The Difference Between Memory Foam and Regular Foam

Memory Foam, also known as slow-rebound foam, is relatively difficult and costly to manufacture. Today, memory foam is mainly used for body protection and can also be found in specialized equipment and high-value products. For example, in high-speed aerospace and aviation applications, it can absorb kinetic energy and vibration. In static environments such as sleeping and prolonged sitting, it deforms to distribute body weight and surface contact pressure more evenly, helping maintain a low-pressure environment for soft tissue circulation. In applications requiring posture support, it provides gentle support.

Characteristics of Memory Foam:

When you press your hand onto a flat memory foam surface, a handprint will appear and then slowly disappear. This is the distinctive slow-rebound characteristic of memory foam, and it is difficult for other materials to replicate such a slow recovery speed.

Memory foam feels soft to the touch. When you hold and squeeze it, you can feel it gradually compressing with very little immediate push-back force, making it comfortable to squeeze even for a long time. When lying on a memory foam mattress or cushion, you can feel the foam gradually sinking and conforming to your body, while sometimes hearing the subtle movement of air within the foam. When sitting against a memory foam lumbar cushion, the foam initially continues to deform and then gradually conforms to the body, reducing the feeling of resistance and helping improve comfort during prolonged sitting.

Conventional foam is available in many different densities, such as 16 kg/m³, 18 kg/m³, 20 kg/m³, 22 kg/m³, and more.

Through improvements in manufacturing processes, conventional foam can provide better resilience, load-bearing performance, and environmental performance.

Advantages of Conventional Foam:

1. Better resilience, approximately 5–10% higher than traditional foam;
2. Better support and excellent load-bearing capacity;
3. No tin-based catalysts are used during production, making the product cleaner and more environmentally friendly.

Applications of Conventional Foam:

Conventional foam is widely used in mattresses, sofas, automotive seats, cushions, and other products.

Differences Between Memory Foam and Conventional Foam:

Memory foam has a longer service life and can provide heat conduction, heat dissipation, and cooling properties. It has shape-memory and pressure-relieving properties, as well as sound absorption and noise-control capabilities. It is generally used in bedding products.

Conventional foam provides better resilience, load-bearing performance, and environmental performance. It is generally used in furniture and automotive seats.

Foam is available in many different types, including conventional foam, high-resilience foam, gel memory foam, slow-rebound memory foam, furniture foam, and more.
