We are one of only a few companies globally to meet the stringent requirements of BSEN 1130.

But if you’re curious about what makes our newborn sleep solution a cut above the rest, let us explain what makes the Treasured Baby Box one of a kind.

Our Baby Box is a labour of love, following months of research to ensure Arvossa meets the expectations of discerning mums and dads. Inspired by Finland, born in Harrogate, we took the concept and wanted to make it better!

Every inch of our box has been certified safe, from the hypoallergenic mattress to the metal-free, toy-grade ink used on our gorgeous print. So you can feel confident that your baby is safe and sound when nestling down in their sleeper.

Safety is the main reason you won’t find any handles on our Baby Box We strongly advise against carrying the box with your little one inside, which is why our version, unlike others, has no handles to grab onto.

Sleep easy knowing your little wonder is safe and snug…

We know that safety is of tip top importance for all mums and dads, which is why we settled for nothing but the best when designing our box.


Our Treasured Baby Box arrives with a full list of safety instructions inside, to answer any common questions parents have about using this newborn sleep solution. Make sure you read this carefully and keep it somewhere safe.

If you have any questions about the design and functionality of our Baby Box, we’d be all too happy to hear them! Simply get in touch with our team and we’ll do our best to answer them.
