Which is better, a firm or soft mattress?

There are many different tastes for sleeping comfort, so I can’t say which one is better, but the best firm memory foam mattress is better than the futon in terms of structure. Because the mattress is ideal, “This is because “layer structure” is possible. In ergonomics, there is an idea of ​​an “elastic three-layer structure” in making ideal bedding. The concept is that the A layer closest to the body is soft, the B layer in the middle is relatively stiff, and the C layer (cushion layer) at the bottom softly receives the impact. Mattresses made with this concept are “The body feels fluffy and comfortable, but it does not sink too much and supports the sleeping posture.” It provides the ideal sleeping comfort. What kind of firm mattress do you recommend? The big difference between mattresses is in the “cushion layer (C layer)”.The structure of a general mattress is from the top And so on. * The name differs depending on the manufacturer. Coil mattress structure These layers make the mattress more comfortable to sleep on. The life of the mattress is the cushion layer.

The most important thing about a mattress is the “cushion layer”. The cushion supports the body. Mattresses that cannot keep the body will lose their sleeping posture. The right mattress is one that does not quickly settle and has a firm yet smooth, cushioning layer. The difference in the cushion layer Mattresses is divided into various types depending on the cushion layer. Let’s look at the characteristics of two typical types of mattresses, “coil type” and “non- coil type”. Features of coil mattress: The coil mattress’s cushion layer is made of springs such as hardened steel wire. It has a high recovery rate and elastic modulus, and in short, it tends to have high durability. If you want to use it for a long time, we recommend choosing a coil mattress.

However, be aware that coil mattresses that are too cheap tend to have a small number of coils and low quality hardened steel wire and are not durable or comfortable to sleep in. Below, we will introduce three typical types of coil mattresses. 

Typical spring coil

  • Bonnell coil
  • Pocket coil
  • High-density continuous spring

Features of non-coil mattress

The non-coil mattress is a general term for beds whose cushion layer is made of a material other than spring coil. The materials used differ depending on the manufacturer, and there are various variations. Here, we will introduce three typical materials.

Typical non-coil material

  • Urethane foam
  • Fiber (polyethylene, etc.)
  • gel

Difference between low resilience and high resilience

Some mattresses have different strengths, mainly in urethane materials. We are introducing the features of memory foam mattresses and high resilience mattresses.

Memory foam mattress 

A material that slowly returns to its shape when pressed and released. It has high shape stability under load and has a fit that fits perfectly along the body line. This type has the highest body pressure dispersibility. The word “low resilience” is a coined word, and it is correctly called “memory form”. Memory foam means “material with high shock absorption”.

High resilience mattress and High resilience material

A material that returns to its original shape the moment it is pushed and released. The high-resilience foam was developed to improve the disadvantages of low-resilience, such as “difficulty in sleeping” and “difficulty in turning over.” Compared to low repulsion, the fit to the body and the dispersibility of body pressure is soft, but the high repulsive force makes it easier for the body to move. The feature is that it is easy to turn over.
