The Shima children's pillow has a siliconised hollow fibre core that promotes air circulation, dissipates humidity and heat and acts as an excellent temperature regulator. The outer lining of the Shima cushion is made of 100 per cent cotton, which makes it very breathable. Cotton allows the skin to breathe naturally and allows sweat, which can occur during rest, to dry easily. This fibre does not deform over the years, which means it will always maintain the right firmness for the correct alignment of the child's spine, from the age of 2 until adolescence. Very soft and cuddly to the touch. The silicone fibre makes it flexible, adaptable and soft.
