Mattresses get damp from time to time, whether it’s from urine, sweat, baby bottles that leak, or bedtime beverages. The best way to keep them dry is to invest in a waterproof mattress protector. This mattress cover can be removed and washed as needed, keeping your mattress fresh, clean, and dry.
Before you start shopping for your waterproof mattress protector, there are a few decisions you have to make first. Do you want a waterproof mattress protector that is also hypoallergenic?

What to Consider When Choosing the Best Waterproof Mattress Protector
Before you start shopping, decide how much of your mattress you want to be waterproof. There are a few different kinds of waterproof mattress protectors, and the item’s packaging should indicate just how much of the mattress it protects. There are three common types of waterproof mattress protectors: top, five-side, and encasements.
- With top protectors, the most common type, the top of the mattress is the only part that’s truly guarded against water and other liquids.
- Five-side protectors are the next step up in keeping your mattress safe from spills and sweat. These cover the mattress top and all four of its sides. Both top protectors and five-side protectors fit on a mattress in much the same way as a mattress pad or a fitted sheet.
- Encasements zip all the way around to protect the whole mattress—covering the top, bottom, and all four sides—making them ideal for keeping various allergens and bedbugs, as well as liquids, away from your sleeping surface. The only real downside to encasements is that it takes some effort to get one on a mattress; you’ll have to lift the mattress off the frame to encase it.
To determine the best waterproof mattress protectors for the beds in your home, first, think about how much protection each member of your family needs.
Material & Fabrics
When you’re ready to shop for a waterproof mattress protector, try to find a vinyl-free model. Those made without vinyl are more breathable and don’t rustle loudly when you turn over in bed. Many of the better waterproof mattress protectors on the market are also hypoallergenic, with some even keeping bedbugs and dust mites away from your mattress.
The best mattress protectors are made of organic cotton or wool, and there are also quality protectors made from rayon, bamboo, and polyester. If you think you’ll have to launder it frequently, make sure it’s well made and machine washable.
Size & Fit
In the U.S., mattress sizes are standard, so you’ll have an easy starting point when measuring for your mattress protector. Be sure to carefully measure the depth of your mattress (or the “pocket”) to find the right size mattress protector.
When picking your mattress protector, make sure it’s large enough to cover your whole mattress. If it’s not large enough, you’ll find yourself making and remaking your bed often, as the mattress protector will fit too tightly and won’t grasp the corners well enough to stay tucked in over time. Likewise, remember to read the protector’s laundering instructions before throwing it in the washing machine. You don’t want to use the wrong wash setting and turn your queen mattress cover into a twin-size one when the laundry is done.
