Custom-made mattresses
The standard size doesn't always fit the space in your room or your individual needs. That's why we offer made-to-measure mattress solutions, guaranteeing personalized comfort without compromising the design of your bed or sommier.
How high should a mattress be?
The height directly influences comfort and durability.
- Between 16 and 20 cm - less recommended for adults.
- From 24 to 30 cm - greater comfort, several layers of materials and greater support.
We suggest mattresses with a minimum height of 20 cm for adults to ensure proper spinal alignment.
Which mattress is best for your back: springs or foam?
This is one of the most common questions. The answer depends on the user's profile:
Mattress with pocket springs:
- Firm support, optimum breathability and independence of movement, offering localized support and reducing movement transfer.
- Ideal for couples and users looking for firmness with comfort.
Foam mattress with viscoelastic:
- It adapts to the body, reduces pressure points and helps align the spine.
