability, as well as prolong the life of the mattress. No wonder it’s considered an essential bedding accessory.

Why Buy a Mattress Protector?

• A mattress protector allows you to sleep easy knowing if your child wets the bed, something is there to absorb the moisture and prevent it from damaging the mattress.
• Some protectors are made of moisture-wicking material that keep you more comfortable if you sweat during the night.
• A mattress protector is easy to clean. A mattress is not.
• A majority of mattress warranties only cover manufacturer’s defects and not improper use, normal wear and tear, liquid stains or spills, all of which void the warranty. For this reason, most mattress brands encourage purchasing a mattress protector to prevent such damage.

Types of Mattress Protectors

• Fitted sheet style: Slides on snugly to cover the top and sides of the mattress. It’s less likely to move around or bunch up.
• Elastic bands: This lies atop the mattress, held firmly in place by stretch elastic straps on all four corners. The sides are not covered.
• Encased/zippered: Provides complete coverage to block dust mites, bed bugs and allergens from getting into your mattress.
• Cooling: Often made from superconductive materials or gel that draws heat and moisture away from the body. They’re excellent at regulating temperature.
• Crib/toddler: Sized specifically to fit child-size beds, they’re usually lined with a waterproof material for obvious reasons.

Mattress Protector Features

Mattress protectors come with different characteristics. When choosing, consider you and your family’s needs. Here are some of the most common mattress cover features.

Fabric

Choose protectors made from 100 percent cotton (breathable), bamboo (sustainable), wool (insulating) or polyester (affordable).

If you prefer organic materials, look for a Global Organic Textiles Standard (GOTS) certified designation. “Shoppers should consider opting for a natural fabric as well as a low chemical load water barrier such as a GOTS-certified polyurethane barrier,” Porter says.

This Saatva mattress protector is GOTS-certified. It’s made of 100 percent breathable organic cotton, which safeguards mattresses while wicking away moisture.

Size and Depth

In addition to knowing the mattress size (twin, full, queen, king), it’s important to consider its depth. “Use a tape measure or ruler to measure your mattress’s depth to ensure a good fit,” says Porter. Most mattress protectors are designed for standard-thickness mattresses, but thicker mattresses or those with toppers require deeper pockets, which not all protectors offer.

If you have a thicker mattress or want to accommodate a mattress topper, look for deep-pocket mattress covers made specifically for this purpose—like this natural option from Avocado or the many choices available on Amazon.

Durability and Maintenance

Many mattress protectors are machine washable, making them easy to clean and maintain. However, to ensure they last as long as possible, it is important to follow the care instructions on the cover’s tag. This typically involves washing on gentle cycles and air drying. Ignoring these instructions could cause the protector to wear out prematurely, leading to an earlier-than-expected replacement.

Allergy Protection and Antibacterial Properties

Organic fabrics like eucalyptus-based Tencel are naturally antibacterial and hypoallergenic. Quilted or fleece-lined covers add extra thickness, while organic cotton is naturally moisture-wicking. Encasement-style protectors cover the mattress like a bag and provide the highest protection against allergens and bed bugs—making them a favorite among allergy sufferers.

Moisture-Repelling Properties

A waterproof cover is essential for children or those who sweat excessively. It is laminated on the mattress side with a water-resistant or waterproof membrane, which prevents liquids from soaking through. While these covers excel at repelling moisture, the membrane can often be crinkly, which might disturb sleep, especially for those who move around a lot at night. Fabric alternatives like cotton or Tencel are quieter but may not provide the same level of moisture protection.

Cost

Considering the cost of mattresses, a quality mattress cover is a smart way to protect your investment. Prices range from as low as $30 to as much as $300. Investing in a premium protector makes sense if you’ve just bought a high-end memory foam mattress. However, a reasonably priced protector should do the job if you’re using a hand-me-down mattress.

How To Clean a Mattress Protector

Most mattress protectors are machine washable, but it’s essential to check the care instructions before buying and follow them closely. “Machine wash a mattress protector on warm or hot, according to care instructions, before the first use and launder each month after that,” Porter says. “In summer and springtime, dry mattress covers on a clothesline outdoors for a beautiful natural result.”

How Long Should a Mattress Protector Last?

According to Porter, a well-made, well-cared-for mattress protector should last two to three years.

Another way to get the most out of your mattress protector? Rotate it 180 degrees after each laundering, Porter says, so the top becomes the bottom and vice versa. This keeps areas from wearing out or fraying too soon.

DIY Tip: “Repurpose old mattress protectors by cutting and sewing covers into pillow inserts, pet beds and more,” Porter says.

FAQ

What is the difference between a mattress cover and a mattress protector?

The terms are often used interchangeably, so it’s hard to pinpoint a clear difference. However, some brands use “mattress protectors” specifically for fully waterproof covers, which provide more protection than generic “mattress covers.”

What are the disadvantages of mattress protectors?

While mattress protectors offer many benefits, including extending your mattress’s lifespan, some users report that they can make the bed warmer, which is a drawback for hot sleepers.

Do you put a fitted sheet over a mattress protector?

Yes. Once your mattress protector is in place, you can make your bed as usual with a fitted sheet, top sheet, comforter and any other bedding you prefer.
