Welcome to a new form of filling where the feeling is soft, yet there is a medium firmness to the pillow. Furthermore, it feels like there is structure and support. Strange you might think, but that is exactly what we are trying to achieve with this pillow. The unique filling is a blended mix of microfiber and shredded memory foam. The microfibre part provides the soft bounce to the pillow which you might expect from an expensive feather filled pillow. The shredded memory foam, which is infused with blue cooling gel, provides structure and support, moulding to your head shape whilst you sleep, but not too much like a full on foam pillow. The cooling gel infused foam also helps to make the pillow a little less heat retentive. Overall, the result is a surprisingly comfortable pillow for those who prefer more support, who don’t like super soft pillows, but still want a little bit of softness. This pillow is about medium firmness, but if you like really firm pillows, you can always contact Martian Made to get more filling as well. On top of all that, we are offering a decent 5 year warranty on the product. This is a pillow made by Martians, for Humans, but suitable for all!.
