A waterproof mattress protector prevents liquids and sweat from soaking through the surface of your mattress, helping to prolong its life. These protective covers are especially useful if you have young children who still struggle with bed-wetting or pets that shed, or if you suffer from a chronic medical condition like diabetes or incontinence. There are many options available on the market, but some have different features than others, and the right one can make a big difference in how comfortable your sleep is.
The first step is to determine what your needs are. Do you want a mattress cover that is breathable, or one that adds extra padding to your bed? Do you prefer a soft fabric that feels like cotton or bamboo, or a cooling material such as Tencel? Waterproof protectors are available in all of these varieties, and there are also options for a variety of mattress sizes.
You will also need to decide if you need a waterproof or a water-resistant protector. Waterproof covers are designed to completely halt the flow of liquids, so they're perfect for overnight accidents or situations where you can't get to a spilled drink fast enough. Water-resistant protectors can fend off some liquid for a while, but they'll soak through eventually, particularly if the spill is large or has been left on the mattress for a long time.
Another important consideration is how easy the protector will be to clean and maintain. Some are machine-washable, while others must be hand washed or dry cleaned. Look for a product with care instructions that you can easily follow, and consider investing in a couple of protectors at once if you'll be washing them frequently.
A waterproof protector will keep your mattress hygienic and free of stains, helping to preserve the integrity of your investment and ensuring that your manufacturer's warranty won't be voided by a stain or leak. It will also protect against the build-up of dust mites, which can lead to a runny nose, itchy eyes and shortness of breath.
In addition to protecting against spills, a waterproof mattress cover can help keep your sleeping environment cool and comfortable. Sweat, body oils and other natural moisture can accumulate in your mattress, creating a breeding ground for bacteria and causing unpleasant odors. A waterproof cover can help prevent these substances from seeping through to your skin and clothing, so you can get a better night's rest.
