The natural elasticity of 100% cotton sofa fabric is relatively low compared to some other textile materials, such as spandex or elastane. Cotton fibers are not inherently highly elastic like these synthetic fibers. Instead, cotton is known for its natural flexibility and slight stretchability. Here's a closer look at the natural elasticity of 100% cotton sofa fabric:

Slight Stretchability: Cotton fibers have a limited ability to stretch and recover their original shape. This slight stretchability makes cotton fabric comfortable to sit on and wear, as it can accommodate some movement without losing its structural integrity.

Natural Flexibility: Cotton fibers are naturally flexible, allowing them to bend and move with ease. This flexibility contributes to the overall comfort of cotton upholstery and makes it suitable for a wide range of seating applications.

Recovery: While cotton can stretch slightly, it doesn't have strong elastic properties. After stretching, cotton may not bounce back to its original shape as readily as highly elastic materials do. This is why cotton is often blended with other fibers like spandex or elastane to enhance its stretch and recovery.

Weave and Construction: The natural elasticity of cotton fabric can also depend on its weave and construction. Different weaving techniques and fabric structures can affect the fabric's overall stretchiness. For example, jersey knit cotton fabrics tend to be more elastic than tightly woven cotton fabrics.

Comfortable Drape: Cotton's natural flexibility and drape contribute to its comfortable and soft feel. This drape is important for creating a relaxed and inviting appearance in sofas and upholstery.

While cotton's natural elasticity is not as pronounced as that of synthetic stretch fabrics, it is valued for its comfort, breathability, and softness. It provides a pleasant sitting experience and is suitable for furniture where a moderate level of give and flexibility is desired.
