Pressure and sleep
The science of why you keep turning over
Five steps from body weight to a broken night.
Your weight lands on a few points
Shoulders, hips and pelvis take a disproportionate share of your body weight the moment you lie down.
The load doesn't stop at your skin
It travels down through muscle and fascia into the corridors where nerves and blood vessels run.
Those corridors get squeezed
The structures serving your whole arm or leg sit directly beneath the point your weight lands on.
Your body raises the alarm
Numbness, pins and needles, a dull ache, and the urge to move.
You turn over
And every one of those position changes can break your REM or NREM cycles.
Five factors
Five ways your mattress affects overnight recovery
Two act on where your body meets the bed. Three act on the night as a whole.
The shoulder corridor
The problem
Your smallest contact point takes your heaviest load — directly over the nerves serving your whole arm.
What Nidraka does
Latex gives way around the shoulder instead of pushing back at it.
The hip and pelvis
The problem
Hip and tailbone have almost no padding, and sit over the paths serving your glutes and legs.
What Nidraka does
Load spreads wider, so the bony points carry less of it.
Deep sleep and repair
The problem
Every pressure wake-up, even one you never remember, costs you deep sleep — when most repair happens.
What Nidraka does
Fewer wake-ups means more of the night spent recovering.
Overnight temperature
The problem
Your core temperature has to fall for deep sleep. Trapped heat works against it.
What Nidraka does
Open-cell latex lets heat leave instead of building up under you.
Your partner's movement
The problem
On a spring mattress, someone turning over a metre away still reaches you.
What Nidraka does
Latex compresses locally, so movement stays close to where it happens.

The evidence
Backed by published research
How latex compares with the two materials most mattresses are built from.
Nidraka vs polyurethane foam
Journal of Chiropractic Medicine, 2016Effects of Mattress Material on Body Pressure Profiles in Different Sleeping Postures
See results and conclusion
Peak interface pressure on latex was 26.1% lower at the torso and 28.4% lower at the buttocks while back sleeping. Across the measured regions, 90.9–96.1% of contact area on latex fell in the lowest pressure band, against 82.1–91.8% on polyurethane foam.
Twenty healthy adults, latex vs polyurethane foam across three sleeping postures. This study did not test Nidraka.
Nidraka vs memory foam
Surface EMG study, 35 adultsErgonomic assessment of four different mattresses
See results and conclusion
Participants were measured with surface EMG while turning over on four mattresses. Memory foam performed well while subjects lay still, but required greater muscle activation during turning. Latex showed the lowest activation of the surfaces tested and was rated most comfortable overall.
Memory foam is good at relieving pressure. The difference is not pressure. It is what happens when you move.
The numbers
What the studies measured
Published figures from the research above, not from testing on Nidraka.
Peak pressure at the back torso, back posture. Low et al, J Chiropr Med 2016. 20 adults. Did not test Nidraka.
Share of body surface area at 0–0.6 psi across five regions. Same study. Higher is better.
Randomised crossover trial. Lower muscle activity is better for sleep quality.

Materials
Every layer, explained
Most brands will not tell you the density of what you are sleeping on. Every layer below is named, specified and measurable. We think the rest of the industry should do the same.
1 Soft-Knit Breathable Cover
Soft-knit cover that stretches and breathes, so heat doesn't build up against your skin.
Composition
High-performance polyester blend
Origin
Made in India
2 Fibreglass-Free Fire Barrier
Meets flammability standards without fibreglass, so nothing irritating can ever escape the cover.
Composition
Knitted rayon blend
Certification
Fibreglass-free
3 Pressure-Relief Layer
Contours and distributes from your shoulders and hips so you can settle without pressure points building overnight.
Composition
Open cell 100% natural latex
Density
75 Density*
Origin
Imported from Thailand
Role
Pressure relief and contouring
4 Stable Base Layer
A dense base that anchors the layers above, keeps the mattress flat on any bed frame and holds its shape for years.
Composition
High-resilience (HR) foam
Density
35 Density*
Firmness
Medium-firm
Role
Stability and long life
5 Heat Dissipating Side Covers
Fibrous Side covers that radiate heat out of the mattress and promote circulation to keep it cool all night.
Composition
Conductive Fibre Fabric
Role
Temperature regulation
* Plus or minus 5 density is possible as a natural manufacturing variation.
Firmness
Holds you up without pushing back.
Too firm and pressure concentrates at your shoulder and hip. Too soft and you lose the stable support that keeps your spine aligned and makes turning easy. At a 7/10 firmness, you'll feel stable and grounded, with just enough give to relieve pressure at your shoulders and hips.
Responsive by design
Absorptive Bounce
Responsive latex that absorbs impact and springs back. That responsiveness is what stops you sinking into a dent by year three, and what lets you turn over without waking your partner.
Why we cost more
Nidraka vs Other Latex Mattresses
There are 2 types of latex mattresses in the market. Budget latex that usually costs from 7k-20k and Premium Latex that is from 15k-40k. This is how we compare against them

Invented Jargon Names to Make Cheap Foam Seem Expensive
If we seem more expensive that other latex mattresses its because - We use 100% natural latex. We use high density materials so they last long. And we don't use jargon like AirTech or CoolMaxPro to make cheap foam seem expensive.

Straight answers
But what about...
Delivery, returns and the questions worth asking before you buy a mattress online.
What if I don't get on with it?
Sleep on it for 100 nights. If it isn't right, message us and we arrange collection from your door and refund you in full.
No restocking fee, no return shipping to pay, and nothing for you to re-roll or repack. You don't need the original box, and we won't ask you to justify it.
Why 100 nights, when the rest of Cosylabs is 10 days?
Because a mattress isn't a sofa cover. Your body takes weeks to adjust to a new sleep surface, and the first few nights on any mattress tell you very little.
Cosylabs products carry our standard 10-day return window. Nidraka gets 100 nights because that is honestly how long it takes to know.
Where do you deliver, and how long does it take?
We deliver to every pincode in India, and shipping is free everywhere. Your mattress is dispatched within 72 hours of ordering.
After that, expect 2–3 days across North India and 3–5 days for the rest of the country.
Is one inch of latex really enough?
Your body only interfaces with the top surface. The latex layer is what manages pressure at that interface; the seven-inch high-resilience core underneath is what provides the support structure.
Making the latex layer thicker changes the price far more than it changes what you feel.
Doesn't latex sleep hot?
Natural latex is open-cell and pinhole-cored, so air moves through it. It is not the coolest surface money can buy — actively cooled and high-airflow surfaces perform better in testing — but it traps considerably less heat than dense viscoelastic foam.
I'm heavier than average. Will it hold up?
Support comes from the seven-inch high-resilience core, which is specified by density and resilience rather than thickness alone.
If you are near the top of the weight range, message us before you order and we will tell you honestly whether this is the right mattress for you.
I've read that latex causes allergies.
Latex allergy is associated with residual proteins in dipped latex products such as gloves and balloons. The vulcanised foam latex used in mattresses is produced differently and sits under a cover you never touch directly.
If you have a diagnosed latex allergy, speak to your doctor before buying.
What does the warranty cover, and how do I reach you?
Nidraka carries a 10-year warranty against manufacturing defects.
