When choosing a mattress, we usually look at whether it is hard or soft, whether the cover is cute, what it is made of. But one point is almost always missed – how much weight it can withstand.
If the mattress is not designed for your load, it will not live long. It will quickly sag, skew and, instead of support, begin to harm your health. A couple of years later – the purchase of a new mattress and constant pain in the lower back.
So it is better to figure out in advance: what the load of the mattress means, how to understand whether it will suit you in weight and what is important to consider so that it is comfortable to sleep on it not only in the first month.
What Does The Load On The Mattress Mean?
This is the maximum permissible weight per bed. If the mattress is not designed for such a load, it loses elasticity, sags and ceases to support the back.
What Does The Permissible Load Depend On?
The permissible load depends on the design of the mattress – what and how it is made:
filler: dense materials hold weight better;
Springs: Independent units can withstand more than legacy dependent systems;
Assembly and materials: the more secure the layers and fasteners, the longer the mattress retains its shape.
In springless models, the weight is distributed over the entire surface. In spring springs, each spring works separately, adjusting to the curves of the body.
In springless mattresses, the load is distributed over the entire surface.
In spring mattresses, the load is taken on by individual springs, adapting to the body.

How To Choose The Right One
Focus on the load margin – at least + 20% to your weight.
If you weigh 90 kg, a mattress designed for 110-120 kg or more will do. This will extend the service life and maintain the comfort of sleep.
How The Load On The Mattress Is Calculated
Your weight is only part of the equation. In order for the mattress to last a long time and not lose its shape, you need to take into account a few more important factors:
Filler And Stiffness
Dense materials such as natural latex, coconut coir or high-density foams hold weight better. They are designed for loads from 110 to 150 kg.
Natural latex is a dense filler that can withstand up to 150 kg without deformation.
Adaptive materials (for example, memory foam) are squeezed harder, especially under increased load. Their maximum: 90-110 kg per bed.
Adaptive memory foam precisely adjusts to the body and gives cozy comfort for a weight of up to 110 kg.
Combined Options: Latex With Coconut, Foam With Latex
Such mattresses combine soft and hard layers, which allows you to withstand loads of up to 140-160 kg and distribute the weight more evenly. This is a good option if you want to get comfort and durability at the same time.
Mattress Height
Tall models (from 20 cm and above) are stronger and more resistant to deformation. Low-profile ones (14-18 cm) sag faster – especially under heavy weight.
The higher the mattress, the more reliable the support and protection against deformation – especially under heavy loads.
Support Areas
If the mattress has firmness zoning (for example, 3, 5 or 9 zones), it distributes pressure better over the entire surface. This means fewer overload points and a longer service life.
How To Choose A Mattress By Weight And Firmness
The general rule is simple: the greater the weight, the firmer the mattress should be.
A soft model will bend too much under heavy load, and the back will no longer receive the necessary support. This can lead to constant tension in the lower back. A mattress that is too hard is also not an option, as it does not follow the shape of the body, it can put pressure on the shoulders, hips or lower back.
Below are recommendations on how to choose a mattress in terms of firmness and load, depending on the weight of a person’s body.
Best Mattresses For Heavy Weight
If your weight exceeds 100 kg, choosing a mattress becomes a matter of not only comfort, but also health care. Conventional models that are not designed for heavy loads can quickly lose their shape, lose their orthopedic properties and even cause back pain. Therefore, it is important to choose exactly the mattress that will withstand your load and give you quality sleep.
