What are the differences between rebound cotton and memory cotton?

　　I. Differences between Rebound Cotton and Memory Foam

　　Rebound cotton, also known as resilient cotton, is a filling material made by cutting a high-molecular material—polyurethane—into fibers and then cross-cutting or vertically cutting these fibers to create an elastic state. Rebound cotton has excellent elasticity and support, and is mostly used where support is emphasized, commonly found in bedding and sofa cushions.

　　Memory foam, also known as compression resilient cotton, is a material made from polyurethane foam. Memory foam can adjust its firmness according to body temperature and weight, gradually adapting to the human body shape. It can relieve pressure for different people, ensuring that people of different weights can have a comfortable experience.

　　II. Usage Scenarios of Rebound Cotton and Memory Foam

　　1. Bedding

　　In bedding, rebound cotton is a better choice to ensure human comfort and support. Because rebound cotton can provide better support, the neck, waist, and other parts of the body that need support while resting can be better supported, but overly hard rebound cotton may affect sleep quality.

　　Memory foam is suitable for larger body contact areas such as the shoulders and back, which are softer parts, and can more effectively relieve body pressure. It can be used to create fillings that conform to the curves of the human body, ensuring comfortable and quality sleep.

　　2. Sofa Cushions

　　In sofa cushions, rebound cotton is often a better choice because a relatively stable support environment is needed. Due to its good support and elastic rebound rate, it is not easily deformed during long-term use, maintaining good elastic support and better meeting the comfort we need in seating.

　　Of course, if you prefer a more massage chair-like feel, you can use sofa cushions containing more memory foam material. This will provide you with a different sitting experience, depending on your individual needs and preferences.

　　III. Summary

　　In summary, rebound cotton and memory foam are frequently used fillers in daily household life. Rebound cotton has better support and elastic rebound rate, making it suitable for bedding and sofa cushions; memory foam has better comfort and adaptability, suitable for neck pillows, car seat cushions, lumbar support pillows, etc. Therefore, when purchasing fillers, you need to choose according to your actual needs and personal preferences.
