A mattress protector is just as essential as bed sheets or the duvet. By keeping moisture, sweat, dirt, dead skin cells and other stuff from getting into your mattress, a mattress protector ensures your bed stays clean, hygienic and safe. 

If you are thinking about buying a mattress protector, we’ve written an in-depth buying guide explaining what to look for and the different types of mattress protectors. 

Why You Need a Mattress Protector 

• A waterproof mattress protector keeps liquids from penetrating into the mattress, where they can cause stains, smells, mold and bacteria. This keeps your mattress hygienic and fresh. 
• A mattress protector keeps your mattress clean. This is really important considering you cannot wash your mattress like you do your sheets or duvet. 
• A mattress protector keeps allergens like mold spores, dust mites, pet dander and pollen from settling on your mattress where you’ll be constantly breathing them in. This is particularly important for people with allergies and respiratory problems like asthma. 
• Some mattress protectors are designed to keep bedbugs and other pests out of the mattress. 

5 Features to Consider When Shopping for a Mattress Protector 

1. Waterproof 

Whichever mattress protector you buy, make sure it is waterproof. Even if you are not dealing with an incontinence issue, a waterproof mattress protector is still important in case of spills and other messes.

Note that for most mattress protectors, only the top part is waterproof. The sides where it wraps around the mattress are typically not waterproof or even water resistant. If you want all-around protection, look for a mattress protector that encases your entire mattress and has a waterproof backing on all sides.  

By the way, don't confuse a mattress protector with a mattress cover. Standard mattress covers are not waterproof and provide limited protection to your mattress. 

2. Soft and Silent

The crinkly vinyl mattress protectors we grew up with are no longer in fashion. Today, you can get a mattress protector that’s a lot more comfortable and quiet while still enjoying complete waterproof protection. 

Modern mattress protectors consist of a waterproof backing underneath and a softer material on top, usually polyester, cotton or bamboo. Some mattress protectors also have a thin filling of microfiber to provide some soft padding. 

3. Breathable 

Don't get a mattress protector that traps heat inside your mattress. This is especially important if you already have a heat-trapping memory foam mattress. 

A good mattress protector should be waterproof while still allowing air flow through it. This keeps you cool and reduces night sweats. 

If you are a hot sleeper, look for a mattress protector made from highly breathable materials like cotton and bamboo. They feel cooler than polyester. 

4. Secure Fit

Next, check the type of closure a particular mattress protector uses. The last thing you want is a mattress protector that won’t stay in place. 

Most mattress protectors use an elastic skirt to secure it to the mattress. Make sure the skirt is deep enough to comfortably go under your mattress, especially if you have a thick mattress. 

If you want full mattress protection (useful for bed bug protection), look for an encasement mattress protector with a zip closure.  

5. Easy to Clean 

Finally, get a mattress protector that’s easy to maintain and clean. It should be machine washable so you can easily wash it at home. 

You don't need to wash your mattress protector as often as you do bed sheets. In fact, washing it too often can damage the waterproof backing. 

Wash your mattress protector every 1-2 months. Follow the cleaning and drying instructions to ensure you don't damage it or reduce its lifespan. 

In between cleanings, a quick vacuum now and then will keep the mattress protector clean. If it smells a bit funky, sprinkle baking soda on it, leave it for an hour and then vacuum. This will deodorize the mattress protector. 

If the mattress protector gets a stain, consider spot cleaning instead of washing the entire thing. Use soap and water for mild stains or stain removers for more serious stains. Leave the mattress protector uncovered until it is completely dry.
