The size of your mattress directly influences the quality of your nights.
Yet, many people are content to choose a mattress identical to their previous one.
Did you know that on average, a mattress lasts 10 to 15 years? In a decade, your lifestyle, sleeping preferences, and even the size of your bedroom can change.
To avoid the discomfort of an ill-fitting mattress, discover in this guide all the available sizes, their advantages and our practical advice for making 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 lack of space.
- General discomfort due to unsuitable dimensions.
- Long-term posture or back problems .
Here are the three main criteria to consider before buying a mattress:
1. Your body shape
A mattress should be long enough for 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, choose a mattress that is 200cm long.
2. Your personal situation
Your lifestyle also influences the choice of your mattress:
- If you sleep alone:
- If you share your bed:
- If you have children or pets:
3. The size of your room
Choosing a mattress that fits the available space is essential. Make sure you follow these guidelines:
- Leave 60 cm around the bed for easy movement.
- A bed that's too large can overcrowd a small bedroom. Instead, opt for a compact mattress, such as a 140 x 200 cm mattress.
