The Best Waterproof Mattress Cover

Protecting your mattress from spills, allergens, dust mites, and wear is essential for extending its life and maintaining a hygienic sleep environment. A waterproof mattress cover acts as an invisible shield, preserving your investment without sacrificing comfort.

In this guide, we have evaluated dozens of options based on specifications, expert review consensus, and verified buyer feedback to help you find the right protection for your bed. Our top picks are listed below.

Best Waterproof Mattress Cover Buying Guide

Material and Comfort

The fabric of a mattress cover directly affects sleep comfort. Cotton and polyester blends are common, but bamboo-derived rayon and Tencel offer a softer, more breathable feel.

Look for covers that are noiseless and smooth against the skin, especially if you sleep on a memory foam or latex mattress.

Many premium options use a terry cotton top for added absorbency, while others feature a quilted design for extra plushness.

If you value a luxurious hand feel, consider covers made from rayon derived from bamboo or Tencel, which also help wick moisture away.

For hot sleepers, breathability becomes critical. A waterproof barrier that traps heat can lead to night sweats. Covers with a breathable polyurethane (PU) membrane or those that advertise cooling properties (like phase-change materials) can maintain airflow while still blocking liquids.

Some covers combine a cotton surface with a waterproof backing to balance comfort and protection. For more tips on creating a comfortable sleep setup, see our comprehensive sleep & bedding guide.

Waterproof Technology

Not all waterproofing is equal. The most reliable covers use a thin polyurethane laminate or a membrane that blocks liquids while allowing vapor to escape. Some older designs use PVC, which can be less breathable and noisier.

A high-quality waterproof cover should withstand repeated washing without delaminating or losing effectiveness. Verified buyer feedback often highlights how well a cover holds up after six months or a year of use.

For the best performance, look for covers that mention “100% waterproof” and have positive long-term reviews.

Zippered encasements offer the highest level of protection by covering the entire mattress, including the sides. This is especially important for allergy sufferers, as it blocks dust mites and allergens from both the top and bottom.

If you only need to protect against spills, a fitted sheet style may suffice. For more details on choosing the right style, visit our dedicated mattress protector guide.

Fit and Depth

A cover that doesn’t fit properly will shift during the night, bunch up, or leave gaps. Measure your mattress height before purchasing.

Most standard covers accommodate beds up to 12 inches, but many now offer extra deep pockets (14 to 21 inches) to fit thicker mattresses, pillow tops, and mattress toppers. Look for covers with elasticized skirts or a full encasement design that stays taut.

Some covers include side zippers for a snug fit. Mattress depth is often listed in product specifications; choose one that matches your bed. If you use a mattress topper, account for that extra height when selecting a cover.

Breathability and Noise

Waterproof covers have historically been associated with a crinkly feel and trapped heat. Fortunately, modern designs have largely solved these issues. Breathable waterproof membranes allow air circulation while stopping liquids, reducing heat accumulation.

Many covers now use a combination of natural fibers and thin polyurethane layers that remain quiet and pliable.

User reviews frequently mention whether a cover is “noiseless” or “soft and quiet.” To enhance overall sleep comfort, consider pairing your cover with high-quality bed sheets made from breathable materials like cotton or linen.

Care and Durability

Easy maintenance is a key factor. Most waterproof mattress covers are machine washable, but you should follow the care label to avoid damaging the waterproof membrane.

Washing in cold water on a gentle cycle and tumble drying on low heat is standard. Avoid fabric softeners and bleach, as they can break down the barrier. Durable covers maintain their waterproofing for dozens of wash cycles.

For long-term use, look for covers with reinforced seams and a high stitch count. If you value a clean sleeping environment, you might also be interested in moisture control dehumidifiers to reduce humidity in the bedroom.

Allergy and Hypoallergenic Properties

For individuals with allergies or asthma, a waterproof mattress cover can act as a dust mite barrier. An encasement that zips around the entire mattress provides the best defense, sealing in allergens and preventing new ones from settling.

Some covers are specifically marketed as hypoallergenic or allergy-proof, often with a pore size small enough to block common allergens. These covers may also undergo third-party certification.

If you have severe allergies, pairing a cover with hypoallergenic pillows and washing bedding weekly can make a noticeable difference.

Frequently Asked Questions

Do I need a waterproof mattress cover?

It depends on your lifestyle. A waterproof cover is highly recommended for households with young children, pets, or anyone who eats or drinks in bed.

It also provides a barrier against dust mites, mold, and allergens, making it beneficial for allergy sufferers. Even if you don’t have spills, the cover protects against sweat and body oils, extending the life of your mattress.

Can I use a waterproof mattress cover with a mattress topper?

Yes, but you need to account for the combined height. Measure your mattress plus topper thickness and choose a cover with deep pockets that can accommodate the total. Some covers are designed to fit up to 18 inches or more.

If your topper is very plush, a fitted cover with strong elastic works best to prevent shifting.

How often should I wash my waterproof mattress cover?

Follow the manufacturer’s instructions, but generally, washing every two to three months is adequate for most households. If you have allergies or if there is a spill, wash it immediately.

Use mild detergent on a gentle cycle and avoid fabric softeners, which can degrade the waterproof layer. For added freshness, you can also vacuum the cover between washes.

Will a waterproof mattress cover feel hot or noisy?

Modern covers with breathable waterproof membranes are designed to be noiseless and temperature neutral. Many users report that high-quality covers made with cotton or bamboo rayon feel just like regular sheets.

To minimize any heat retention, choose a cover that specifically mentions breathability or cooling properties.

Are zippered encasements better than fitted sheet styles?

Zippered encasements offer full protection for the entire mattress, including the sides and bottom, making them ideal for allergy control and complete spill coverage. Fitted sheet styles are easier to install but only protect the top and sides.

If you want the highest level of protection, a zippered encasement is recommended. For everyday protection from spills, a fitted style is sufficient and simpler to maintain.

How long does a waterproof mattress cover last?

With proper care, a quality cover can last three to five years or more. Factors include the frequency of washing, the type of waterproofing material, and overall construction.

Look for covers with reinforced seams and a high thread count if you want durability. Signs of wear include delamination, cracking, or loss of waterproofing. Replacing the cover when it starts to degrade ensures your mattress stays protected.
