Brief answer: Morning neck pain often comes from the wrong pillow. The pillow must fill the space between the shoulder and head to keep the cervical spine straight. Side sleepers need a higher, more supportive pillow (10–15 cm). Back sleepers need a medium-high pillow (8–12 cm). Stomach sleepers need a flat, soft pillow (max. 6 cm). A 3-chamber pillow offers the best combination of support and adaptability.
You wake up in the morning and your neck is stiff. Turning your head causes a pull, sometimes the pain radiates into your shoulders. If this happens regularly, it's rarely due to a serious illness — but usually to your pillow.
A wrong pillow puts the cervical spine in an unnatural position — night after night, for six to eight hours. Too high, and the neck bends forward. Too flat, and the head sinks. Too soft, and there's no support. The result: tense muscles, irritated nerves, chronic neck pain.
As pillow manufacturers, we at BEFA have been concerned since 1994 with how a pillow can optimally support the neck. In this guide, we explain which pillow height and filling suit which sleeping position — and why the right pillow can not only relieve neck pain but also prevent it.

Why the wrong pillow causes neck pain
The cervical spine has a natural lordosis — a slight forward curvature. When standing and sitting, the neck muscles maintain this curvature. During sleep, the pillow takes over this task.
If the pillow is too high, the head is pushed forward. The cervical spine hyperextends, the posterior neck muscles are overstretched, and the anterior ones are shortened. The result after 7–8 hours: tension that resolves during the day — or becomes chronic.
If the pillow is too low, the head bends to the side (for side sleepers) or backwards (for back sleepers). The intervertebral discs between the cervical vertebrae are unevenly loaded, and nerves can be irritated.
The ideal pillow fills the space between the shoulder and head exactly, so that the cervical spine maintains its natural position — in a straight line with the thoracic spine. This varies for each person, as shoulder width, head size, and mattress firmness differ.
The right pillow height for your neck
Pillow height is the most important factor for neck pain — more important than material, size, or price. The optimal height depends on two variables:
1. Your sleeping position
- Side sleepers: 10–15 cm (the space between shoulder and head is largest)
- Back sleepers: 8–12 cm (the head needs to be slightly elevated, not bent)
- Stomach sleepers: 3–6 cm (almost flat, to avoid hyperextension of the neck)
2. Your shoulder width
Wide shoulders = higher pillow. Narrow shoulders = lower pillow. This applies particularly to side sleepers, because shoulder width directly determines how much space the pillow needs to fill.
Simple self-test: Lie down in your sleeping position and have someone check from behind if your spine forms a straight line. If your head is bent up or down, the pillow height is not correct.
From our production: For neck problems, we recommend a 3-chamber pillow. The advantage: You can adjust the height individually by removing or adding filling from the outer chamber. This way, you find the exact height for your sleeping position and shoulder width — without having to buy multiple pillows.
Choose a pillow based on sleeping position
Side sleepers — the most common position
Around 60% of Germans sleep on their side. In this position, the distance between the head and the mattress is greatest, because the shoulder is in between. The pillow must completely fill this space.
Ideal for side sleepers with neck pain:
- Pillow height 10–15 cm (depending on shoulder width)
- Firm to medium-firm filling that does not give way too much
- Feather pillows or 3-chamber pillows with high support power
- Size 40x80 cm (only head and neck rest on it, not the shoulders)
More on this topic in our detailed Guide to pillows for side sleepers.
Back sleepers — medium height, good adaptation
Back sleepers need a pillow that supports the neck area without raising the head too much. If the head is too high, the chin is pressed towards the chest — this narrows the airways and strains the neck muscles.
Ideal for back sleepers with neck pain:
- Pillow height 8–12 cm
- Medium-firm filling that adapts to the shape of the head
- Down pillows with 30–60% down content or 3-chamber pillows
- The pillow should be slightly higher in the neck area than in the middle
Stomach sleepers — as flat as possible
Sleeping on your stomach is the most unfavorable position from an orthopedic point of view, because the head has to be turned to the side. A pillow that is too high increases the twisting of the cervical spine and almost inevitably leads to neck problems.
Ideal for stomach sleepers:
- Pillow height maximum 6 cm — or no pillow at all
- Very soft, pliable filling
- Down pillows with a high down content (90%) that can be flattened

Filling materials and their supportive effect
Feather pillows — maximum support
Feathers have a firm, resilient structure. A pillow with 100% feathers yields little and holds the head stably in position. This makes feather pillows the first choice for side sleepers with broad shoulders and people who experience neck pain at night.
The disadvantage: Pure feather pillows feel firmer than down pillows. Those who prefer a soft, cuddly feel will find feather pillows uncomfortable. Therefore, we offer feather pillows in two firmness levels — normal and extra firm. More on this in our Feather Pillow Guide.
3-chamber pillow — support + comfort
The 3-chamber pillow combines the best of both worlds: a firm feather core in the middle provides support, while soft down chambers on the outside offer adaptability and comfort. The result: a pillow that supports the neck but still feels soft.
For neck pain, the 3-chamber principle is particularly valuable because it combines stability and flexibility. The feather core prevents the head from sinking too deep. The down chambers adapt to the shape of the head and distribute pressure evenly.
Down pillows — soft, but little support
The higher the down content, the softer the pillow. A 90% down pillow is luxuriously soft, but offers little support. For side sleepers with neck pain, this is problematic — the head sinks deep, the spine loses its straight alignment.
Down pillows with 30–60% down content (the rest are feathers) are a good compromise: softer than pure feather pillows, but with sufficient support for back sleepers.
From our production: Our 3-chamber pillow is hand-filled in Limburg. The feather core consists of new white feathers according to DIN EN 12131, the outer chambers are filled with Class 1 down. The three-chamber system allows us to independently determine the support power of the core and the softness of the outer layer — an advantage that a single-chamber pillow cannot offer.
3-chamber pillow: Why it helps with neck problems
The 3-chamber principle solves the fundamental dilemma with neck pain: you need both support (so the spine stays straight) and adaptability (so no pressure points arise on the head).
Structure of a 3-chamber pillow:
- Inner chamber (core): Filled with feathers. Provides the basic height and support. The feathers spring back after pressure — the pillow does not lose height even after hours.
- Two outer chambers (top + bottom): Filled with down. Provide a soft, conforming feel. The down adapts to the shape of the head and distributes pressure evenly.
The result: The head rests softly, but the support comes from below through the feather core. Even after a whole night, the pillow maintains its height — unlike pure down pillows, which flatten out over the course of the night.
Detailed information about our pillows can be found in the 40x80 or 80x80 Guide.
40x80 or 80x80: Which size for neck pain?
For neck pain, orthopedists and sleep consultants almost invariably recommend the 40x80 cm format. The reason: On an 80x80 pillow, not only the head and neck, but also the shoulders rest on the pillow. This raises the shoulder, bending the neck — precisely what causes neck pain.
On a 40x80 pillow, only your head and neck rest. The shoulder rests on the mattress and can sink in freely. This is the anatomically correct position for side sleepers.
Exception: If you have an 80x80 pillow and fold it in half, you get an approximately 40x80 pillow with double the height. This can work for side sleepers with very broad shoulders – but it's not a permanent solution.
When You Should Replace Your Pillow
Over time, a pillow loses its supportive power. Down clumps, feathers break, and synthetic fillings compress. The result: the pillow becomes flatter and softer – its support diminishes.
Recommended service life:
- Feather pillows: 5–8 years
- 3-chamber pillows: 5–8 years
- Down pillows (30–60%): 5–7 years
- Down pillows (90%): 3–5 years (loses loft faster)
- Primaloft / Microfiber: 2–4 years
Signs that your pillow needs to be replaced:
- You wake up more often with neck pain than before
- The pillow does not spring back after being compressed
- You fold or stack pillows to get enough height
- The pillow constantly smells musty despite washing
Frequently Asked Questions
Which pillow helps with neck pain?
A pillow that has the right height for your sleeping position and provides sufficient support. For side sleepers, we recommend a feather pillow or a 3-chamber pillow. For back sleepers, a pillow with 30–60% down content. For stomach sleepers, a soft 90% down pillow.
Are neck pillows better than regular pillows?
Not necessarily. Special neck support pillows (made of memory foam or latex) have a pre-formed hollow for the head. This works if you sleep in the same position all night. Those who turn over at night are often better off with a flexible pillow like the 3-chamber pillow, as it adapts to any position.
How high should a pillow be for side sleepers?
10–15 cm, depending on shoulder width and mattress firmness. The wider the shoulders and the firmer the mattress, the higher the pillow must be. When lying on your side, your head should form a straight extension of your spine.
Can a pillow that is too soft cause neck pain?
Yes. A pillow that is too soft offers no support – the head sinks in, the cervical spine kinks. Side sleepers with a pure down pillow (90% down) often experience this problem. The solution: A pillow with a higher feather content or a 3-chamber pillow.
How often should I wash my pillow?
Every 3–4 months. Sweat, skin flakes, and body oils accumulate in the pillow and can cause the filling to clump. Feather pillows and 3-chamber pillows are washable at 60 °C. All BEFA pillows are machine washable and Oeko-Tex Standard 100 certified.
Should I use one or two pillows?
One pillow of the correct height is better than two stacked pillows. Two pillows on top of each other often result in a height that is too high and unstable – the top pillow slips, and the height changes during sleep. It's better to invest in a good pillow of the right height.
Does a special neck pillow help with chronic neck pain?
For chronic neck pain lasting longer than six weeks, you should first seek medical advice. The right pillow can relieve and prevent neck pain, but not cure it. If an orthopedic cause has been ruled out, switching to a more supportive pillow can make a difference.
What pillow size do orthopedists recommend for neck pain?
The majority of orthopedists and sleep consultants recommend the 40x80 cm size for neck problems. On an 80x80 pillow, the shoulders also rest on it, which worsens the position of the cervical spine. In the 40x80 format, only the head and neck rest on the pillow.
