Technical Explanation

Foam Density vs. Firmness

Foam density and firmness are two different technical specifications.

Density

Foam density mainly affects:

• Material durability
• Fatigue resistance
• Long-term performance
• Resistance to permanent deformation

Density does not directly determine whether a cushion feels soft or firm.

Firmness

Foam firmness mainly affects:

• Initial seating feel
• Compression resistance
• Perceived support level

The same density foam can be produced in soft, medium, or firm versions through different formulations and manufacturing processes.

Resilience

Resilience describes how quickly and effectively foam recovers after compression. It influences:

• Bounce response
• Recovery speed
• Long-term comfort consistency

Why Layered Construction Matters

A premium cushion is not created simply by using higher-density foam. The key is engineered layering:

• Soft pressure relief at the top
• Resilient support in the middle
• Stable reinforcement at the bottom

This layered approach creates a more balanced combination of comfort, support, and durability.

Seat Cushion Comfort System

Introduction

A premium sofa cushion is not defined by a single material, but by the balance between comfort layers, support structure, resilience, durability, and long-term performance.

Different cushion constructions create different seating experiences. Factors such as foam layering, filling materials, spring systems, cushion thickness, cover tension, and suspension structure all contribute to the final seating feel.

To help customers select the most suitable comfort preference, each cushion option is presented according to four key criteria:

• Comfort Level
• Cushion Construction
• Seating Characteristics
• Maintenance Requirement

Technical Explanation

Density, Firmness and Resilience

These three specifications describe different aspects of foam performance.

Foam Density

Density refers to the weight of foam material per cubic meter. Density mainly influences:

• Durability
• Fatigue resistance
• Long-term performance
• Resistance to permanent deformation

Higher density does not automatically mean a firmer or more comfortable cushion.

Foam Firmness

Firmness determines how the cushion initially feels when compressed. It affects:
