There are many different types of pillows. The most common pillows are stuffed with either a synthetic fiber or feathers. Memory Foam pillows come in various shapes and sizes and can be made from many small memory foam pieces or just a solid memory foam block. They can have gel pads on top of the foam, be infused with gel or perforated to help keep the pillow cool. Pillows also come in various sizes and thicknesses.
Many people with neck problems prefer a thinner pillow while others prefer a thicker luxurious pillow.
Pillows are as unique as you are, so it is best to try out as many different pillows before deciding on which one is best for you!
