Choosing Your Mattress
We've matched the Stokke Sleepi Bed Extension with two of our natural fibre nursery mattresses - the Coco Mat & the Latex Mat.
For newborns and babies we recommend our Coco Mat. Made with a core of organic coir (coconut fibre) and padded with breathable certified organic wool, the Coco Mat provides a firm & flat sleep surface, as recommended for babies by the Lullaby Trust. Although it was designed with newborns in mind, the Coco Mat can be used well into their toddler years.
If you're planning on moving a toddler into the Sleepi Bed, we would suggest our Latex Mat. The layers of natural latex, organic coir and organic wool inside this mattress provide more supple natural support for their growing bodies.
Our quilted mattress covers are removable and washable and require no chemical fire retardants thanks to their tightly-woven cotton & wool outer. Finished with a plant-based, OEKO-tex certified treatment, our covers are also entirely hypoallergenic & dust mite resistant.

About Stokke
Ever since they launched their iconic Tripp Trapp chair in 1972 Norwegian brand Stokke have used their passion for Scandinavian design to create simple, striking nursery furniture that challenges the ordinary and nurtures family bonding.
Stokke's aim is to bring children closer to their parents - physically and emotionally - by producing quality, stylish products that are built to last from natural & chemical-free materials.
We're proud to offer Stokke's Sleepi range as well as a host of mattresses, protectors & organic cotton bedding made to fit.

Our Mattresses
Over twenty years ago, we created the first baby mattress made from entirely natural fibres. We knew then that when it comes to where your child sleeps, organic and natural materials are simply better - for them, and for the planet.
Natural fibres are breathable, supportive, comfortable, naturally hypoallergenic, and help your little one better regulate their body temperature. This all adds up to better sleep.

Naturalmat Baby & The Lullaby Trust
We are very proud to be working in partnership with The Lullaby Trust to champion their safer sleep advice and help all families give their babies the best start in life.
The safest mattresses for your baby are firm and flat and protected by a waterproof cover, which is why we include a waterproof mattress protector by default (additional charges apply). Of course you’re welcome to remove it if you already have one, but it’s important to ensure that it fits the mattress you’re buying.
