Sponginess describes a texture that is soft, porous, and absorbent, much like a sea sponge 🧽. It's that yielding, bouncy quality you feel when you poke something and it slowly returns to its original shape. Think of the way a freshly baked cake feels when you press lightly on its surface. Sponginess isn't about being sticky or wet, but more about the material's ability to soak up liquids and cushion impacts. Unlike hardness or rigidity, sponginess offers a degree of give and flexibility. A memory foam mattress has sponginess, while a rock does not.
