While the duration of sleep was previously emphasized, recently, attention has shifted to the importance of sleep quality. As a result, many unique products have been launched that consider not only pillow height and firmness but also breathability and even the temperature of the pillow's surface.
Since each person has different body types, muscle mass, and sleep concerns, it is essential to find a pillow that suits you.
Key Points for Choosing a Pillow
During sleep, muscles are relaxed, and an unnatural sleeping posture can lead to poor circulation or nerve damage. Therefore, it is necessary to choose a pillow with the right height, firmness, and comfort.
First, let's look at 8 key points for choosing a pillow.
1: Height that does not strain the neck or shoulders
The comfortable height varies depending on body type, so lie down and try it out for fit.
For example, a pillow that is too high for you can cause neck pain or difficulty breathing, while a pillow that is too low can lead to stiff necks and shoulder pain.
For women, slender individuals, and children, a lower pillow of about 3-4cm is recommended. People with larger builds tend to choose higher pillows because the distance between the back of their head and the mattress is often greater, but they should be careful as their airways can easily become blocked during sleep.
For men with solid builds and muscular individuals, a higher pillow of about 5-6cm is recommended. Muscle strength and skeletal structure change with age and lifestyle, so review your pillow regularly.
2: Comfortable and easy-to-care-for materials
Pillow materials are abundant, including polyethylene, urethane, feathers, beads, and buckwheat hulls.
By choosing a material that is not only comfortable and has the preferred level of rebound and firmness, but also easy to care for, you can keep it clean for a long time.
3: Fit and size
Everyone has a different head shape, weight, and body type, so the ideal pillow shape and size will also vary.
There are also specialized pillows, such as those designed to fit the S-curve of the spine or for side sleepers. When it comes to size, it's generally best to choose based on your body type and bed size. Typically, 'M size' is about 43 x 63cm, 'L size' is about 50 x 70cm, 'Semi-long size' is about 43 x 90cm, and 'Long size' is about 43 x 120cm.
4: Functionality such as breathability, elasticity, antibacterial, and deodorizing properties
Many modern pillows come with various features, so choose one that addresses your sleep concerns.
Pillows with excellent breathability or those with evaporative cooling functions that suppress the rise in surface temperature are ideal for people with high body temperatures, those who sweat easily, or those who prefer not to use air conditioning. Consider what features you need, such as high or low rebound elasticity, antibacterial properties, or deodorizing functions.
5: Appropriate price considering replacement frequency
While price doesn't solely determine the quality of a pillow, generally, the price varies depending on the material inside the pillow. Since the lifespan differs by material, consider the replacement frequency when making a decision.
If you want to replace pillows frequently or try various pillows to find one that suits you, a pillow around 5,000 yen is a good option. If you are looking for a functional pillow, you will find a wide variety of suitable options between 5,000 and 10,000 yen. Pillows priced at 10,000 yen or more often focus on advanced features and are recommended for those who know their preferred pillow characteristics or desire a custom-made pillow.
6: Differences in durability
Over long periods of use, pillows can flatten, losing their fit, or become susceptible to dust mites, mold, or odors, necessitating replacement.
There is a significant difference in durability among pillows, so choose according to your preferences and lifestyle, whether you prefer to frequently replace inexpensive pillows or use a more expensive one for a long time.
7: Match your preferred sleeping posture
Generally, for back sleepers, a height that allows the cervical spine to form a gentle S-curve is considered ideal, while for side sleepers, a height that keeps the cervical spine straight is recommended.
Recently, pillows that support side sleeping to reduce snoring have also been released, so choose one based on your preferred sleeping posture and sleep concerns.
8: Ease of maintenance
Regardless of the season, pillows get dirty from sweat, sebum, and drool, so regular cleaning is essential. Whether a pillow can be washed depends on the material of its filling.
Furthermore, if you continue to use a pillow without maintenance, its center may indent from the weight of your head, or the entire pillow may flatten, so be sure to check the maintenance instructions before purchasing.
Types and Characteristics of Pillows
Related to the points discussed so far, the pillow filling is crucial. There are many types of pillow filling materials, so let's introduce their respective characteristics.

Characterized by its unique fluffy feel due to the abundant air it contains, it's recommended for those who prefer a soft sleeping experience. It excels in moisture absorption and release, and boasts excellent resilience. More manufacturers offer feather pillows than down pillows, making it easier to find affordable options. However, feather pillows with quills are slightly firmer than down and may cause the quills to poke through in some products.
Characteristics of Buckwheat Hulls
- Fit: Medium
- Breathability: Good
- Lifespan: 6 months - 1 year
- Firmness: Medium
- Care (Washing): Washable
- Allergies: Buckwheat allergy

- Allergies: Dust mite allergy
- Price range: 2,000 yen - 7,000 yen
Characterized by fibers that are resistant to breakage and produce less lint than natural cotton. It is ideal for those who prefer a soft sleeping experience, as the amount of polyester fill used can create substantial volume and resilience. While it is highly hygienic as it can be washed, its poor moisture absorption and low moisture release mean that dust mites can breed if not properly maintained.
Characteristics of Wool
- Fit: Medium
- Breathability: Medium
- Lifespan: 2-3 years
- Firmness: Medium
- Care (Washing): Fully washable
- Allergies: Dust mite allergy
- Price range: 5,000 yen - 10,000 yen

- Breathability: Poor
- Lifespan: 3-5 years
- Firmness: Soft
- Care (Washing): Fully washable
- Allergies: Almost none
- Price range: 2,000 yen - 3,000 yen
Made with very small expanded polystyrene beads, it offers a smooth feel. The tiny beads are durable and conform flexibly to the neck and shoulders without collapsing. Because their shape can change freely, they may lack stability for larger individuals, potentially causing shoulder stiffness, making them more suitable for slender people.
Characteristics of Hinoki Cypress
- Fit: Low
- Breathability: Good
- Lifespan: 1-2 years (Scent lifespan is about 3 months)
- Firmness: Firm
- Care (Washing): Not fully washable

It offers a stable, firm sleeping experience. Natural hinoki cypress excels in moisture and mold prevention, and disperses heat that accumulates in the head, relieving discomfort. While the pleasant hinoki scent initially envelops you, the scent's lifespan is shorter than the pillow's functional lifespan, lasting only about one month, or at most three months.
