How to choose a mattress well

For those who never want to regret!

“All mattresses are about the same.”

I thought so too. From the front to the back of this industry.

To be honest, there are various “price” and “quality”.

And, regardless of the price, there are some that can be used to sleep well and some that hurt the back.

And the problem is that the quality (specifications) is difficult to understand.

What’s worse , from 2018 , changes in industry rules have made it unnecessary to disclose the specifications.

Choosing a mattress has become really difficult.

But don’t worry.

Today, as a way to choose a mattress that you will not regret

5 points to check if the mattress is comfortable to use

Features of 6 types of mattresses
I will introduce comprehensively about.

It’s been a long time with lots of technical explanations, but if you read it to the end, you should be able to start choosing a mattress with confidence.

The answer to choosing a mattress

1. Five points to check if the mattress can be used comfortably

First of all, let’s check if the following 5 points are suitable for you.

Hardness / softness (≒ body pressure dispersibility)
Elasticity (≒ comfortable support)
Thickness / height
Quality (urethane density / coil quality) (≒ durability)
Width size
I will explain specifically what it means.

1-1. Appropriate mattress hardness

There is no perfect hardness / soft mattress for everyone.

However, the mattress is of the right hardness / softness for you if it meets the following points:

You can sleep in a proper sleeping posture
Easy to turn over
Hardness / softness of your choice
There is no feeling of pressure on the waist etc.
Ideal sleeping posture
Proper sleeping posture
It is no exaggeration to say that hardness is the most important thing.

Slightly too hard: feel pressure / get tired of sleeping
Too hard: hurt your lower back and back
Too soft: Poor sleeping posture / Tired of sleeping / Hurts lower back and back
This is because the lack of hardness can hurt your body, make you tired of sleeping, and easily reduce the quality of your sleep.

Comfortable sleep that is neither too hard nor too soft is important
Comfortable sleep that is neither too hard nor too soft is important
In addition, let’s think about “body shape” and “familiar sleeping comfort” together.

Body shape: Hard for fat people, soft for thin people
Familiarity: Be careful if you suddenly make a big change from the comfort you are used to
In other words, a fat person who has been sleeping on a memory foam mattress for 5 years may feel uncomfortable and unsatisfied with the comfort of sleeping if he suddenly makes it stiff according to the textbook.

Therefore, it is recommended that you take some time to make it as hard as normal.

mattress
There are many points to consider just for hardness.

For that reason, we recommend that you take a good night’s sleep before purchasing a mattress.

Once you buy a mattress, you will have a long relationship.

Try sleeping hard, soft, expensive, cheap, etc. to find the “hardness that suits you”.

The following five points can be summarized as a summary of the points for trial sleeping on mattresses.

Do you like the first impression when you go to bed?
Try sleeping for 5 minutes to see if the hardness really matches
Try to turn over easily
You don’t have to worry too much about the texture of the side fabric
Do you mind rolling (if used by two or more people)?

1-2. Is the elasticity (repulsive elasticity) of the mattress sufficient?

Rebound resilience is an important factor in sleeping comfortably.

The role of elasticity is to support the body that is properly submerged in the mattress so that it does not collapse in the correct sleeping posture, and to promote a smooth turn over.

For spring mattresses, the elasticity depends on the urethane foam, latex, and cotton material used for the filling.

When it comes to non-coil mattresses, the impact resilience of urethane and latex directly affects sleeping comfort.

If you take a test sleep while checking how much quality the material is used, you should be able to feel the difference.

1-3. Appropriate mattress thickness

Mattresses vary in thickness.

Moreover, the difference in thickness is so small that you may be wondering which one is right for you.

Although it is a little rough, if the thickness of the mattress is classified into 7 types, the purpose of use suitable for each is as follows.

indicator-of-mattress-height
To summarize the points briefly, if you use a mattress on the floor, it is safe to have a thickness of 7 cm or more.

If it is less than 7 cm, it may feel bottomed and hurt your lower back.We also recommend that the spring mattress has a thickness of 20 cm or more.

If the thickness is less than 20 cm, there is too little cushioning material such as urethane foam, and the hardness of the spring may be felt on the waist and back, which may be unpleasant.

Poor quality spring mattresses often have too little padding
Poor quality spring mattresses often have too little padding
On the other hand, high-resilience mattresses and latex mattresses with a thickness of 20 cm or more are a little wasteful.

Even if it is not that thick, it is comfortable to sleep in, but it is sometimes thickened because it is “thick” = “gorgeous and luxurious”.

Similarly, spring mattresses with a thickness of 35 cm or more are often useless.

Some even spring mattresses have too much urethane foam or wadding to feel the spring elasticity.

1-4. Appropriate mattress material quality

It would be very disappointing if the mattress I bought thinking that it would be usable for about 10 years would be worn out in 5 years.

You can check for yourself if the mattress’s service life is as you expected.

bonnel-coil-spring
Various quality of coil wire
Check “Urethane density” and “Coil spring quality label”.

The relationship between urethane density and durability is as follows.

I think it’s easy to imagine that low-density squishy things are easy to settle.

Next is the quality of the coil spring wire.

The contents of the quality display are illustrated below.

  • How to read the quality display of coil springs
  • How to read the quality display of coil springs
  • The guideline for the useful life is as follows.

Piano wire is suitable for use for more than 10 years.
The wire is a hard steel wire and the carbon content of (2) is:
60 units are mostly inexpensive and have a useful life of about 3 to 5 years.
Most of the products in the early 70s have a useful life of around 5 to 8 years.
Those in the latter half of 70 units are expected to be used for a longer period of time.
In addition, quenching of wire rods is also an important guideline.

However, please be aware that the useful life of the mattress is greatly affected by the usage environment (eg, constitution and presence / absence of bed pad).

note! : Unfortunately, the quality labeling method for spring mattresses has been revised since March 30, 2017, and the labeling content has been greatly simplified.
In the future, it will be displayed like this, so it is no longer possible to know the number, size, material type, quality, etc. of springs by looking at the product label. However, manufacturers and retailers continue to buy and sell with reference to the above specs, so if you ask the mattress wire and quality at the store, they will tell you. It is a knowledge that can be used to select excellent products, so even if it is not stated on the quality label, it is good to know.

  • Quality of side fabric and filling
    This is a point of judgment.

This is because no matter how good the material of the side fabric is, the presence of bed sheets and pads will be diminished.

It is good to elaborate the material of the side fabric
Sticking to the material of the side fabric may be secondary
For example, it is natural that wool wadding is better hygroscopic than polyester wadding as a cushioning material.
However, when it comes to laying a bed pad on a mattress, it really makes a difference.
Therefore, when choosing a mattress and bedding,
Hardness, elasticity, thickness, quality of parts
Bed sheets, covers, pads
Mattress side fabric
It is good to stick to the priority.

1-5. What is the appropriate mattress width for you?

Consider the mattress size based on your body size, number of people, and the size of your roll.
The person in the illustration below is assumed to be 170 cm tall and weigh 60 kg.

Mattress size 1
Mattress size 1
Mattress size 2
Mattress size 2
Please be careful that double size is not for two people.

Please note that using a double size mattress for two people will make it feel quite narrow.

2. Deepen your knowledge of mattresses

In the first place, for bedding

Bed mattress and mattress
There are differents types, so it’s also important to consider whether your bed mattress and mattress are right for you.

In addition, the comfort of a mattress differs depending on the material (type), and whether or not the items around the mattress can be used correctly is also an important point when choosing a mattress.

Learn more about mattresses so that you can choose a mattress well.

2-1. [Bed mattress vs mattress vs futon] Know the difference

There are three types of bedding.

Double-check whether it’s a mattress, a bed mattress, or a mattress that suits your lifestyle.

Bed mattress
A mattress made of bonnel coil, pocket coil, urethane, latex material, etc. that has a thickness of about 16 cm or more and is used together with the bed frame.
Mattress
A mattress made of materials such as low-resilience / high-resilience urethane and latex that can be used on the bed but can also be placed directly on the flooring.
Mattress A mattress
that is used by placing it directly on the floor, such as cotton, wool, or polyester wadding.

Based on the advantages and disadvantages, we can recommend it to the following people.

Bed mattress: Recommended for those who are not planning to move for the time being and are looking for a spring mattress that can be used for a long period of 10 years or more with a budget of 100,000 yen or more.
Mattress: Recommended for those who are looking for a mattress that can be used for a medium period of 6 to 7 years for 40,000 to 50,000 yen.
Mattress: Recommended for those who are looking for something that can be easily handled by laying it on the floor.
Details will be left to the following page, but not only the cost but also the contents of daily care will change, so be sure to choose bedding that suits your lifestyle.

2-2. How to choose items around the mattress

Sheets and pads are complicated, aren’t they?

Have you ever wondered, “Do you need all this?”

In conclusion, one is absolutely necessary.

But not all are needed.

What you need above and below the mattress
What you need above and below the mattress
You can use what you need according to your constitution and lifestyle.

The simple explanation is as follows.

Minimal requirements: [Mattress → Mattress pad or mattress protector]
I want to be particular about the touch: [Mattress → Mattress pad or mattress protector → Bed sheets]
I want to make my sleep comfortable: [Mattress → Bed pad or mattress topper → Bed pad or bed sheet]
High humidity in the bedroom: [Dehumidifying sheet → Mattress → Any of the above]
Only the recommended combinations are introduced here, but if you want to dig deeper into the reason behind this, please refer to the following page.

2-3. Know the characteristics of 6 types of typical mattresses

If it’s a mattress / bed mattress that suits you rather than a mattress, you’ll have to choose from the following six mattresses:

It’s a little rough, but if you evaluate each feature on the four axes of body pressure dispersibility (fitting), support (maintaining sleeping posture), breathability (stuffiness), and ease of maintenance. It will be as follows.

This is an average rating for each type. If the material is good, ◯ will be ◎, and depending on the processing method, △ will be ◯.

On the contrary, ◎ may become △ due to bad material.

Next, I will explain the features of each mattress individually (the series that compares mattresses of the same type with low quality and high quality mattresses was popular, so I will reproduce it in the same way here). ..

Regarding the question of which one is recommended after all, the high-resilience urethane mattress is recommended because of its overall performance in terms of comfort, usability, and price. If you prefer a thick spring mattress for good looks, then a pocket coil mattress is recommended.

① High resilience urethane mattress

The low-priced ones are not so uncomfortable to sleep, and they have a feeling of use such as “Well, don’t sleep”. If you use a cotton pad, you won’t feel stuffy, so you can only use it for a couple of years, but it’s cheap and reasonable performance.
The high-quality urethane surface is processed into an uneven or wavy shape, and the body pressure dispersibility is at a sufficiently good level to prevent stuffiness. Furthermore, the really good one is elastic and flexibly supports the body. ..
Considering performance and price, cost performance is generally good. However, since it can be washed with water, it can be easily removed, but it cannot be cleaned, so be careful not to get it dirty. Please refer to the following page for details.

② Memory foam urethane mattress

Low-quality products have low durability, so if you use them for about a year, you will have a bad sleeping posture that will cause your body to sink too much. This is why it is said that “low-resilience urethane mattress = low back pain”.
On the other hand, high-quality products are well-made, so it is easy for the body to sink in and maintain a good sleeping posture. It’s a little hard to turn over, but this is a judgment of whether it suits your taste and constitution.
Be sure to use the pad because it is not breathable and easily stuffy, and it cannot be washed or cleaned. We recommend a thin one that does not kill the unique sleeping comfort of memory foam. Please refer to the following page for details.

③ Bonnell coil mattress

Poor quality Bonnell coil mattresses give you the comfort of a cheap hotel. The durability of the padding on the coil is poor, and after about a year of using it, it becomes quite hard and may hurt your lower back.
High quality products provide a good night’s sleep, and the better the padding, the better the pressure distribution. The urethane mattress on the surface has good ventilation inside, so it is also recommended for those who are concerned about the humidity in the bedroom.

④ Pocket coil mattress

For low-priced ones, the fluffy pitching of the coil is a concern. It’s good to start using, but be aware that when you start to settle down, your lower back tends to fall and your sleeping posture gets worse.

High-quality items that exceed 100,000 are high-quality stuffing and have good body pressure dispersion, and high-quality and durable coil springs support the body parts according to the weight, so it is very comfortable to sleep.
Good ones are quite expensive, but they can be cleaned and are suitable for long-term use of 10 years or more. Please refer to the following page for details.

⑤ Latex mattress

Low quality ones are soft and elastic, but the bounce is too strong and the shaking is worrisome. Also, if the durability is not good, you need to be careful because your lower back will fall and your sleeping posture will worsen.

High quality products have high elasticity and support according to the weight of the body while the body sinks moderately. It is easy to turn over and is comfortable to sleep in.

It has the advantage of being antibacterial and making it difficult for mites to grow, but like low-resilience urethane, it feels stuffy if air conditioning is not controlled, and it cannot be washed / cleaned with water, so it is necessary to take proper measures against dirt. Also, those with rubber allergies are strictly prohibited from using. Please refer to the following page for details.

⑥ High resilience fiber mattress

Low-quality products are hard and do not disperse body pressure well (especially for lean people), and it is easy to feel discomfort on the back. However, even if it is of high quality, it is still comfortable to sleep on the surface, so it is recommended that you take a good test sleep.

If you are dissatisfied with the dispersibility of body pressure, try supplementing it with a mattress topper or a thick bed pad.

It has good breathability, so it is a candidate for those who value a cool sleep above all in the heat. Also, even if it gets dirty, it can be washed cleanly in the shower, and mites rarely occur, so I think it will be a candidate for those who place importance on hygiene.

2-4. Understand the types and characteristics of beds

Unless you put the mattress directly on the flooring, you might consider buying a bed frame.

If you know what kind of beds exist, you will not regret it later, saying, “Oh! There was such a bed!”
These are the types of bed frame structures.

The atmosphere changes greatly depending on whether it is wood-like or leather / upholstered, so please use it as a reference. This page “10 types of bed frames! Please refer to the details of each bed frame in “How to choose by focusing on the function” .

3. Checklist for choosing a mattress you won’t regret

When you buy a mattress, you can choose the right mattress by taking your lifestyle and environment into consideration.

Q1: Do you
have a plan to move ? If you plan to move in the future, we recommend a light and compact mattress such as a tri-fold type because it is easy. Spring mattresses and latex mattresses are bulky and heavy. It can also increase the cost of moving.
Q2: Do you plan to have a baby?
We do not recommend purchasing a bed. Considering sleeping with your baby, we recommend that you sleep with a mattress on the floor.
Q3: If you are uncertain about the softness or normal hardness, it is safe to choose the normal hardness.
You can buy more toppers to make your sleep softer, but vice versa is a bit unreasonable.
Q4: If you sleep mainly sideways, we recommend a little softer if you can sleep mainly sideways. Make sure to check when you go to bed to see if it fits in your waist and your body pressure is too concentrated on your lower back.
Q5: Should I buy a pad?
It is recommended to use it together because it can make the mattress last longer by preventing night sweats from getting dirty and dripping due to humidity. With a pad, there is almost no need for bed sheets. For more information, see this page “Do you need sheets if you have a pad? Please refer to “3 unnecessary cases” .
Q6: Should I be particular about the side fabric?
Most of the high-quality side fabrics are made of natural materials, but they do not have to be evaluated when choosing a mattress. We recommend sticking to the fabric of the sheets and padding.
Q7: If you use it as a couple, let’s try sleeping together and check if you are worried about rolling. Also, if it is queen size or larger, you can sleep comfortably, so it is recommended. Or you can sleep with two single sizes side by side. There is an advantage that you can use mattresses, mattresses, and sheets that you like.
Q8: If your child uses bedwetting, consider the possibility of vomiting due to illness, so use a mattress that can be washed with water or use a mattress protector together.
Also, considering the fall, we recommend that you place it on the floor.
Q9: If the bedroom is easy to get damp If the bedroom is easy to get damp, focus on good ventilation and easy maintenance.
It is even better if you can use a dehumidifying sheet together. For more information on the dehumidifying sheet, see this page “Damping beds and futons! Please refer to “Illustration of how to use the dehumidifying sheet” .
Q10: If you are particular about air conditioning, if you do not use a cooler even on tropical nights in summer, memory foam mattresses and latex mattresses are not recommended as they tend to get stuffy.
Q11: If you buy an overseas brand, make sure that it is the size of your contry specifications. Also, please be aware that some of the low-priced mattresses made overseas that are on sale online have poor quality control (from the level of requirements).

We hope that the content of the introduction will help you choose your mattress.
