The stiffness of the pillow is also determined by the posture during sleep. Those who are accustomed to sleeping on their sides need a hard pillow that supports the head and neck well. For people who are more comfortable to sleep on their backs, you can choose a medium stiffness pillow, and those who like to sleep on their stomachs need a softer pillow.
The filler and material of the pillow is the most important parameter that you should pay attention to when choosing it. The supporting capacity of the pillow, as well as the ability to ensure the correct position of your spine during sleep, depends on their properties.
Latex, anatomical foam, shape memory foam, and Taktile material are considered the highest quality fillers. They provide good head support and have excellent performance over a longer period of time.
Pillows made of down, feathers, buckwheat husks, padding polyester and other soft fillers to a lesser extent support the cervical spine, as they tend to wrinkle. In addition, such pillows are recommended to be changed 1 time in half a year, since they can form allergens and disease-causing organisms.
