What is the best firm mattress that suits you?

There are quite a lot of people who are worried about what is the best firm mattress? There are many unique features on mattresses, but you may often think that you can’t find a mattress that fits your needs. In the first place, the popularity ranking of mattresses is not very helpful. This is because the mattress you should choose depends on the person who uses it and the scene. No mattress fits everyone and every stage. First of all, this is a central premise. However, a solid understanding of the structure and characteristics of your mattress will increase your chances of successfully choosing the right mattress for you. In this article, I will introduce how to choose a mattress and recommended mattresses by budget from the perspective of the author who worked for a bed maker. The leading roles of the mattress are the following two points.

 The primary role of the mattress

  1. Supports sleeping posture
  2. Disperse body pressure

The first important role of the mattress is to support the sleeping posture. In the ideal sleeping posture, the S-shape of the spine is gentler than when standing. In other words, a suitable mattress condition is to firmly support a sleeping posture in which the spine is stretched more than when standing. The second important role is to distribute the pressure on the body properly. This is the so-called body pressure distribution. “Body pressure” is the pressure exerted on the body from the mattress while sleeping. One of the conditions for the right mattress is moderate pressure dispersibility. And a mattress with high body pressure dispersion is simply a “soft” mattress.

There are four main types of mattresses: The characteristics of each and the advantages and disadvantages of body pressure distribution and turning over are as follows.

Coil system:

Type: Bonnell coil

characteristic: Mattress with connected coils

Advantage: Easy to turn over

Disadvantage: Hard and easy to put a load on the body

Type: Pocket coil

characteristic: Mattress with one coil in the bag

Advantage: Excellent body pressure distribution

Disadvantage: The coil sinks along the line of the body, so it is a little easy to sink

Non-coil system

Type: High resilience mattress

characteristic: Mattresses made of hard materials such as urethane, fiber, and latex

Advantage: Repulsive and easy to turn over

Disadvantage: No

Type: Memory foam mattress

characteristic: Soft mattress

Advantage: Fits the body

Disadvantage: Easy to sink

Which is better, coil, or non-coil?

Mattresses vary in comfort depending on the manufacturer’s technical capabilities and the grade of padding other than the cushion layer, so it cannot be said unconditionally, which is better, coiled or non-coiled. Speaking of force, it uses hard steel wire (steel) rather than the materials used for non-coil (polyurethane, polyethylene, etc.).Coil mattresses tend to be more durable. However, some people are not good at the spring feeling peculiar to spring coils, so it is recommended that those people choose a non-coil type mattress. Besides, spring coils. However, once again, it is not possible to determine the quality of a mattress by evaluating only the cushion layer (coil / non-coil).
