Natural pillows
Usually made of feather and down, which is high in quality. These are a great option if you want your pillow to fit snugly or if you are looking for a firm, yet soft feel. These types of pillows also mould snugly around your head and shoulders.
Synthetic pillows
These are good if you suffer with allergies, fancy fresh, breathable comfort or want a memory foam filling. Manmade fibres also tend to be lower priced than natural fillings.
Consider your sleep style. Ask yourself: 'How do I sleep?' A pillow that is too firm or too soft can affect your posture. Remember to consider the pillow against your mattress; firm pillows don't tend to work well with a soft mattress.
