Sleeping on a mattress that's appropriate for your weight promotes restful sleep.
When choosing which mattress to buy, there are many factors to consider, and weight is one of them. In fact, each body type corresponds to a specific type of mattress. However, the choice can be more complicated if you sleep with a partner. Here are a few tips on how to choose a mattress based on your preferences and needs, including your weight.
Choose the firmness level based on your BMI
As a general rule, the heavier you are, the firmer the mattress you sleep on should be to properly support your body. BMI, or body mass index, is a standard measure that provides accurate information about your body weight and offers guidance on choosing a mattress based on your weight. It is calculated by dividing your weight by the square of your height. A BMI is considered normal if it falls between 18.5 and 25 kg/m². So, if you have a normal BMI, opt for a medium-firm mattress. Suitable for all body types, a natural latex mattress will be perfect because it provides ideal support and optimal comfort.
A. For petite people
With a BMI below 18.5 kg/m², a person weighing between 50 and 70 kg may be considered petite. A memory foam mattress that offers a soft and cozy feel can therefore be a good option. However, it has the drawback of not being breathable and containing too many toxic substances. The best option, then, is to choose a mattress free of substances harmful to health, such as a natural latex mattress. Made from rubber tree sap, it is naturally dust-mite-resistant, antibacterial, and hypoallergenic.
B. For people who are overweight
If you have a high BMI, it’s best to choose a firm mattress, especially in the pelvic, hip, and buttock areas. With up to 7 support zones and a density of up to 95 kg/m³, natural latex mattresses are perfectly suited for heavier individuals (80 to 110 kg). Furthermore, to balance out the mattress’s density, make sure the padding is well-padded. In this regard, the natural latex mattress scores another point! Made from a single block of latex, it offers a plush feel while remaining firm.
Density: An Important Factor in Choosing a Mattress Based on Your Weight
It’s essential to consider the density of the mattress when deciding how to choose a mattress based on your weight. Mattress density and firmness are two different factors that both deserve consideration. For example, with foam mattresses, firmness and density aren’t necessarily proportional because of the many components they may contain. In other words, even with a high density, a foam mattress doesn’t necessarily provide the support you need. On the other hand, a natural latex mattress contains no components other than latex that could throw off your calculations. So, keep in mind that the density of a natural latex mattress typically ranges from 65 to 85 kg/m³. If you’d like more support, however, you can opt for a higher density mattress designed for heavier individuals. Just be sure not to exceed 90 kg/m³, because above that density, the mattress will be too firm and may become uncomfortable.
As for the thickness of a natural latex mattress, it generally ranges from 15 to 18 cm. Keep in mind that the thicker your mattress is, the less you’ll feel the “sagging” effect, especially when you’re sitting. For more details, see the article “Density of a Latex Mattress."
How do you choose a mattress based on your weight and your partner's weight?
If you share your mattress with someone else, you need to take into account both of your body types, which may differ. You should therefore choose your mattress based on your weight and your partner’s weight. If there isn’t a significant weight difference between you, choosing a mattress shouldn’t be too difficult. If you’re both on the lighter side, opt for a soft mattress. On the other hand, a firm mattress designed for heavier individuals is recommended if you’re on the heavier side. Always refer to your body mass index (BMI). If there’s a significant weight difference between you and your sleeping partner, consider choosing a mattress with independent support zones. While pocket-spring mattresses are known for providing excellent sleep independence, keep in mind that natural latex mattresses will also prevent you from being disturbed by your partner’s movements while you sleep. You can also simply opt for separate mattresses. The bed can then be made up of two mattresses with different densities.
