The Altum Soft is built from three natural latex layers — a deeper construction than the Aura range. This creates a more progressive cushioning effect that may provide greater pressure relief for side sleepers, pressure-sensitive sleepers, or those who have found standard latex too firm.

All three layers are Natural latex sourced from GOLS certified suppliers. No foam, no synthetic materials.

• Three natural latex layers — deeper pressure relief than the Aura range
• Designed for side sleepers and those who find standard latex too firm
• May help reduce pressure on shoulders, hips, and joints
• Sourced from GOLS certified suppliers throughout — no foam, no synthetic materials

Side sleepers

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

Sensitive sleepers

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

Lighter to medium weight sleepers

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

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

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

Waking up with numbness or tingling is often caused by pressure restricting blood flow. A more cushioned, adaptive surface distributes weight more evenly, helping improve circulation throughout the night.

Restless sleep

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

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

Sleep closer to nature

Create a calm and balanced sleep environment inspired by natural materials.

Organic cotton and wool cover

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

7-zone soft natural latex comfort layer

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.

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.

Natural latex support core

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

Natural Dunlop Latex

Natural latex provides responsive pressure relief and adapts to the body's natural curves.

Organic Cotton and Wool

Breathable natural fibres help regulate temperature and manage moisture.

Coconut Fibre

Coconut fibre adds structural stability and improves ventilation inside the mattress.

Naturalist firmness configurations

Soft

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.

Recommended for:

Side sleepers
Combination sleepers
Light to medium body weight
Pressure-sensitive sleepers

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.

Recommended for:

Back sleepers
Combination sleepers
Medium body weight
Sleepers who want both comfort and support

Learn more

Firm

Higher resistance with reduced compression.

This setup increases structural support and limits surface deformation.

Recommended for:

Back sleepers
Stomach sleepers
Higher body weight
Sleepers requiring reduced sink

Each side operates independently within the same structure.

Recommended for:

Couples with different preferences
Partners with different body weights
Shared beds requiring separate configurations

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

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

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

Low profile that fits your space

The slimmer design takes up less visual and physical space. Ideal for smaller rooms, minimalist setups, or lower bed frames.

Natural temperature regulation

Breathable natural materials help maintain a comfortable sleep temperature throughout the night.

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

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

Always fresh and breathable

The internal structure allows continuous airflow, so the mattress stays light, airy, and comfortable throughout the night.

Modular delivery system

Delivered in manageable boxes for easier transport and setup.

Easier to transport

The Naturalist mattress is delivered in several manageable boxes instead of one large package, making transportation much easier.

Easier to carry upstairs

Smaller boxes are easier to carry through narrow staircases, elevators and hallways.

Simple assembly

The mattress layers are assembled easily at home, creating the full mattress structure in just a few steps.

Assembly instructions are included with every mattress.
