Sponge Cover

Sponge cover is a type of bookbinding that incorporates a soft, padded inner layer made from a spongy material, typically designed to add extra durability and protection to the book. This cover not only provides a cushioned feel but also gives the book a thicker, more substantial texture. The padding helps to safeguard the contents of the book from wear and tear, while also offering an attractive and tactile aesthetic. Sponge covers are often used for high-quality, premium books, contributing to both their longevity and overall visual appeal.
