Below you’ll find our top picks, each scored on our 0, 10 BP Score.

Best Mattress Protector Waterproof Buying Guide

Material and Breathability

The fabric of a waterproof mattress protector directly affects how cool and comfortable you sleep. Cotton, bamboo-derived viscose, and Tencel are common top layers that wick moisture and allow airflow.

Bamboo and Tencel options often feel silkier and naturally help regulate temperature, while cotton covers are more traditional and breathable.

Avoid protectors with a stiff, plastic-like feel, quality models use a waterproof membrane (often polyurethane) that’s bonded to a soft fabric so you get protection without noticeable crinkle or heat retention.

For more on cooling materials, see our mattress toppers guide.

A breathable design is especially important if you sleep hot or live in a humid climate. Look for terms like “breathable membrane” or “vapor-permeable” in product descriptions.

Verified buyer reviews frequently mention whether a protector sleeps cool or traps heat, so we weighed that feedback heavily.

Many top-rated protectors also have a noiseless construction, the thin membrane doesn’t rustle when you move, so you won’t be reminded that a protector is there.

Waterproof Layer and Leak Protection

The core job of any waterproof mattress protector is to stop liquids from reaching your mattress. The best models use a polyurethane (PU) laminate or a TPU (thermoplastic polyurethane) coating that is 100% waterproof yet thin and flexible.

PU laminates are common and effective, but TPU is often more durable and stays flexible after many washes. Check that the waterproof layer covers the entire top surface and extends down the sides, especially if you use a deep mattress.

Some protectors also add a stain‑resistant or antimicrobial finish to inhibit mold and bacteria. While not essential, these extras can be helpful for allergy sufferers or homes with pets.

Always check the care instructions, a machine‑washable protector that you can dry on low heat is far easier to maintain.

Fit and Pocket Depth

A good fit is crucial, a protector that shifts or bunches up will ruin your sleep surface. Most protectors have a fitted sheet style with an elastic skirt.

The pocket depth (how tall a mattress it can accommodate) is usually listed as a range, like 8, 18 inches.

If you have a thick pillow‑top or an adjustable base, choose a protector with deep pockets (at least 15 inches) and a strong elastic band that grips the corners.

Many protectors today come in sizes from Twin to California King, and some brands offer split models for adjustable bases with separate head/foot sections.

Always measure your mattress thickness before ordering to ensure the pocket depth covers your mattress without leaving any gap. A snug fit also prevents the protector from wrinkling under your sheets.

Care, Durability, and Certifications

A waterproof mattress protector should withstand frequent washing without losing its waterproof ability. Look for protectors that are fully machine washable and dryable, the best ones maintain performance after 50+ wash cycles.

Verified buyer feedback often notes whether a protector delaminates or gathers after repeated laundering. Brands like SafeRest and PlushDeluxe have a long track record of durability in this category.

Certifications add peace of mind. The most relevant certifications for bedding are OEKO‑TEX Standard 100 (evaluated for harmful substances) and CertiPUR‑US (for foam components, if any).

While BestProducts does not conduct product trials, we prioritize protectors that publish clear material safety and care information. For non‑toxic options, see the best non toxic mattress protector.

Frequently Asked Questions

Do waterproof mattress protectors make you sweat?

Not necessarily. Modern waterproof protectors use a breathable membrane that allows air and moisture vapor to pass through while blocking liquid. Models made with bamboo viscose, Tencel, or cotton blends often sleep just as cool as a regular fitted sheet.

To minimize heat buildup, choose one labeled “breathable” or “cooling.”

Can you wash a waterproof mattress protector in the washing machine?

Yes, most are machine washable. Use cold or warm water on a gentle cycle and avoid fabric softeners, which can degrade the waterproof coating. Tumble dry on low heat or air dry. High heat can damage the membrane, so always check the care label.

How often should you replace a waterproof mattress protector?

Most high‑quality protectors last 2, 5 years with regular washing. Signs it’s time to replace include visible wear, loss of waterproofing (liquid soaks through), or pilling that makes the surface uncomfortable. Brands like SafeRest have a reputation for maintaining performance for years.

Will a waterproof mattress protector fit a pillow‑top mattress?

Yes, as long as the pocket depth covers your mattress height. Pillow‑top mattresses are often 14, 18 inches thick. Choose a protector with deep pockets (18, 21 inches) and a strong elastic skirt to prevent shifting. Many protectors in our list accommodate up to 21 inches.

Can I use a waterproof mattress protector on an adjustable bed?

Absolutely. Most fitted‑style protectors work fine with adjustable bases, but you should ensure the protector has enough fabric to flex without bunching when the head or feet are raised. Some brands offer split designs for split‑king adjustable beds.
