Firmness Regulation
Based on Your Body Proportions
Dunlop Firmness Regulation
These are Dunlop regulations
Based on engineering research.
Engineering view
An engineering view of your sleep. Enter your height and weight below and our regulation rules calculate your firmness, density and model.
Seven zones run under the body: head, shoulder, back, pelvis, knees, legs and ankles. Each one carries a different share of your weight, so the heavy pelvis is held firmly while the lighter head and shoulders settle in. The bars show how support is distributed between the zones.
The shoulder is the widest part of a side sleeper and it takes a large share of the load. The latex yields here, so the shoulder settles into the surface instead of being pushed back, and the spine can stay level.
Under the waist the latex rises to meet the natural curve of the lower back. It supports the hollow without pushing into it, so the spine keeps its neutral line.
The pelvis carries the most weight. This zone is reinforced, so the hips do not sink below the shoulders and the spine is not bent out of line.
When the spine rests in a neutral line, the muscles around it can let go and the spine lengthens gently into its natural shape. The drawing shows the principle. It is not a medical measurement.
Latex is elastic. It gives under muscle and soft tissue and comes back, following your shape without holding it, so muscles are not working to push against the surface.
Latex spreads your weight over a wider area, so no single point carries too much. Lower, more even pressure helps you stay comfortable and change position freely.
This is the real thing: a person on natural Dunlop latex. Open cells and high elasticity let it press in under load and return straight away, which is why it can support and adapt at the same time.

1Your regulation what carries your body, and what lets it rest
These are the base levels by body weight. Your height and your answers fine-tune the result.

3Why it is right the engineering behind your answer
A regulation that protects your choice. Every value rests on engineering and sits within the range of human proportions.
Throughout, we give a regulation that protects your choice, so there is nothing to worry about when you buy online. Every value rests on engineering and sits within the range of human proportions.
A latex mattress can only be judged lying down. When you sit, your weight concentrates in one small area and the latex cannot absorb it properly. Lying down spreads your weight over the whole surface, so the body rests on top of the latex mattress, the way it does all night.
We look at one thing: the balance between anatomical adaptation and orthopaedic support. One cannot work without the other. A latex mattress that is too soft lets the body sink and gives no support. A latex mattress that is only hard cannot adapt, so the muscles cannot let go and the nervous system cannot relax. Circulation and sleep then become less complete.
High adaptation needs a platform under it. Latex adapts well only when the core beneath carries the body and gives stability, and the adaptive surface builds its comfort on top of that. Adaptation is not a replacement for support. It rests on support: a surface that yields without a base does not carry you, it only gives way.
Everyone may adjust to their own feel. That is why the Dual Plush concept exists. It starts from the regulation for your body and adds the extra comfort you need on top of it. Regulation plus regulated freedom is what makes the choice right.
Each firmness is a different density of Dunlop latex. Density carries your weight. Elasticity lets the surface follow your body. Your weight selects the density, the way a size is selected, so the same body always gets the same answer.
A regulated mattress gives the structure. A separate latex topper, one level softer, regulates the surface. Only three mixes exist, always neighbouring levels, so the support stays correct. Layers are never stacked at random.
Lying on your side, your shoulder and hip must sink in while your waist is carried. Only then does the spine stay straight.
The body rests on the shoulder, so the support is concentrated, not distributed. The middle arches up and the spine arches with it.
The pelvis sinks further than the legs and the body hangs in a gentle reverse arch. The spine bends down with it and the anatomical balance is lost.
Shoulder and hip sink exactly as far as they need, the waist is carried and the seven vertebrae sit in one straight line. This is the balance Dunlop regulation looks for, the one in the model above.
A latex mattress is made for lying down. Sitting on it, or bouncing on it, tells you nothing about how it carries your sleep.
Seated, most of your weight rests on the small area under your pelvis. The same weight on a much smaller area means much higher pressure, so the surface gives way and you sink in. This is normal, and it says nothing about how the mattress carries you in sleep.
Lying down, the same weight is spread over the whole length of your body, from head to ankles. The open cells of the latex answer each zone in proportion, so you rest on top of the surface, not in it. This is where a latex mattress does its job, and where its resilience belongs.
Test a latex mattress lying down, in your own sleeping position.
We do not read kilograms alone. We read how your weight is distributed.
Spread over a wider area, 70 kg stays in Medium.
Gathered on one area, the same 70 kg needs Firm, or Dual Plush.
Same kilograms, different distribution. That is why we look beyond the number on the scale.
This is the system we follow.
We do not sell firmness as a word.
We regulate adaptation and support.
Do not start from the words Soft, Medium or Firm as a feeling. Start from the regulation.
Once the right mattress has been chosen, the next steps become much easier. And when more freedom and finer refinement are needed, we also have solutions such as Dual Plush, where a latex topper with a different but close firmness upgrades the comfort without damaging the correct support or the engineering logic.
DUAL PLUSH – ENGINEERED REGULATION SYSTEM
Dual Plush works on a simple logic: weight first, preference second.
The system starts with 4 Dunlop firmness regulations. These are engineering load categories based on body weight. They define the correct mattress firmness. From there, preference determines which engineered direction is applied, without leaving the regulation.
Firmness regulations by body weight
• Soft – up to 47 kg
• Medium – 47–88 kg
• Firm – 88–120 kg
• Extra Firm – over 120 kg
Engineering principle
Mattress = structural foundation
Topper = comfort surface regulator

ENGINEERED EXAMPLES
This is how the system works in real life. Same weight. Different preference. Still inside regulation.
EXAMPLE 1 – 75 KG
Regulation → Medium (47–88 kg)
Inside this regulation, two possible directions exist.
1.1 – 75 KG, WANTS MORE COMFORT
Mattress → Medium
Topper → Soft
• Softer comfort surface
• Increased anatomical adaptation
• Correct structural stability
1.2 – 75 KG, WANTS MORE SUPPORT
Mattress → Firm
Topper → Medium
• Stronger structural resistance
• Controlled comfort surface
• More orthopaedic stability
Same weight.
Different preference.
Still inside regulation.
EXAMPLE 2 – 93 KG
Regulation → Firm (88–120 kg)
Again, two possible directions exist.
2.1 – 93 KG, WANTS MORE ADAPTATION
Mattress → Firm
Topper → Medium
• Correct load support
• Softer comfort surface compared to full Firm
• Balanced anatomical feel
2.2 – 93 KG, WANTS MAXIMUM SUPPORT
Mattress → Extra Firm
Topper → Firm
• Maximum structural resistance
• Firm comfort surface
• Minimal compression
• Strong orthopaedic stability
⸻
THE THREE ENGINEERED MIXES
From the examples above, the system becomes clear.
There are only three calibrated configurations. This is why the selection is secure.
LIGHT MIX
(under 70 kg → Mattress Medium + Topper Soft)
Creates a softer comfort surface while maintaining correct structure.
SAFE MIX
(70–95 kg → Mattress Firm + Topper Medium)
Creates balanced structural control with a regulated comfort surface.
POWER MIX
(over 95 kg → Mattress Extra Firm + Topper Firm)
Creates maximum structural resistance and orthopaedic stability.
⸻
IMPORTANT
We do not create unlimited combinations.
We do not mix Soft with Extra Firm.
We do not stack contradictory thin layers.
Every configuration follows:
Weight regulation first
Engineered Mix second
Only three controlled mixes exist.

How to Choose the Right Mattress Firmness?
Many people with back pain or recovering from surgery believe they need a hard mattress to get proper support. But this isn’t entirely true. The key is not whether a mattress is hard or soft, but whether it’s right for your body and needs.
Why a Hard Mattress Isn’t Always the Best Choice?
A mattress that’s too firm can:
✔ Put too much pressure on sensitive areas.
✔ Misalign your spine, leading to further discomfort.
✔ Increase muscle tension, making pain worse.
On the other hand, a mattress that’s too soft won’t provide enough support, which can also cause discomfort and poor sleep quality.
Our Approach: Dual Comfort for Maximum Support & Care
Instead of choosing between hard or soft, Divine DunlopDreams offers a tailor-made solution – our Dual Comfort mattresses, designed to provide:
✔ A supportive base layer – matched to your body weight and proportions.
✔ A softer top layer – to reduce pressure on sensitive areas and provide a gentle feel.
Our BOTANIC DUAL and BIO COMFORT DUAL models combine these two layers to deliver the perfect balance of firmness and adaptability, ensuring maximum spinal alignment and comfort.
Example:
If your body needs a Firm mattress, we recommend:
Base layer: FIRM – for correct spinal support. Top layer: MEDIUM – to ensure better comfort for sensitive areas.
With BOTANIC DUAL and BIO COMFORT DUAL, you get both support and relief, allowing your body to rest naturally while reducing pressure on the spine.
Why is Latex the Best Choice?
Our 100% natural latex mattresses offer:
✔ Twice the density of standard materials, ensuring built-in support.
✔ 7-zone support system for perfect spinal alignment.
✔ Adaptability without sinking – latex distributes weight evenly, reducing pressure on key areas.
For Those Who Prefer a Firm Orthopaedic Mattress
We understand that some customers specifically look for a firm orthopaedic mattress, which is why we offer COCONUT Coir – our firmest model with orthopaedic support. This mattress is designed for those who need extra firmness and structured support.
However, choosing COCONUT Coir should be based on your personal orthopaedic needs, as ultra-firm mattresses are not suitable for everyone.
How Do We Ensure You Make the Right Choice?
All our firmness levels (Soft, Medium, Firm, Extra Firm) are based on real body proportions, not marketing labels. When you choose the right firmness for your body, your choice is guaranteed to be correct.
