The pillow is smaller than the mattress – but just as crucial for a healthy neck. An incorrect pillow can bend the cervical spine, leading to tension, even if the mattress fits perfectly.
The short answer: The right pillow supports your head so that the cervical spine forms a straight extension of the rest of the spine – neither bent upwards nor downwards. The ideal height depends primarily on your sleeping position.
Key takeaways
- Side sleepers: higher, supportive pillow (fills the space between shoulder and ear).
- Back sleepers: medium-height, supportive pillow.
- Stomach sleepers: very flat pillow or none.
- Goal: Cervical spine remains in a straight line with the rest of the spine.
Why the pillow is so important
The neck is the most mobile and sensitive section of the spine. If the head is too high, the neck is bent; if it's too low, it's overstretched. Both lead to tension, headaches, and restless sleep. The pillow has a clear task: to precisely fill the hollow space between the head, neck, and mattress. You can find more information on complaints in the article Neck pain from sleeping.
Which pillow suits which sleeping position?
| Sleeping Position | Pillow Height | Why |
|---|---|---|
| Side sleeping | High, supportive | Fills the space between ear and shoulder |
| Back sleeping | Medium | Supports the neck without lifting the head |
| Stomach sleeping | Very flat / none | Prevents overextension of the neck |
| Changing position | Adaptable | Responds to changes in position |

What is your sleeping position? The connection to the mattress
Pillow and mattress form a system. An adaptable mattress allows the shoulder to sink in – which also changes the required pillow height. Knowing your position allows you to choose both in a coordinated way. In-depth guides: Mattress for side sleepers and Mattress for back and stomach sleepers.
Pillow fillings at a glance
The filling determines support, climate, and care. Foam pillows (including viscoelastic) offer precise contour support and maintain their shape, while feathers/down are soft and conforming, and natural fibers excel in climate regulation. It is crucial that the filling maintains the appropriate height stably – a pillow that sags overnight loses its supportive function.

When you should change your pillow
Pillows wear out faster than mattresses. If the pillow visibly sags, smells despite care, or if you wake up with neck pain, it's time for a change. As a rough guide, one to three years is typical, depending on the material and care.

Frequently asked questions about pillows
What is the correct pillow height?
The height should fill the hollow space between the head and mattress so that the cervical spine remains straight. Side sleepers need a higher pillow, while stomach sleepers need a very flat one.
Which pillow is best for neck pain?
A supportive, shape-retaining pillow at the right height for your sleeping position. It's important that the neck is neither bent nor overstretched. More on this in the guide to neck pain.
How often should you change your pillow?
Depending on the material and care, approximately every one to three years – at the latest, when it sags or you wake up with tension.
