Back sleepers

Firm support helps maintain the natural curve of your spine and prevents your lower back from sinking.

Stomach sleepers

Sleeping on your stomach can strain your lower back if the mattress is too soft. Firm support keeps your hips from sinking too deeply, helping maintain a healthier spinal position.

Heavier sleepers

Stronger structural support keeps your body properly aligned without excessive compression.

Sleepers who prefer a firm feel

Provides a stable, supportive surface without the “sinking” sensation of softer mattresses.

Designed for back sleepers and heavier sleepers who need stronger, stable support

The Hybrid Firm construction focuses on spinal alignment, controlled support, and stability -helping your body stay properly supported throughout the night.

Lower back strain & poor alignment

Back sleepers often experience lower back tension when the hips sink too deeply into the mattress. A firmer structure keeps your spine aligned and prevents your lower back from collapsing.

Sinking too deeply

Memory foam can make you feel “stuck” in one position, limiting movement during the night. This is especially problematic for stomach sleepers, as the hips can sink too deeply and strain the lower back. A firmer structure keeps your body lifted and properly aligned.

Overheating

Trapped heat can disrupt sleep and cause discomfort. Open, breathable natural materials allow air to circulate freely and help regulate temperature throughout the night.

Lack of support for heavier sleepers

Heavier sleepers may not get enough support from softer materials, leading to uneven pressure and misalignment. Stronger layers provide consistent support without excessive compression.

Sleep closer to nature

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

Organic cotton and wool cover

Breathable natural fabric that helps regulate temperature and manage moisture.

7-zone natural latex comfort layer

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

Coconut fibre support layer

Natural coconut fibre improves structural stability and airflow.

Zoned pocket spring system

Individually wrapped springs support the spine and adapt to body weight.

Coconut fibre base layer

Stabilizes the mattress and supports long-term durability.

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.

Breathable natural structure

Natural materials allow air to circulate through the mattress and help reduce heat build-up during sleep.

Certifications

GOLS certified latex

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

GOTS certified textiles

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

Dunlop latex

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.

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.

7-zone latex

Zone structure scheme

Pocket springs

Zoned support
• 7-zone support structure
• Softer zones at shoulders and hips — pressure relief
• Firmer lumbar zone — prevents excessive sinking
• Balanced zones — maintain overall stability

Technical specifications
• Barrel-shaped springs
• ~462 springs (90×200 cm)
• ~396 springs (80×200 cm)
• 14 × 33 / 12 × 33 layout (high-density)
• Dual-gauge steel (1.6 mm / 1.8 mm)

Construction & airflow
• Side-connected structure for stability
• Open design improves airflow and moisture control

Natural materials

Cover materials
• Cotton and wool blend
• GOTS-certified (supplier level)
• Naturally breathable and moisture-regulating

Latex core
• Natural Dunlop latex
• GOLS-certified (supplier level)
• Durable, elastic, and supportive

Additional natural layers
• Coconut fibre — used in hybrid models for added structure
• Horsehair — used in selected models for enhanced airflow and moisture control

Soft

Lower resistance, allowing deeper compression under load.

This configuration enables greater surface deformation before resistance increases.

Recommended for:

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

Current configuration

Firm

Higher resistance with reduced compression.

This configuration increases structural response under load and limits surface deformation.

Recommended for:

Back sleepers
Stomach sleepers
Higher body weight
Sleepers requiring reduced sink

Dual Comfort

Different firmness levels on each side of the mattress.

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 firmness by changing the internal base setup - a simple way to adapt comfort to your preference.

The Hybrid mattress is built as a modular system with separate internal components.

Depending on how the internal base layer is positioned, the mattress can create two different comfort feels.

One setup offers a firmer, more supportive feel that helps keep your spine aligned. The other provides a slightly softer surface for increased pressure relief and comfort.

This gives you more flexibility over time — without needing a completely different mattress.

Strong edge support, no wasted space

Sit, sleep, and move freely - with support that stays consistent from edge to edge.

A firm place to sit and stand up

No sinking feeling when sitting on the edge - just stable support when you need it most.

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

Less rolling toward the middle means fewer interruptions and more personal space for both sleeper.

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.
