For those who sleep in a supine position, the ideal pillow is made of latex or memory foam, soft and of medium thickness.

For those who sleep in the prone position (on their stomach), the choice will be between soft and low latex or memory pillows.

Those who sleep on their side require a harder, medium-thickness latex or memory pillow.

For those who sleep in alternating positions, i.e. turning over and over several times in their sleep, the ideal pillow is a hard or soft latex pillow of medium height.
