BMI Index in relation to mattress type

Self-love translates to putting a premium on good sleep. But how do you choose the best mattress if there is more of you to love (that is if you are on the heavy side)? If you are on the heavy side, you need to be extra picky with your mattress. Special attention is necessary to choose the right mattress if your Body Mass Index (BMI) is above the normal range. To compute your BMI, divide your weight in kilograms by the square of your height in metres. You can also speedily check your BMI here with this online calculator.

When you shop for mattresses in shopping centres, you often find that the typical mattress manufacturer usually segregates their mattress collections by using various fancy names. For example, each series would denote their "firmness" ratings by tweaking the internal foam density or perhaps the thickness of the spring coils. So then, consumers have to decide, through touching or sitting, whether a mattress among the many mattress collections will hopefully fit their body type and weight.

A good mattress is essential for all body types, but even more so for those with a high BMI. Conversely, a substandard mattress can spell the difference between high-quality sleep (which translates to high-quality life) and perennial health problems.

The list of health problems that a substandard mattress can worsen is long. You can experience these health issues, among others:

· chronic back pain

· stiffness

· joint and muscle pain

· chronic fatigue

· spinal instability

· spinal disc herniation

A good rubric to select a high-quality mattress that can lessen these health problems includes the following: support, material, size, and density.


The basic rule is if there is more of you to love, you will need more to support you. A firmer mattress can give you the support you need for a good night's sleep. However, adequate support in a mattress depends on firmness and density.

Firmness, however, should not be confused with hardness. A hard mattress will exert more pressure and cause you to sleep with the wrong posture. On the other hand, a firm mattress can prevent aches and pains upon waking because it keeps you in the correct posture all through the entire night. Read: How to Choose the Right Mattress Firmness

Besides firmness, density is also an important component. A denser material means it provides more support per centimetre square. For example, a latex core is much firmer than a memory foam mattress with the same ILD score because it is denser. Therefore, a higher-density mattress is best for a heavier person.

In addition, if you prefer a more billowy and comfortable catch, you can place a topper on your firm mattress. See the available SymFoni® mattress toppers here: Latex Toppers.


This leads to the discussion on the material. An all-natural latex core with a well-formulated density gives the best support and degree of firmness, especially for heavy, high BMI people.

Our SymFoni® all-natural latex mattresses are designed with the ideal latex core density to provide the perfect sweet spot of adequately supporting the sleeper's weight without causing high pressure on their joints. Furthermore, latex cores' natural stability and elasticity allow you to turn with more ease.

The material's breathability is also crucial in choosing the right mattress for this body type. Latex cores have an open cell structure that promotes excellent airflow, therefore, keeping you cool all through the night.

It is natural and healthy that a person would experience a fair amount of turning during sleep. One needs to consider an allowance in choosing a mattress. There should be enough room for movement and allowance for proper stretching per person. For a heavy person, this is essential because there is a higher incidence of stiffness in using a cramped bed size.

Generally, spring mattresses are designed thicker than other mattress types. However, 70%-80% of the thickness comes from the core of spring coils; Synthetic foams, fibres and other materials are then set on top of the spring coils to provide the comfort layer.

A heavier person would generally have a larger body frame or broad shoulders. Therefore, their shoulder and hip joints will receive a lot of upward stress if their mattress has skinny layers of comfort materials because spring coils are too harsh on human flesh. Therefore, an all-natural latex core circumvents this problem because the entire latex core is both the support and comfort layer.

Choosing the right mattress is a big part of self-care. For heavy people, there is more of you to love, but the right options are available. The best practice is to try out the mattress before purchasing, so you will get a feel of the factors above. At BayShop's Sleep Studio, we make bring mattress testing to another level.
