You peek in before bed. The mouth is hanging open again.
What you want is simple: soft breaths through the nose, lips resting closed, and a child who wakes up bright. It starts with what their head rests on tonight.
The face in next year's school photo is taking shape tonight.
On a pillow shaped for a grown-up, a small head tips back and the mouth drops open. The tongue rests low, the lower jaw sits back and breathing moves from the nose to the mouth.
How Nimbo works
Three zones. One goal: mouth closed, nose open.
Same child. Same night. Only the pillow changed.

Use it every night — consistency is what counts.
Frequently asked questions
What if their nights don’t get quieter?
Then you don’t pay for it. If your child isn’t sleeping more quietly with the mouth closed within 100 nights, send us one email and we refund you in full. Keep the pillow — there’s nothing to send back.
How quickly will I notice a difference?
Most children get used to Nimbo within the first few nights. The breathing you hear at the door usually gets calmer and quieter in the first one to two weeks, and the mornings change over the weeks after that. Use it every night — consistency is what counts.
Which size do I need?
Ages 1–3 small, ages 3–8 medium, ages 8–18 large. In between two sizes? Choose the larger one.
Is it safe? What is it made of?
A supportive memory-foam core inside a soft, breathable 3D honeycomb-knit cover, finished with navy piping. We recommend using it with a pillowcase: wash the case and the pillow stays fresh. Use Nimbo from age 1 — babies under 12 months should sleep without a pillow.
Tonight could be the first quiet night.
Tuck them in on Nimbo and listen at the door: soft breathing through the nose, lips closed — and in the morning, a child who wakes up bright.
