When choosing a latex mattress, buyers increasingly pay attention not only to firmness but also to latex density. This parameter directly affects durability, resistance to sagging, and overall sleep quality.
What Is Latex Density
Latex density refers to the amount of material per cubic meter (kg/m³). It shows how much natural latex is inside the mattress and is not directly related to how soft or firm it feels.
Density determines durability and lifespan.
Firmness determines comfort sensation.
A mattress can feel soft while still having high density and long service life.
Why 85–90 kg/m³ Is Considered Optimal
Latex with a density of 85–90 kg/m³ adapts to body contours, reduces pressure on shoulders and hips, and maintains proper spinal support without sagging.
It retains its shape longer, withstands daily use, and is suitable for back, side, and stomach sleepers.
Natural Dunlop latex maintains an open-cell structure for good air circulation.
Density Comparison
70–75 kg/m³ — toppers
75–80 kg/m³ — standard
85–90 kg/m³ — everyday sleep
How Density Is Stated
Latex core density: 85–90 kg/m³
Calculated excluding the cover.
Conclusion
85–90 kg/m³ is the optimal choice for everyday sleep.
