For parents of children under 9

Every night on the wrong pillow shapes your child's face in the wrong direction.

The drooling, the snoring, the open mouth. Around age 9 this development sets. At 14 braces often follow, at 18, in the worst cases, jaw surgery. Children's airway specialists see it every day.

Change pillows tonight.

Children's airway specialists see it every day, yet almost no parent has ever heard of it. If your child sleeps night after night with their mouth open on the wrong pillow, four things happen at once: the tongue slips back, the lower jaw recedes, the palate becomes narrow and high, and the face grows long instead of wide.

Between 3 and 9 all of this adds up, over thousands of nights. Around age 9 the palatal suture ossifies, and from then on the shape is largely set. That is why so many nine-year-olds end up at the orthodontist with a receding chin, dark circles and crowded teeth. The 3-zone structure of the Arcastral pillow keeps head, neck and jaw correctly aligned from the very first night and encourages nose breathing while development can still be shaped.

The common belief is only half true. Yes, the palatal suture closes around age 9. But the face keeps developing until around 20 and the lower jaw grows until about 17. Every night of mouth breathing after the ninth birthday adds new damage to what is already done: teeth grinding, headaches, sleep that doesn't rest, falling concentration and the tiredness so many mistake for laziness. Your teenager isn't lazy, they struggle to breathe at night.

That is why the Arcastral pillow also comes for older children and teens (about 8 to 18): different profile, different height, different support for a bigger head and neck, same mechanism. Parents tell us snoring drops within 7-14 nights, energy returns in the morning and concentration improves. The best period is still between 3 and 9, but a lot can still be done between 8 and 18. No window is fully closed, but every night of waiting counts.

Let your child sleep 30 nights on the Arcastral pillow. If by then you don't see less mouth breathing, softer snoring, no more dry mouth in the morning and calmer sleep, send us a short email. We refund you down to the last cent. No questions, no hidden clauses, no need for the original packaging.

Always the bigger one. The pillow is made to keep the right alignment while your child grows, so you can use it for longer.

Your child presses their face against this pillow for up to ten hours a night. That is why we had the cover fabric tested by an independent laboratory, to the strictest safety class for baby textiles:

  • Formaldehyde not detectable, below the strictest limit for baby textiles.
  • No banned azo dyes. The full test for 24 carcinogenic dyes came back negative.
  • Skin-friendly pH, in the range recommended for direct skin contact all night long.
  • Saliva-resistant, top grade for colourfastness: nothing comes off if your child drools on or sucks the fabric.
  • Resistant to sweat and washing, no fading, the colours don't run.
  • Odourless, no chemical smell straight out of the box.
  • Breathable: a lyocell and cotton mesh insert wicks away moisture and keeps the surface cool and dry.

Our team processes every order within 48-72 hours. Delivery takes about 5-12 working days, depending on where you are. Returns are covered by our 30-night money-back guarantee: if you're not happy, just write to us.

Developed with paediatric airway dentists

Tonight you can start reversing the silent damage.

Children's airway specialists warn about the same silent problem: children who snore and breathe through their mouth don't just sleep badly. Jaw, palate and face shape can slowly develop in the wrong direction.

And the window to correct it doesn't stay open forever.

The Arcastral kids pillow was created to keep head, jaw and airways in the right position during sleep, which encourages nose breathing and healthier facial development, while it still counts.

It isn't just a pillow. It is night-time airway support in exactly the years that shape your child's face.

Tonight you can start reversing the silent damage.

The right support for head and neck is essential for healthy sleep.

An ergonomic kids pillow keeps head and neck in their natural alignment and stops the head tipping sideways during the night. So the spine stays straight, even if your child moves a lot in their sleep.

The result is calmer sleep and better rest.

The right support for head and neck is essential for healthy sleep.

Designed to protect your child's face as it grows

Mouth breathing in early childhood can deform a growing face. Arcastral keeps head and jaw aligned so your child breathes through the nose.

Frequently asked questions

How soon will I see the mouth breathing stop?

Most parents already notice in the first 5-7 nights calmer breathing and fewer open-mouthed wake-ups. Around the fourteenth night the snoring stops and the lips stay closed all night. Visible changes to the jaw, alignment and dark circles usually appear between day 21 and day 30. Use it every night: the effect builds up.

Arcastral is designed for children from 3 to 9, the decisive window in which palate and jaw are still growing and the damage from mouth breathing can still be reversed. The palatal suture ossifies around age 9. There is also a smaller version for ages 1-3 and a bigger one for ages 9-18.

Arcastral is made of hypoallergenic OEKO-TEX certified memory foam: no formaldehyde, no heavy metals, no BPA. Anti-dust-mite and breathable.

For everyday use we recommend a separate pillow cover. Slip it off and wash it, and the pillow stays clean. The pillow is washable, but do not bleach, iron or dry clean it. We don't recommend machine washing, and if you really need to, put it in a laundry bag on the delicate cycle. Then hang it to dry and plump it up a little.

Yes. The ergonomic shape supports without bothering. Most children get used to it in 1-2 nights and then don't want any other pillow. There's no right position to make them take, and no bedtime battles.

Yes, that is exactly what it's made for. The 3-zone structure stops the head tipping back and the mouth falling open. Within 7-14 nights the lips close by themselves and nose breathing returns. The longer your child has breathed through their mouth, the clearer the change will be.

Let your child sleep on the pillow for 30 nights. If you see no improvement in mouth breathing, snoring, dark circles or jaw alignment, write to us and we refund you down to the last cent. No questions, no hidden clauses, no need for the original packaging.

My son is prone to allergies, so a clean surface mattered to me. We also got two covers and we alternate them. He sleeps better and breathes better. Happy with the choice.

So soft on the skin, the right size for a child and you can tell it's made for the neck. My little one falls asleep quickly and stays settled. Perfect.
