Brief Answer: A pillow for back sleepers should be flat (5–8 cm) and soft to medium-firm. When sleeping on your back, your head is closer to the mattress than when sleeping on your side — a pillow that is too high pushes your chin towards your chest and hyperextends your neck. Down pillows are ideal for back sleepers because they are soft and flat and conform to the shape of the head. 3-chamber pillows with reduced filling also work well.
You sleep on your back, yet you wake up with neck pain. Or you feel pressure at the back of your head in the morning. In many cases, this is due to the pillow: it's too high, too firm, or both.
Back sleepers need a fundamentally different pillow than side sleepers. While side sleepers need height and support, back sleepers need the opposite: less height, more adaptability. As a bedding manufacturer, we explain what matters.

Why back sleepers need a flatter pillow
When lying on your back, the back of your head rests directly on the pillow. The distance between the head and the mattress is significantly smaller than when lying on your side — there is no shoulder cavity that the pillow needs to fill.
A pillow that is too high pushes the head forward, pushing the chin towards the chest. The consequence: The cervical spine is hyperextended, and the neck muscles tense up overnight. In the morning, you feel this as stiffness, headaches, or neck pain.
The Goal: Maintain natural cervical spine curvature
The cervical spine has a natural, slight forward curve (lordosis). A good back sleeper pillow supports this curvature without lifting the head. The pillow fills the hollow space in the neck area — that's all.
- Correct: The head is at the same height as the shoulders, gaze is vertical to the ceiling
- Too high: The chin points to the chest, airways are constricted
- Too low / no pillow: The head tilts backward, the neck is hyperextended
The Aktion Gesunder Rücken e.V. (AGR) confirms: For back sleepers, a flat pillow with 5–8 cm height is optimal, supporting the neck without pushing the head up.
The right pillow height for back sleepers
The optimal pillow height for back sleepers is 5–8 cm. This is significantly less than the 10–15 cm that side sleepers need.
Two factors influence the ideal height:
- Mattress firmness: A soft mattress, into which the body sinks deeper, reduces the necessary pillow compensation. With a firm mattress, you need a little more height.
- Head shape: A flatter back of the head requires less pillow height than a strongly curved one.
How to test the right height
Lie on your back on your mattress without a pillow. Slide a folded towel under your neck and fold it until your head lies straight — without tilting forward or backward. The height of the folded towel corresponds to your ideal pillow height.
From our production: Back sleepers often buy the same pillow as side sleepers — and then wonder why they have neck pain. In our pillow manufacturing, we see the difference every day: A pillow for back sleepers contains about 40% less filling material than the same pillow for side sleepers. Less filling means less height — and that's exactly what back sleepers need.

Which filling for back sleepers?
For back sleepers, different criteria apply than for side sleepers. Instead of maximum support, you need adaptability and a low height.
Down pillows — the first choice for back sleepers
What is a problem for side sleepers is an advantage for back sleepers: Down pillows are soft, flat, and conform to the shape of the head. The down yields under the weight of the head and forms a natural hollow that cradles the back of the head. The neck area is gently supported.
A down pillow with 90% down is the softest and flattest pillow in the range. For back sleepers who prefer a particularly flat lying feeling, it is the optimal choice.
Pillows with 15–30% down — the versatile compromise
If a pure down pillow is too flat for you, pillows with 15–30% down content offer a good middle ground. The higher feather content gives the pillow a little more height and resilience, while the down provides softness. Our 15% down pillow (from €39.90) and 30% down pillow (from €49.90) hit this sweet spot.
Feather pillows and 3-chamber — usually too much for back sleepers
Feather pillows and 3-chamber pillows are designed for side sleepers. Their high support and height are counterproductive for back sleeping — they push the head forward. If you want to use a 3-chamber pillow as a back sleeper, choose the variant with the lowest filling weight.
The right format: 40x80 or 80x80?
Both pillow sizes work for back sleepers:
- 40x80 cm: Only head and neck rest on the pillow. The filling concentrates on a smaller area — the pillow becomes slightly higher. If you move during the night and occasionally turn to your side, 40x80 is the better choice.
- 80x80 cm: More lying surface, the filling spreads wider — the pillow becomes flatter. For pure back sleepers who like a particularly flat pillow, 80x80 cm can even be advantageous.
Manufacturer tips for back sleepers
From 30 years of pillow manufacturing, we know: back sleepers are most often given wrong advice when buying pillows. Here are our five rules:
1. Less is more
The most common problem with back sleepers: too much pillow. If you wake up in the morning with neck tension and sleep on your back, your pillow is most likely too high. Try a flatter pillow — the difference is often immediately noticeable.
2. Softness is not a disadvantage
Many believe a pillow must "support". This is true for side sleepers. Not for back sleepers. When lying on your back, you need adaptability, not support. A soft down pillow that gently cradles the head is physiologically better than a firm pillow that pushes the head up.
3. Pay attention to airways
A pillow that is too high can easily constrict the airways when lying on your back. If you tend to snore, pillow height is an important factor. A flatter pillow can reduce snoring because the airways run straighter.
4. Combination with the right mattress
Back sleepers need a mattress that supports the lower back without pushing up the shoulders. Medium-firm mattresses (H2–H3) are optimal for most back sleepers. On a soft mattress, the body sinks deeper — then you need an even flatter pillow.
5. Combination sleeper? Then choose a compromise
Few people sleep exclusively on their back. If you also sleep on your side, choose a pillow with 15–30% down content in 40x80 cm. It is flat enough for back sleeping and offers enough height for occasional side sleeping.
From our production: When customers ask us "Which pillow for back sleepers?", we almost always recommend our 30% down pillow in 40x80 cm. It's flat enough for back sleeping, soft enough for comfort, and if you do turn to your side at night, it still offers enough support. It's the safest all-rounder for back sleepers.

Frequently asked questions
Which pillow is best for back sleepers?
For back sleepers, a down pillow or a pillow with 15–30% down content is best. It should be flat (5–8 cm), soft, and adaptable. A pillow that is too high or too firm pushes the head forward in the supine position and strains the neck.
How high should a pillow for back sleepers be?
5–8 cm is the ideal height for back sleepers. This is significantly less than the 10–15 cm that side sleepers need. The exact height depends on your mattress firmness and head shape.
Are down pillows good for back sleepers?
Yes, down pillows are the best choice for back sleepers. They are soft, flat, and adapt to the shape of the head. The down forms a natural hollow around the back of the head and gently supports the neck area. What is too soft for side sleepers is just right for back sleepers.
What is the difference between back sleeper and side sleeper pillows?
Back sleepers need a flat (5–8 cm), soft pillow. Side sleepers need a higher (10–15 cm), more supportive pillow. The reason: In the side position, the shoulder creates a large hollow that the pillow must fill. In the back position, this hollow is minimal.
Can I sleep without a pillow as a back sleeper?
Possible, but not optimal. Without a pillow, there is no support in the neck area — the head tips slightly backward. A thin down pillow provides just the right amount of support without pushing the head up.
Does a flat pillow help against snoring?
Often yes. A pillow that is too high can narrow the airways in the back position because the chin is pressed against the chest. A flatter pillow keeps the airways straighter, which can reduce snoring. For severe snoring, however, you should consult a doctor.
Which pillow size for back sleepers: 40x80 or 80x80 cm?
Both work. 80x80 cm can even be advantageous for pure back sleepers because the filling is distributed over a larger area and the pillow becomes flatter. 40x80 cm is the better choice if you also sleep on your side.
How do I care for a down pillow for back sleepers?
Fluff daily, wash at 60 °C every 3–6 months, and tumble dry with tennis balls. Detailed care instructions can be found in our guide Washing a down duvet — the care instructions apply to down pillows as well.
