The right thickness can make all the difference
People often choose a mattress topper to improve the comfort of a bed that has become too firm or is starting to show its age. But one question comes up time and again: What thickness should you choose? If it’s too thin, it won’t make a difference. If it’s too thick, it might throw your sleeping surface off balance. Thickness isn’t everything, but it’s a key factor to consider.
1. Why is thickness important?
The thickness of a mattress topper affects:
The feeling of being embraced: the thicker it is, the more it envelops you.
Overall support: A mattress topper that is too soft or too thin may lose its shape.
It adapts to your body type and your existing mattress.
The goal isn't to choose the thickest one possible, but the one best suited to your needs.
2. What level of comfort are you looking for?
First, ask yourself a simple question:
What’s missing from my current mattress?
| Problem | Recommended thickness | Why |
|---|---|---|
| Mattress is too firm | 5 to 8 cm | To soften without losing shape |
| Lack of support | 4 to 6 cm | To reinforce without raising the height |
| Need a soft, cozy place to rest? | 6 to 8 cm | For a cozy, cocooning feel |
| Mattress is too soft or worn out | None | A mattress topper won't be enough |
A mattress topper isn't a miracle solution, but it's a good way to improve or extend the life of a mattress that's still in good condition.
3. What about your body type?
The choice of thickness also depends on your body type and how you sleep.
Body weight affects the pressure exerted on the mattress topper, but it is not the only factor.
| Morphology / Need | Recommendation |
|---|---|
| Lightweight body, slim silhouette | 2 to 4 cm is enough |
| Average or varied silhouette | 4 to 6 cm for good balance |
| Wider frame, sensitive areas (shoulders, hips) | 6 cm or more for effective reception |
But we must also take into account:
Your sleeping position: on your back, on your side, or on your stomach.
What kind of comfort are you looking for: more enveloping or more invigorating?
The firmness of your current mattress: A mattress topper can't make up for everything, but it can subtly adjust the feel.
Did you know? A mattress topper can help relieve back pain.
A well-chosen mattress topper can relieve some of the tension you feel when you wake up, especially if your mattress is too firm.
The ideal choice in this case is a natural latex mattress topper, 5 to 6 cm thick, that conforms to the contours of your body while supporting your spine.

Tip: Check the thickness with a folded blanket
Before you buy, you can try this at home: fold a blanket into several layers and slip it under your fitted sheet.
This gives you an idea of how it will feel depending on the thickness you choose. It’s not perfect, but it helps you visualize the experience.
All of our mattress toppers are made from natural materials, without synthetic foam or chemical treatments.
A mattress topper isn't meant to fix a mattress that's at the end of its life. If it's sagging or too soft, you're better off considering a new mattress. A mattress topper is a comfort enhancer, not a miracle fix.
