Hypnia mattress protector composition

The Hypnia mattress protector is made from a blend of 80% cotton and 20% polyester, which gives it a soft, breathable feel while ensuring durability.

It also has a waterproof thermoplastic polyurethane film.

This combination not only enhances comfort but also contributes to the protector’s effectiveness in shielding your mattress from wear and tear.

Conveniently, the Hypnia protector is OEKO-TEX certified [1] and guaranteed to be free from TCPP, parabens, and biocide chemicals. 🌱

What does sleeping on the Hypnia mattress protector feel like?

Sleeping on the Hypnia mattress protector feels surprisingly comfortable, and it doesn’t alter the feel of your mattress at all.

In testing the product for the Hypnia mattress protector review, I found that:

  • The surface of the mattress protector feels soft and smooth, so it didn’t alter the feel of my sheets.
  • The waterproof layer is effective but thin and doesn’t make any crinkly noises when you sleep.
  • The mattress protector has a very snug fit, so it stayed firmly put on the mattress and didn’t move around while I was sleeping.

Additionally, the mattress protector is very breathable, so it didn’t cause my bed to retain more heat during the night - a big plus for anyone who sleeps warm.


Since the waterproof nature of this mattress protector really stands out, here’s a quick overview to see how well the protector did:

As you can see, no water seeped through the protector, fully protecting my mattress.

This is in contrast to some other high-quality protectors like the Simba mattress protector, which is only water-resistant and not fully waterproof.

Why do you need a waterproof mattress protector?

Mattress protectors are designed to safeguard your mattress from dirt, stains, spills, bacteria, and dust mites.

While standard mattress protectors will offer protection from bacteria, dust mites, dirt, and stains, you’ll need a waterproof option to really protect your mattress against spills and moisture.

We’d always recommend waterproof mattress protectors, but you’ll find them particularly beneficial if the following apply:

  • You or your partner sweat heavily at night.
  • You frequently eat or drink in bed.
  • You or someone who shares your bed is prone to incontinence [2].
  • You or your partner are menstruating.
  • You have young children or pets that climb into bed with you.

Since mattresses are expensive, long-term investments, it always makes sense to protect your purchase as best as you can, and mattress protectors are the cheapest way to do so.

How to wash the Hypnia mattress protector

While you don’t need to wash your mattress protector as regularly as your bedding, it’s a good idea to pop it in the wash every few months for a good deep clean. 🧺

  • You can machine-wash the Hypnia mattress protector at 40℃ (the label says 60℃ but we have confirmed the washing temperatures with Hypnia customer support).
  • You can even tumble-dry the Hypnia protector at 60℃.

Just make sure to get the protector out of your tumble dryer as soon as the cycle is finished to avoid the film layer from resting too long in the hot drum.

How deep is the Hypnia mattress protector?

The Hypnia mattress protector has a depth of 35 cm (13.7 inches).

This is a good depth, ensuring it’ll fit over any type of mattress - and even fit well if you’re using a mattress topper over your mattress. 📏

Despite this extra-depth, I found that the protector sat super snuggly on my mattress, and I didn’t feel any extra material that could negatively impact my sleep.
