Differences 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, memory foam can help absorb kinetic energy and vibration. In static environments such as sleeping or prolonged sitting, its ability to deform helps distribute body pressure more evenly and maintain a lower-pressure environment for soft tissues and blood circulation. In applications requiring posture support, it can provide gentle and comfortable support.

Characteristics of Memory Foam

When you press your hand onto a flat surface of memory foam, a handprint will appear and then slowly disappear. This slow recovery is one of the most distinctive characteristics of memory foam and is difficult for many other materials to imitate.

Memory foam feels soft to the touch. When held in the hand, it feels as though the material continues to sink inward, with very little push-back force, so squeezing it for a long time does not feel particularly tiring.

When lying on a memory foam mattress or cushion, the body gradually sinks into the material. You may also hear a slight sound as air moves through the foam cells.

When sitting against a memory foam lumbar cushion, the foam initially continues to deform and gradually conforms to the body. As the pressure becomes more evenly distributed, the feeling of resistance is reduced, providing more comfortable support during prolonged sitting.

Regular Foam

Regular foam is available in many different densities, such as:

• 16 kg/m³

• 18 kg/m³

• 20 kg/m³

• 22 kg/m³

• And other density grades

With improvements in production technology, regular foam can offer better resilience, load-bearing performance, and environmental performance.

Advantages of Regular Foam

1. Better Resilience
   Its rebound performance can be approximately 5–10% higher than that of some traditional foam products.

2. Better Support
   It provides good load-bearing and supporting performance.

3. Cleaner and More Environmentally Friendly Production
   Certain production processes can be designed without tin catalysts, helping to produce cleaner and more environmentally friendly foam products.

Regular foam is widely used in mattresses, sofas, automotive seats, cushions, and other applications.

Differences Between Memory Foam and Regular Foam

Memory Foam

Memory foam generally offers a long service life and has slow-rebound and pressure-relieving characteristics. It conforms to the shape of the body and helps distribute pressure more evenly.

It can also provide certain sound absorption and noise reduction properties.

Memory foam is commonly used in:

• Mattresses

• Pillows

• Bedding products

• Cushions

• Protective products

Regular Foam

Regular foam generally offers good resilience, load-bearing capacity, and a wide range of hardness and density options.

It is commonly used in:

• Furniture

• Sofas

• Mattresses

• Automotive seats

• Cushions

• Footwear materials

Common Types of Foam

Foam can be divided into many different types, including:

• Regular Foam

• High-Resilience Foam

• Gel Memory Foam

• Slow-Rebound Memory Foam

• Furniture Foam

• And other specialized foam materials

Different types of foam have different characteristics and should be selected according to the specific requirements of the final application.
