The size of your mattress directly influences the quality of your sleep.
However, many are content to choose a mattress identical to their previous one.
Did you know that on average, a mattress is used for 10 to 15 years? In a decade, your lifestyle, your sleep preferences and even the size of your bedroom can change.
To avoid the discomfort of an ill-suited mattress, discover in this guide all the available sizes, their advantages and our practical advice to make the perfect choice according to your needs.
Why is mattress size so important?
A mattress that is too small, too narrow, or poorly chosen can lead to:
- Restless nights due to a lack of space.
- A general discomfort linked to unsuitable dimensions.
- Long-term posture or back problems .
Here are the three main criteria to consider before buying a mattress:
1. Your body type
A mattress should be long enough to allow you to sleep comfortably. The general rule is to add 10 to 20 cm to your height . For example:
- For a person measuring 1.70m, a 190cm mattress is sufficient.
- If you are 1.80m or taller, opt for a mattress that is 200cm long.
2. Your personal situation
Your lifestyle also influences your choice of mattress:
- If you sleep alone:
- If you share your bed:
- If you have children or pets:
3. The size of your room
It is essential to choose a mattress that fits the available space. Make sure you consider these points:
- Leave 60 cm around the bed for easy movement.
- A bed that's too big can overwhelm a small room. Opt for a compact mattress, such as a 140 x 200 cm one.
