Comfort is essential for a good night’s sleep, but when it comes to bedding – especially pillowcases – there are other factors you should consider as well. Is the material soft enough for sensitive skin? Will it hold up in the washing machine? And will it keep your pillow protected in case of an accident? A waterproof pillow protector can do all of that.
Pillow protectors act as a protective barrier between your pillow and the pillowcase. It keeps moisture from drool, sweat, and spills from reaching the inside of the pillow and prevents allergens like dust from accumulating and aggravating your allergies. A good pillow protector is durably constructed from high-quality materials and provides lasting waterproof protection.
There are plenty of pillow protectors on the market, but if you’re looking for the best waterproof pillow protector you should check Amazon. We’ve read customer reviews and done our own in-depth research to bring you a round-up of the best options on the market.
Do You Need a Waterproof Pillow Protector?
A pillow protector does exactly what the name would suggest: it protects your pillow. If you’re a hot sleeper, a pillow protector can keep night sweat from penetrating the pillow cover into the filling. A damp pillow can become a breeding ground for bacteria, and that’s the last thing you want anywhere close to your face night after night.
Pillow protectors can also be beneficial for people with allergies. Dust can accumulate inside the pillow, contributing to eye, nose, and throat irritation. A pillow protector creates a physical barrier against these allergens as well as your body’s natural oils and shed skin cells. It can also help keep substances like makeup and hair dye from staining the cover of the pillow.
There are plenty of pillow protectors on the market, but do you really need one that is waterproof? Maybe not, but if you’re aiming to protect your pillow you might as well go all-in. A waterproof pillow protector will come in handy if you have a habit of drinking (and spilling) in bed or if you have pets who sometimes mistake your bed for a bathroom.
Shopping Tips for Pillow Protectors
Pillow protectors come in a variety of shapes, sizes, and materials so you can really find the perfect one to suit your needs. But what kind of pillow protector DO you need?
First and foremost, think about what you’re trying to protect your pillow against. Do you have allergies that are aggravated by dust? Are you concerned about bed bugs or bacteria? Do you want to protect against liquid spills? Answering these questions will help you narrow down the options.
Here are several additional factors to consider when shopping:
Size
If you don’t know where to start in shopping for pillow protectors, start with the size. Pillows generally come in three sizes – standard, queen and king – so choose the one that fits the pillow you use most.
Material
Pillow protectors are made from a variety of materials including cotton, polyester, bamboo and even vinyl. If you want the best of the best, consider an organic waterproof pillow protector or one made from other premium materials.
Comfort
Some materials are soft while others are more structured. Consider the feel you’re going for and think about bonus benefits like cooling properties.
Construction
A quality pillow protector will completely encase the pillow and provide an impenetrable barrier. Look for sturdy seams and zippers that won’t wear out.
Maintenance
Though your pillow protector is designed to keep contaminants out, you’ll still want to wash it from time to time. Machine-washable protectors are convenient, just be sure to check the manufacturer’s instructions for drying recommendations.
If you tend to sweat a lot at night, a waterproof pillow protector will certainly come in handy. These covers create an impenetrable barrier against moisture and liquids, keeping mildew and mold from forming on the surface of your pillow and inside it. Not only can mold and mildew negative affect your health, but they can create an unpleasant odor that might impact your sleep quality.
Bottom Line
Whether you’re prone to night sweats or like to enjoy beverages in bed, a waterproof pillow protector can come in handy. The right materials will keep you cool and comfortable while creating an impenetrable barrier to protect your pillow.
