Start with your sleep position, then choose a pillow height and firmness that keeps your head and neck comfortably aligned.
Pillows can get confusing fast. Too high or too low can throw your neck out of line, so aim for balanced support.
Key Takeaways
- Your sleep position is the best starting point for choosing pillow height and firmness. Side sleepers generally need more loft, while back and stomach sleepers need less.
- Memory foam, latex, down, and hollowfibre each offer a different balance of support, softness, airflow, and allergy-friendly care.
- Most pillows need replacing once they lose their shape or support, often around the one to two-year mark depending on the material and care.
Beyond height and firmness, how to choose a pillow also comes down to materials, neck comfort, allergies, and how you care for it.
Choosing a Pillow Based on Your Sleep Position
Side, back, and stomach sleepers all create different gaps between the head and mattress. Fill that gap properly and your neck has a much better chance of staying in a neutral position overnight.
Side Sleepers
A higher loft of around 10 to 15 cm usually works best for side sleeping because it fills the gap between the shoulder and head.
Your shoulder width and mattress firmness also matter, so look for enough support to stop your head from dipping down or being pushed upwards.
For extra side-sleeping support, the Ecosa SideSupport Pillow offers adjustable heights from 10 to 15 cm, while the U-Support SideSleeper Pillow wraps around the body for added support through the night.
If this is your usual position, our guide to the best pillow for side sleepers goes deeper into loft, firmness, and materials.
Back Sleepers
A medium-loft pillow is usually a good fit for back sleeping because it supports the head without pushing it too far forwards.
Your neck should rest in its natural curve, with your chin staying comfortably level rather than tilting down towards your chest. If the pillow is too high, your head can be pushed forwards. If it is too low, your neck may not get enough support.
For more detail, see our guide to the best pillow for back sleepers and what to look for in height, firmness, and support.
Stomach Sleepers
The lowest pillow loft usually suits stomach sleeping because the head is already turned to one side for much of the night.
A thick pillow can lift the head further away from the mattress and place extra strain on the neck. A low, soft pillow, or sometimes very little pillow height at all, may feel more comfortable.
Our guide to the flattest pillows for stomach sleepers explains what to look for if you regularly sleep face-down.
Choosing a Pillow for Neck Pain
If you wake with neck pain, start by checking whether your pillow keeps your head and neck comfortably aligned with the rest of your body.
A pillow that is too high or too low can leave your neck bent for hours while you sleep. An adjustable pillow can help here because you can change the height to better suit your sleep position and body shape.
The Ecosa Pillow comes with removable memory foam height pads, so you can add or remove layers until the loft feels right for your neck.

Choosing a Pillow If You Have Allergies
If allergies tend to flare at night, look for a pillow made with hypoallergenic materials and a cover that is easy to wash.
Dust mites are a common allergen found in bedding, so regular washing and dust mite-resistant pillow covers can help reduce exposure. Materials such as memory foam, latex, and washable hollowfibre can also be practical options, depending on your comfort preferences.
For a closer look at materials, care, and suitable options, see our guide to hypoallergenic pillows for allergy sufferers.
Pillow Materials Explained
Memory foam, latex, down, and hollowfibre are common pillow materials, each offering a different balance of support, softness, airflow, and care.
| Pillow Material | Features | Best For |
| Memory foam | Contouring, supportive, and shape-retaining | Sleepers who want close head and neck support |
| Latex | Responsive, springy, breathable, and durable | Hot sleepers and those who prefer a bouncier feel |
| Down | Soft, light, mouldable, and plush | Sleepers who prefer a softer, cushioned pillow |
| Hollowfibre | Lightweight, washable, and usually more affordable | Budget-conscious sleepers and those who prefer easy-care pillows |
Memory Foam
Memory foam pillows moulds around your head and neck for close, contouring support.
It tends to hold its shape well, which can suit sleepers who prefer a steadier feel. Traditional memory foam may retain more heat, although ventilated or cooling designs can help improve airflow.
Ecosa memory foam pillows include:
- Ecosa Pillow for adjustable everyday support
- SideSupport Pillow for side sleepers
- Ecosa Cooling Pillow for sleepers who run warm
- Classic Memory Foam Pillow for a classic contouring feel
- Ecosa Kids Pillow for younger sleepers
- U-Support SideSleeper Pillow for full-body side support
- Cooling Wedge Pillow for elevated upper-body support
- BackRest Pillow for back sleepers who want supportive head and neck alignment
- Cooling Leg Elevation Pillow for raising the legs
- Cooling Pregnancy Pillow for mums who want full-body support
- MemoryFirm Pillow for a firmer memory foam feel
Latex
Latex feels springier than memory foam and responds quickly when you move.
It offers supportive cushioning without the deeper sinking feel of foam, making it a good option if you prefer a more responsive pillow.
The Ecosa Latex Pillow uses natural Dunlop latex with a medium feel and a 12 cm height, making it suitable for all sleep positions. Pinholes through the latex help increase airflow, while the removable cotton cover can be machine washed for easier care.
Down
Down pillows feel soft, light, and easy to shape around your head.
They compress more than foam or latex, so they may suit sleepers who prefer a plush feel rather than firmer support. Some people with allergies may also prefer an alternative filling or a protective pillow cover.
Hollowfibre
Hollowfibre is a lightweight synthetic filling that creates a soft, cushioned feel.
These pillows are often easy to wash and tend to be more affordable than foam, latex, or down. They can lose their shape more quickly, though, so regular fluffing and eventual replacement may be needed.
The Ecosa Loft Pillow and Ecosa Loft European Pillow use recycled polyester hollowfibre for a soft, lofty feel with plenty of fluff, without using feather or down fill.

How Often You Should Wash and Replace Your Pillow
Wash your pillow according to its care label, and replace it once it stops holding its shape or supporting your head properly.
Cleaning needs vary by filling, but these signs can help you tell when it is time for a new pillow:
1. It Feels Flat or Lumpy
Flattened or uneven filling can make it harder for your pillow to support your head and neck consistently.
2. It Does Not Spring Back Into Shape
If your pillow stays compressed after you get up, its filling may have lost some of its structure.
3. You Keep Folding or Bunching It
Constantly reshaping your pillow to get comfortable can be a sign that it is no longer giving you enough height or support.
4. You Wake With Neck or Shoulder Discomfort
Regular morning discomfort may mean your pillow is no longer keeping your head and neck comfortably aligned.
5. It Has Lingering Stains or Odours
If washing no longer freshens it up, replacing the pillow may be the better option.
6. The Filling Has Shifted or Compressed
Uneven filling can leave some areas supportive and others noticeably flat, making it harder to settle into a comfortable position.
