Let customers speak for us
We offer two sizes:
• 0 to 6 months: 70 cm long. Not extendable.
• 6 to 18 months: 80 cm long and adjustable to 65 cm using the rear buttons.
Don’t worry too much about the weight. Measure your baby’s length and choose the size accordingly. The sleeping bag has snap buttons to adjust the fit around their body.
The 0-6 month model can be used from the first month, but we recommend waiting until the baby weighs at least 3 kg and has some arm mobility. If in doubt, reach out to us on WhatsApp.
This is a 2.5 TOG model. It’s ideal for room temperatures between 16ºC and 20ºC (cool rooms, mild winters, homes without strong heating). Not recommended for summer or rooms above 21ºC.
No. It’s 100% cotton with certified Oeko-Tex filling that retains warmth without overheating. Parents say it’s warm but breathable — cozy, not stifling.
Yes. All fabrics are certified OEKO-TEX Standard 100. Free from toxins, dyes, and pesticides. Safe for sensitive skin.
Extremely. Here’s why:
• Double zipper with fabric cover to prevent rubbing.
• Snap buttons on sleeves to prevent arms from slipping inside.
• Rear clips to reduce length and avoid excess fabric.
• Official safety certifications in the UK, Europe, and the US (BS 8510:2009, EN 16781, CPSC & CPSIA).
Of course. Up to 60ºC. The fabric is durable and air-dries well. If tumble drying, use low heat.
It’s thicker than some sleeping bags, so it may take a bit longer. We recommend natural drying. Avoid ironing.
Yes. The double zipper lets you open just the bottom part for diaper changes without fully undressing your baby. Many parents highlight this as a key feature
Not at all. It comes neatly folded in a compact box — perfect for gifting. It’s not feather-filled, but cotton-based: cosy yet manageable.
The ergonomic design and adjustable buttons help it stay put. It won’t twist or come loose during even the most restless nights.
Safety, thoughtful design, and lasting quality. This product has been tested by hundreds of families, passed all EU and US safety tests, and is built to last.
Yes. You have 100 days to try it out. But fair warning: very few come back. Ask the parents already using it.
We get it — it feels like a lot for one item. But after a week of use, you’ll wonder how you ever managed without it. A good sleeping bag isn’t a luxury — it’s better sleep for everyone.
Now it’s your move.
They say babies don’t come with a manual.
But some products feel pretty close.
This sleeping bag? It’s the one thing parents keep buying again, gifting to others, and raving about in the reviews.
Not perfect. But close.
Try it for 100 nights. Sleep on it — literally. If it’s not for you, send it back.










Once you try it, there’s no going back.
Sleep changes. Nights feel lighter.
And every parent ends up saying the same:
“Why didn’t we get this sooner?”
