Waterproof Mattress Protector – What’s Safe and What to Avoid

A waterproof mattress protector is essential to protect your mattress from urine, spit-up, sweat and other bodily fluids that are part of life. Wet or damp mattresses provide a perfect environment for bacteria, mold, mildew and fungi, which can lead to a toxic sleep environment.

Plus, wetness can ruin your mattress!

Currently, the only way to get complete waterproof protection for a mattress is with a plastic lining or membrane in a cover or protector pad. But it’s important that you choose the right plastic, as not all plastics are the same. In fact, most can be quite toxic.

Most waterproof mattress protectors you find will be made of one of these plastics:

  • vinyl/PVC
  • PEVA/EVA
  • Polyurethane

Vinyl/PVC –Avoid it completely
Vinyl is dangerous on two levels. First PVC (polyvinyl chloride) is a known human carcinogen. Second, the plasticizers that are used to soften the hard PVC plastic and make it flexible enough to use as mattress protectors or pads are phthalates. Every day we learn more about how toxic phthalates (and phthalate variants) are, especially to babies’ and children’s small, developing bodies.

Phthalates make up 30%-40% of the weight of the vinyl surface, and have been linked to:

  • reproductive harm
  • asthma
  • early onset of puberty
  • cancer
  • kidney and liver damage

Even more alarming, they are weakly bound to the vinyl and leach or off-gas into the surrounding air, to be breathed in.

What about “non-toxic” or “phthalate-free” vinyl?
Due to the clear science that indicates phthalates are a health risk, several types of phthalates have been banned in the US. But manufacturers are always coming up with new variants, some only slightly different, that are legal and not tested for safety.

Until all of these variants are tested (if that ever happens), it’s better to avoid “non-toxic” and “phthalate-free” vinyl or PVC. No one really knows what level and type of plasticizers or additives in vinyl is safe, especially for children.

PEVA/EVA – Caution Needed
You may see products made with PEVA (Polyethylene vinyl acetate) or EVA (Ethylene vinyl acetate) touted as less-toxic than PVC. Although these types of vinyl are free of chlorine, they still may contain chemicals that are better avoided.

Polyurethane – Can be safe but do your research
Polyurethane on its own can be relatively safe, depending on how it’s formulated. It can be formulated with added chemicals or solvents. Polyurethane foam, for example is highly toxic due to additives to make it into a foam. You definitely want to avoid mattresses made with polyurethane foam, but the plastic is a different story. If you see a waterproof mattress protector made with polyurethane plastic, you’ll need to dig deeper to determine its safety. It’s difficult to know if a plastic is off-gassing, but sometimes the toxic smell will give it away.

Some other materials and factors to consider
Polyethylene – Safe but unsuitable for mattress pads
Polyethylene is a safe plastic. If you want to buy a MATTRESS that is already waterproof, then get a mattress that has a built-in covering made with polyethylene. Naturepedic makes a waterproof kids mattress and organic crib mattresses that are waterproofed with plant-based polyethylene made from non-GMO sugar cane.

Unfortunately, polyethylene is not ideal for mattress pads that need to be washed frequently, since it does not hold up wash after wash. It’s rare to find a polyethylene waterproof mattress protector on the market and if you do, don’t expect it to last long.

Coating – not worth the risk
Some mattress pads are marketed as anti-microbial, antibacterial and/or anti-mildew. Usually this means the pad has an extra coating of something that’s potentially toxic. If you wash the pad when needed, coating is unnecessary. Better to avoid inviting other chemicals into your bed.

Wool Mattress Pads – a natural, safe option but not entirely waterproof
Since wool is moisture-resistant and dries quickly, wool mattress or “puddle” pads are sometimes used with mattresses that are not waterproof. Many wool puddle or piddle pads actually have synthetics in them, such as polyester, so look for 100% certified organic wool from a company you can trust. Keep in mind that wool can also be allergenic.

You can’t count on wool alone to waterproof a mattress. If there is a lot of wetness from a baby or child, it can go through to damage the mattress and create mold and mildew problems. I recommend layering one or two organic wool puddle pads that are specifically designed to block wetness with an organic cotton mattress protector to serve as extra layers of protection. Cotton absorbs moisture and wool repels and wicks moisture away. When used in concert, the wool and cotton pads together can block the wetness, but don’t count on it being completely waterproof.

What do I recommend for a guaranteed non-toxic, 100% waterproof mattress protector?
I searched everything on the market, and I recommend either the Sleep and Beyond Organic Cotton Waterproof Mattress Protector or the Naturepedic Organic Waterproof Protector Pad since neither have toxic chemical additives. They do not leach chemicals or off-gas into your sleeping environment. They are both confirmed non-toxic, and hypo-allergenic. Both are made with an ultra-thin film of polyurethane plastic completely surrounded by two layers of organic cotton, and both can withstand even the worst nighttime accidents while still allowing the material to breathe. There’s no plastic chemical odor and the organic cotton provides a non-sweaty sleep surface.

What’s the difference between the two? The main difference is the Sleep and Beyond protector is waterproof on the skirt/sides as well as top so the sides of the bed are protected too. The Naturepedic protector is only waterproof on the top and the fitted sides are not. In my opinion, the Sleep and Beyond feels softer and more comfortable. The Sleep and Beyond has a slightly higher price because of all of this.
