Elevate your baby's sleep environment naturally. This clever 'dual-core' breathable mattress is filled with some of the world's finest 100% sheep’s wool & organic coconut coir. We use 100% sheep’s wool for its natural thermoregulating properties, which is essential for newborn babies who cannot regulate their body temperature until they are around 3-4 months old—benefiting from a blissfully comfortable sleep no matter the season. The two generous layers of 100% sheep’s wool cushion a chunky layer of luxury organic coconut coir. Our coconut coir is created from shredded coconut fibers stripped from raw coconut shells. It has a dense & bouncy feel, providing the perfect firmness to support a newborn baby and beyond, as recommended by safety sleep experts. The two serenely simple natural fillings will leave your child lovingly cradled while sleeping. This mattress is naturally hypoallergenic and anti-dust mite thanks to its beautifully simple, chemical & toxin-free filling. Carefully curated by expert craftsmen in the UK, you can rest assured that our mattress has been built without any nasty chemicals. We are dedicated to building our mattresses to specifications that comply with the rigorous requirements of BS 1877 Part 10 for safety & performance and BS 7177 for flammability without using any antimony, phosphorous, or arsenic-based fire-retardant treatments. This mattress can be used from birth and is guaranteed up to the weight of 8 stone.
