Understanding Mattress Density
What is Density?
Density measures how much material is packed into a given space, expressed as kg/m³ or lb/ft³. Higher density typically means better quality and durability.
Why It Matters
Density directly affects durability, support, and lifespan. Low-density foams compress quickly, while high-density materials maintain their shape longer.
Choosing Right
Consider your body weight, sleep position, and durability needs. Our calculator provides personalized recommendations based on these factors.
Density Classification Guide
Memory Foam Density Standards
Low Density
24-32 kg/m³
Budget option, 3-5 years lifespan
Medium Density
32-48 kg/m³
Good quality, 5-7 years lifespan
High Density
48-64 kg/m³
Premium quality, 7-10 years lifespan
Ultra High
64+ kg/m³
Luxury grade, 10+ years lifespan

Density Selection Guide
By Body Weight
Under 60kg (130 lbs)
Medium density (24-40 kg/m³) provides adequate support without being too firm
60-90kg (130-200 lbs)
Medium to high density (32-48 kg/m³) offers balanced comfort and support
Over 90kg (200 lbs)
High density (48+ kg/m³) ensures proper support and prevents premature sagging
By Sleep Position
Side Sleepers
Medium density (32-45 kg/m³) for pressure relief while maintaining support
Back Sleepers
Medium to high density (35-50 kg/m³) for spinal alignment and support
Stomach Sleepers
High density (45+ kg/m³) to prevent sinking and maintain proper alignment
Frequently Asked Questions
How does density affect mattress lifespan?
Higher density materials resist compression and maintain their shape longer. Low-density foams (under 32 kg/m³) typically last 3-5 years, while high-density foams (48+ kg/m³) can last 8-12 years with proper care.
Is higher density always better?
Not necessarily. While higher density generally means better durability, it can also mean a firmer feel and higher cost. The optimal density depends on your body weight, sleep position, and personal preferences for firmness and support.
What's the difference between density and firmness?
Density measures how much material is in a given space and affects durability. Firmness is how the mattress feels when you lie on it. A high-density foam can be made to feel soft through design and layering techniques.
How accurate is the weight calculation?
Our calculator uses industry-standard density values and is typically accurate within 10-15% of actual weight. Variations can occur due to manufacturing tolerances, moisture content, and specific material formulations.
