Firm natural latex and horsehair — designed for sleepers who need support and breathability
The Heritage Firm combines firm natural latex — structured to minimise surface compression — with a natural horsehair layer designed to improve airflow and moisture management. Built for back and stomach sleepers who also tend to run warm.
The most durable configuration in the Naturalist range. Made with materials from GOLS and GOTS certified suppliers — tested lifespan of 25+ years.

Designed for sleepers who need maximum support, better alignment, and a cooler, more stable sleep environment.
Provides firm support to keep the spine aligned and prevent lower back strain. Helps maintain a stable, healthy sleeping position throughout the night.
A firm surface keeps the hips elevated and prevents excessive sinking. Helps maintain proper alignment and a more stable sleep position.
A deeper support system maintains its shape under higher weight. Reduces compression and ensures consistent support over time.
Improved airflow and moisture control help release heat and reduce discomfort. Creates a cooler, drier sleep environment throughout the night.
The multi-layer firm latex construction is designed to eliminate instability and deep compression — improving alignment, reducing strain, and helping maintain a cooler, more controlled sleep environment.
Sleeping on a surface that lacks proper support can strain your lower back. Firm latex layers keep your body elevated and aligned, reducing pressure and helping maintain a healthier spinal position.
Excessive sinking can reduce stability and affect how your body is supported. The multi-layer firm structure limits compression and keeps your body evenly supported throughout the night.
Softer surfaces can make movement feel restricted. A responsive, firm three-layer construction makes turning easier and helps your body stay stable as you move.
Sleeping hot can disrupt your rest and cause frequent wake-ups. The natural horsehair layer improves airflow and moisture control, helping release heat and maintain a cooler, drier sleep environment throughout the night.
Create a calm and balanced sleep environment inspired by natural materials.
A multi-layer firm latex construction enhanced with a natural horsehair layer — designed to deliver maximum support, improved airflow, and long-lasting structural stability.
Breathable natural fabric that regulates temperature, manages moisture, and creates a clean, comfortable sleep surface.
Placed directly beneath the cover, the horsehair layer improves airflow and moisture control at the surface level. It helps release heat and humidity more efficiently, creating a cooler, drier, and more breathable sleep environment.
A firm latex layer on top provides immediate support and helps keep your spine aligned from the first point of contact. Zoned support adapts to different parts of the body for better pressure distribution.
Two firm latex layers form a reinforced base structure that keeps your body elevated and stable. This core resists deep compression, distributes weight evenly, and maintains consistent support over time.
Stabilizes the mattress and supports long-term durability.
Natural latex provides responsive pressure relief and adapts to the body's natural curves.
Breathable natural fibres help regulate temperature and manage moisture.
Naturally breathable horsehair improves airflow and moisture control for a cooler, more comfortable sleep.
Natural materials allow air to circulate through the mattress and help reduce heat build-up during sleep.

Ensures the latex is made from certified organic raw materials and meets strict environmental and social standards.
Covers organic cotton and wool, ensuring responsible production, safe processing, and traceability.
Dunlop latex is a natural material made from the sap of rubber trees, processed using a traditional molding and vulcanization method.
During production, the latex is poured into a mold and gently settles, creating a slightly denser and more stable structure. This results in a more supportive and durable material compared to other latex types.
It has a naturally elastic feel, allowing it to respond to body movement while maintaining consistent support throughout the night.
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.

This mattress is currently configured as Soft.
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.
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.
Higher resistance with reduced compression.
This setup increases structural support and limits surface deformation.
Different firmness levels on each side of the mattress.
Each side operates independently within the same structure.
Sleep, move, and use your bed freely — with support that stays consistent across the entire surface.
No need to avoid the sides. The mattress feels just as supportive at the edge as it does in the center.
Stable support helps reduce rolling toward the middle. Both sleepers can comfortably use their full side of the mattress.
The slimmer design takes up less visual and physical space. Ideal for smaller rooms, minimalist setups, or lower bed frames.

Pelvic → controlled resistance
Knee → transition zone
Lower legs / feet → lower resistance

Coconut fibre: used in hybrid models
Horsehair: used in selected models
Breathable natural materials help maintain a comfortable sleep temperature throughout the night.
Air moves freely through the mattress instead of being trapped around your body, helping you maintain a more comfortable sleep temperature.
Natural fibres absorb and release moisture, reducing that warm, damp feeling and keeping your sleep surface more balanced.
The internal structure allows continuous airflow, so the mattress stays light, airy, and comfortable throughout the night.
Delivered in manageable boxes for easier transport and setup.
The Naturalist mattress is delivered in several manageable boxes instead of one large package, making transportation much easier.
Smaller boxes are easier to carry through narrow staircases, elevators and hallways.
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.
