Complete protection for your mattress

To ensure your perfect night’s sleep, we’ve incorporated the most advanced technologies, including Cairfull, Purotex+, and Adaptive. Together, these innovations make our mattress protector everything a healthy sleep environment should be. It protects against sweat, skin cells, and moisture, while also creating an exceptionally fresh and breathable sleeping experience—unlike standard mattress covers. In fact, many customers tell us their mattress feels even more comfortable with this protector on.

01

How does CAIRFULL enhance ventilation?

Did you know your sleep environment has its own microclimate? The quality of your pillow and sleep surface plays a big part in your comfort, and both need to be breathable for a healthy sleep environment. CAIRFULLâ„¢ technology provides up to 400 times more airflow than a regular mattress or pillow cover, while drawing away excess moisture and heat. This clever technology creates a layer of air between your head and pillow, ensuring optimal pressure relief and a cool, comfortable sleep surface.

02

What is Purotex+ for?

Purotex+ is a natural probiotic that offers exceptional protection against allergens. It reduces dust mite allergens by 96.6%, cat hair allergens by 83.6%, and dog hair allergens by 76.5%. What’s more, it’s 100% bio-based and stays effective even after 20 washes.

03

How does adaptive cooling work?

Adaptive is a unique technology that makes this mattress protector a dynamic product, responding to changes in temperature. The warmer you get, the faster the Adaptive treatment works to evaporate moisture. This quick evaporation reduces humidity and keeps you cool.

04

Can I use the mattress protector with just my mattress topper?

The elastic sides of the mattress protector are designed for mattresses that are at least 20 cm deep. However, it can also be used with a mattress and topper together, as long as the total thickness doesn’t exceed 30 cm.

05

How do I wash the mattress protector?

The mattress protector can be machine washed at 60°C for easy care and long-lasting freshness.

Materials of the mattress protector

This mattress protector has been specially designed to keep your sleep environment clean and hygienic. That’s why we’ve chosen only the finest materials that contribute to this goal.

For optimal washability, we’ve used 100% virgin polyester yarn at 338 g/m², allowing the mattress protector to be washed at 60°C. What makes this fabric unique is the special weaving technique used for the yarn. This creates a three-dimensional cross structure that forms an air layer between you and the sleep surface. Additionally, the fabric is treated with Purotex+ and Adaptive, providing anti-allergenic properties and a cooling effect.

Your mattress and mattress topper deserve the best protection

With a mattress protector, your mattress and topper stay protected against everyday wear and tear for longer. This ensures your sleep surface retains its firmness, comfort, and hygiene, even after years of use.

Customer success stories

StarStarStarStarStar

I swapped my old mattress for a Morningstar mattress. I used to have frequent back and neck pain, but luckily, those are gone now. Highly recommended! Plus, the company provided excellent service.

We ordered the Morningstar bed **Bela** (200×200) with two 18cm mattresses and a mattress topper—what an experience! With three kids regularly jumping into bed, we needed the space. The reversible mattresses combined with the mattress topper are the perfect solution for a great night's sleep, especially with the weight difference between my wife and me. We are absolutely thrilled with this purchase! And the luxurious look is a feast for the eyes.
