At the end of the day, every couple deserves to have a good night’s sleep in their king bed, and choosing the right mattress firmness is crucial. If you’re wondering what is the best king size mattress for sale, the truth is that there really is no right answer to this question because it’s closely related to your personal comfort, and comfort preferences vary from one person to another. 

What Is Mattress Firmness?

As the name implies, mattress firmness refers to how soft or hard a mattress is. The thing that determines the mattress firmness is the materials used and the mattress’s construction. Generally speaking, a mattress consists of a comfort system that is layered over a support core. Now, this comfort system is made to cushion the pressure points, like your shoulders and hips.

That said, the most important thing you need to know about a thicker comfort system is that it’s made of conforming materials which are designed to give a softer feel. Thinner layers, on the other hand, are made of less malleable materials which are designed to give the firmer mattress feel. Now, what you need to know is that there are all kinds of firmness types available on the market so you can easily find the right king size mattress for sale.

Types of Mattress Firmness

Extra Soft and Soft

As the name implies, both soft and extra soft mattress models sink significantly and are designed to conform to the sleeper’s body. It is said that the extra soft models can conform the most while the soft can conform considerably but not as much. Both of these mattresses rate between 1 – 3 out of 10, which means they are quite soft.

What you need to know about softer king-size mattresses is that they are ideal for side sleepers but not if they are heavier than 60kgs. If heavier people lay on a softer mattress, it could have a bad impact on their back which is not a joke. Another thing you should know about softer mattresses is that they closely contour the body and can trap heat. Because they are made of plush materials, these mattresses can deteriorate in a shorter period of time when compared to some other types of mattresses.

Medium-Soft, Medium and Medium-Firm

Medium-soft mattresses are designed to sink slightly and conform to the body relatively closely while medium mattresses sink less, although they can conform noticeably. Medium-firm mattresses, on the other hand, don’t sink that much and can conform moderately. The offered medium firmness range of a king size mattress for sale is the most preferred choice by people as they have a rate between 4 and 6 out of 10. These mattresses are designed for people of all weight groups and for people who have different sleeping positions. This makes them ideal for partners with different position preferences.

When compared to extra-soft and soft mattresses, the medium-soft and medium-firm don’t conform to the body that much, so they won’t trap as much heat. For these types of mattresses manufacturers also use sturdier materials which explains their longer lifespan.

Firm and Extra-Firm

Firm mattresses are not designed to sink and have minimal conforming while the extra-firm have no sinkage and no conforming. Usually, their firmness can rate between 7 and 10 out of 10. These mattresses are designed for heavier sleepers and those who love sleeping on their stomach. These mattresses also offer proper spinal alignment which is essential.

Given the fact that these mattresses don’t allow any sinkage, they are less likely to trap heat and air can flow freely around the body. This makes them ideal for all those of you who are always hot. Being made of stiffer and more durable materials, firm and extra-firm mattresses are longer lasting.
