Key Takeaways:
- Polyurethane is commonly used in waterproof mattress protectors, because it’s an effective waterproofing agent.
- Pure, solid polyurethane is a safe material for people and pets.
- Polyurethane foam, or polyfoam, is not a safe material because it releases toxic gases into the air in your bedroom.
- Look for certifications like OEKO-TEX Standard 100 to ensure the safety of a waterproof mattress protector.
Why Use Polyurethane in a Mattress Protector
Polyurethane is a plastic that’s often used in mattress protectors for its waterproof properties. When you’re dealing with spills, accidents, or even just the natural moisture that our bodies produce at night, a waterproof barrier is essential to keep your mattress clean and dry.
Is Polyurethane Safe?
There are two different types of polyurethane: pure solid and foam blend.
Pure, solid polyurethane is safe for your family, because it’s inert. Some mattress protectors use a form that’s graded as medical device biocompatible, which means it’s safe for medical use. On the other hand, watch out for “polyurethane foams” or “polyfoams” which are petroleum chemical blends. This form is referred to as “solid gasoline” by the National Association of State Fire Marshals.
Polyurethane Mattress Protectors: Safe
The material used in waterproof mattress protectors is a thin layer of pure, stable polyurethane. It’s sandwiched between layers of natural materials like organic cotton to create a waterproof barrier that breathes. Another type of polyurethane is called TPU (thermoplastic polyurethane). This is a newly developed version that’s biodegradable and recyclable. It’s manufactured with eco-friendly chemicals and no phthalates.
For peace of mind, you may want to check the label for a safety certification like OEKO-TEX Standard 100. This is your assurance that the product is a safer alternative for human health and the environment.
Polyurethane Mattresses: Not Safe
Many mattresses are manufactured using polyurethane foams due to their cushioning qualities, and they’re often labeled as “polyfoam”. These foams can “off-gas” or release volatile organic compounds (VOCs) into the air. These VOCs have been medically linked to respiratory issues and other health problems, and they’re especially dangerous for children, elderly, or anyone suffering from allergies or asthma. It’s a good idea to wrap these mattresses in a fitted style mattress protector or a zippered encasement mattress protector to minimize the dangers of off-gassing.

Frequently Asked Questions
1. Which form of polyurethane is safe in a waterproof mattress protector?
Pure, solid polyurethane is a safe product for people and pets. And TPU (thermoplastic polyurethane) is a biodegradable, eco-friendly version. Watch out for polyurethane foams or polyfoams. These are petroleum chemical blends, referred to as “solid gasoline” by the National Association of State Fire Marshals.
2. Can waterproof mattress protectors be waterproof and breathable so you don’t overheat?
Absolutely! A well-designed waterproof mattress protector can be both waterproof and breathable. Polyurethane and polyethylene are two waterproofing agents that have a micro-porous membrane. This allows air to circulate while preventing liquids from penetrating. It doesn’t trap heat like vinyl or plastics. So, you stay cool and comfortable all night long.
