what’s inside?

Each tiny detail of the baby mattress has been thoughtfully designed to make sure your little one gets nothing but a safe, clean and supported sleep, throughout their early years.

the antibacterial mattress cover
The cloud-patterned cover is made from a special fabric that makes it super breathable. To make sure things stay as clean as can be, it can be unzipped in an instant and popped in the wash at 60℃
the waterproof protector
To protect the mattress from leaks, spills and a build up of any bugs, the springs and foam are covered by a waterproof membrane so nothing will get through to the core.
the luxury foam layer
The mattress won’t dip or lose any of that all-important support, thanks to quality, durable foam that protects the springs.
the premium pocket springs
High-quality, individual pocket springs adapt as your baby wriggles and grows, providing the ultimate support for their body. Springs also help the mattress breathe, helping your baby sleep cool as a cucumber. Cool, eh.

comfortably cool

comfortably cool

Not too hot, not too cold, a child’s temperature has to be just right. So we use a special fabric for the cover - a super soft, highly breathable two-layer material, separated by tiny dividers. It’s moisture-wicking and encourages air flow to keep tots comfortable. This clever technology makes it 400 times more breathable than standard mattress fabrics.

happy baby, happy parent

happy baby, happy parent

The baby cot mattress is designed for your little one’s comfort and safety. We use premium pocket springs topped with supportive, durable foam, so little backs, necks and heads get the long-lasting support they need as they grow.

The cover can be easily removed and popped in the washing machine. But for extra freshness, we’ve added a natural (and kind to skin) antibacterial treatment called Argentum. Bugs and allergens won’t stand a chance.
