The name excelsior originated in America and excelsior has been manufactured in the United States for over a century. Excelsior consists of thin, narrow, curled strands of Great Lakes Aspen which have barbed edges that provide an interlocking feature. In the United States, excelsior has no other general name; however, in many other countries, excelsior is commonly known and referred to as wood wool.

Another property of excelsior of great importance is its resiliency, which is the ability to readily expand after compression. The combination of resiliency and the interlocking feature of the fibers makes excelsior highly suitable for many diverse applications.
