The organic cotton mattress protector is ideal for those looking for lightweight, breathable, and easy-to-care protection. It is particularly suitable for warm climates and people who prefer a cool sensation.

The wool mattress protector, on the other hand, offers superior moisture absorption (up to 30% of its weight) and exceptional temperature regulation. It is recommended for families with young children, elderly people, or those looking for maximum protection.

No, this mattress protector is not waterproof. It is designed to be breathable and absorbent, which promotes air circulation and prevents heat buildup. It absorbs body moisture and skin oils, but is not designed for significant liquid spills.

For water-resistant protection while remaining natural, we recommend our organic wool mattress protector, whose natural fibers repel moisture.

Machine wash in cold water with a mild, preferably eco-friendly detergent. Use the delicate cycle to preserve the fibers. Dry on low heat in the dryer or air dry to extend its lifespan. Avoid bleach and harsh chemicals that could damage the organic cotton.

Absolutely. GOTS-certified organic cotton is naturally hypoallergenic because it is grown without pesticides, herbicides, or irritating chemicals. Its breathable structure also discourages dust mite proliferation, making it an excellent choice for people suffering from allergies or asthma.

Yes! Thanks to its peripheral elastic and 4-way stretch fabric, this mattress protector fits perfectly on mattresses up to 16" (40 cm) thick. It is therefore suitable for standard Obasan mattresses, as well as mattresses with integrated toppers.

Yes, you have two options:

  1. Place the mattress protector directly on the topper, then place the topper on top of the mattress.
  2. Place the mattress protector over both the topper and the mattress to protect the entire sleep system.

The second option is recommended if your topper is thin and the combined height does not exceed 16".
