This clever 'dual core' breathable Tiny Dreamer Natural™️ Travel Cot 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 own 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 fibres stripped from raw coconut shells. It has a dense & bouncy feel which provides the perfect firmness to support a newborn baby and beyond, as recommended by safety sleep experts.
