Find your ideal comfort level

Three distinct feels designed to match different sleep needs, body types, and preferences.

Soft comfort

More contouring, less pressure

Best for sleepers who need more comfort and adaptability:

  • Side and combination sleepers
  • Prefer a softer, more adaptive feel
  • Helps relieve pressure on shoulders and hips
  • Reduces numbness and pressure build-up
  • Allows easier movement and position changes

Medium firm comfort

Balanced support and comfort

Best for sleepers who want both support and pressure relief:

  • Combination sleepers
  • Back sleepers who prefer a slightly softer feel
  • Balanced comfort without excess sinking
  • Even weight distribution across the body
  • Supports natural spine alignment

Firm support

More structure, less sinking

Best for sleepers who need more stability and support:

  • Back and stomach sleepers
  • Heavier sleepers
  • Prefer a firmer, more supportive feel
  • Helps prevent hips from sinking too deeply
  • Reduces lower back strain and supports stable sleep

Naturalist firmness configurations

This mattress is currently configured as Soft.

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.

Learn more

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.

Dual Comfort

Current configuration

Different firmness levels on each side of the mattress.

Each side operates independently within the same structure.

Sleep closer to nature

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

Inside the Naturalist Full Latex Plus Dual Comfort Mattress

Two independent comfort systems in one mattress - each side adjustable for a more precise, personalized feel.

1

Organic cotton and wool cover

Breathable natural fabric that helps regulate temperature, manage moisture, and create a clean, comfortable sleep surface.

2

Dual adjustable latex comfort layers

Each side of the mattress is built with three interchangeable latex layers that can be arranged independently. This allows each sleeper to fine-tune their side - from firmer, more supportive setups to softer, more pressure-relieving configurations.

3

Independent latex base layers

Each side has its own supporting base structure, ensuring both sleepers experience consistent support without affecting each other’s comfort.

Natural materials that support healthier sleep

The Naturalist Hybrid Mattress is made using certified natural materials selected for breathability, durability and comfort.

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.

Breathable natural structure

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

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

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.
