Naturaliste Altum — Doux

Naturaliste Altum — Doux

L'Altum Soft est composé de trois couches de latex naturel, une construction plus profonde que la gamme Aura. Cela crée un effet d'amortissement plus progressif qui peut offrir un meilleur soulagement de la pression pour les personnes qui dorment sur le côté, les personnes sensibles à la pression ou celles qui ont trouvé le latex standard trop ferme.

Les trois couches sont en latex naturel provenant de fournisseurs certifiés GOLS. Pas de mousse, pas de matériaux synthétiques.

Is this soft latex mattress right for your sleep style and body type

Designed for sleepers who need deeper pressure relief, softer cushioning, and a more enveloping sleep surface.

Dormeurs sur le côté

Dormeurs sur le côté

Soft, deeper comfort reduces pressure on shoulders and hips, allowing your body to sink in more gradually and relax without tension points.

Sensitive sleepers

Sensitive sleepers

A more cushioned, adaptive surface gently responds to your body, helping reduce numbness, discomfort, and nighttime pressure buildup.

Dormeurs légers à moyens

Dormeurs légers à moyens

A deeper soft construction allows proper contouring without pushing the body upward, supporting natural alignment in a more relaxed position.

Sleepers who prefer a soft feel

Sleepers who prefer a soft feel

Creates a deeper, more enveloping sensation while maintaining underlying support — ideal for those who want maximum comfort without losing stability.

If your mattress creates pressure, your sleep can suffer

The Full Latex Soft construction adapts to your body, reduces pressure points, and supports natural circulation - helping you sleep deeper and wake up without discomfort.

Pressure on shoulders & hips

Pressure on shoulders & hips

Side sleepers often experience pressure buildup in the shoulders and hips. A deeper, softer latex surface allows the body to sink in more gradually, reducing tension and helping muscles fully relax.

Numbness & poor circulation

Numbness & poor circulation

Se réveiller avec des engourdissements ou des picotements est souvent causé par une pression qui restreint le flux sanguin. Une surface plus rembourrée et adaptative répartit le poids de manière plus uniforme, aidant à améliorer la circulation tout au long de la nuit.

Sommeil agité

Sommeil agité

Constant tossing and turning can be a sign of surface discomfort. A deeper comfort profile reduces pressure points and micro-adjustments, helping your body settle into longer, uninterrupted sleep.

Overheating

Overheating

Natural latex remains breathable even in softer constructions. Open-cell structure allows airflow, helping regulate temperature and prevent heat buildup during sleep.

Inside the Naturalist Full Latex Plus Mattress

Une construction en latex à trois couches conçue pour un confort plus profond, un soutien adaptatif et une respirabilité naturelle — sans ressorts, sans mousse et sans remplissages synthétiques.

1

Housse en coton biologique et en laine

Breathable natural fabric that regulates temperature, manages moisture, and creates a clean, comfortable sleep surface.

2

Couche de confort en latex naturel doux à 7 zones

A pressure-relieving top layer designed to gently adapt to your body’s natural curves, allowing deeper relaxation and reducing tension in shoulders, hips, and joints.

3

Cushioned soft latex layer

An additional soft latex layer that deepens the comfort profile and creates a more welcoming, cushioned feel - adding a subtle sense of softness and luxury to the sleep surface.

4

Noyau de soutien en latex naturel

A firm latex base layer that stabilizes the structure from below, preventing excessive sinking and keeping the spine properly aligned.

Certifications

GOLS certified latex

GOLS certified latex

Ensures the latex is made from certified organic raw materials and meets strict environmental and social standards.

GOTS certified textiles

GOTS certified textiles

Covers organic cotton and wool, ensuring responsible production, safe processing, and traceability.

Dunlop latex

Le latex Dunlop est un matériau naturel fabriqué à partir de la sève des hévéas, traité selon une méthode traditionnelle de moulage et de vulcanisation.

Lors de la production, le latex est versé dans un moule et se stabilise doucement, créant une structure légèrement plus dense et plus stable. Cela donne un matériau plus soutenant et durable par rapport à d'autres types de latex.

Il a une sensation naturellement élastique, lui permettant de réagir aux mouvements du corps tout en maintenant un soutien constant tout au long de la nuit.

Latex firmness

Soft latex (~65 kg/m³)
Provides higher elasticity and contouring, allowing the body to sink slightly into the surface. Helps reduce pressure on shoulders and hips.

Firm latex (~85 kg/m³)
Offers greater resistance and stability, supporting the body more firmly and helping maintain proper spinal alignment.

Naturalist firmness configurations

This mattress is currently configured as Soft.

Doux

Current configuration

Gentler pressure relief with deeper compression under load.

This setup allows the body to sink in more easily and creates a softer, more adaptive feel.

Medium

A balanced feel created by placing the firmer latex layer on top and the softer layer underneath.

This setup provides more stable support with a subtle underlying softness.

Learn more

Firm

Higher resistance with reduced compression.

This setup increases structural support and limits surface deformation.

En savoir plus

Dual Comfort

Different firmness levels on each side of the mattress.

Each side operates independently within the same structure.

En savoir plus

Three firmness options in one mattress

By rearranging the order of the latex layers, you can adjust the feel from Soft to Medium to Firm - all in one mattress.

Adjust comfort by rearranging the latex layers

The Full Latex Plus mattress is built with three interchangeable latex layers that can be easily rearranged at home.

With the softest layers on top, the mattress feels deeply cushioned and pressure-relieving - ideal for a softer, more enveloping feel.

By changing the layer order, you can create a more balanced feel with moderate cushioning and stronger support.

Place the firmer layer on top, and the mattress becomes more supportive and structured - ideal if you prefer a firmer sleep surface.

This gives you three distinct comfort options in one mattress, allowing you to adapt it over time without needing to replace it.

More usable space, without compromise

Sleep, move, and use your bed freely — with support that stays consistent across the entire surface.

Sleep all the way to the edge

Sleep all the way to the edge

No need to avoid the sides. The mattress feels just as supportive at the edge as it does in the center.

More space when sharing the bed

More space when sharing the bed

Stable support helps reduce rolling toward the middle. Both sleepers can comfortably use their full side of the mattress.

Régulation naturelle de la température

Heat doesn’t build up

Heat doesn’t build up

Air moves freely through the mattress instead of being trapped around your body, helping you maintain a more comfortable sleep temperature.

Less humidity during the night

Less humidity during the night

Natural fibres absorb and release moisture, reducing that warm, damp feeling and keeping your sleep surface more balanced.

Always fresh and breathable
