Before inventing her improved ironing board, Sarah Boone likely observed the difficulties faced by seamstresses and others in ironing garments, particularly those with sleeves and close-fitting forms. This observation likely sparked her interest in finding a solution.

Sarah Boone invented a new and improved ironing board, designed to make ironing sleeves and the bodies of women's garments easier. Her design was narrower and curved, offering a better fit for these types of items.

Sarah Boone filed a patent application for her invention on April 26, 1892. This marked a crucial step in securing legal protection for her design and the potential for commercializing her invention.

The United States Patent Office granted Sarah Boone U.S. Patent No. 473,653 for her improved ironing board on April 25, 1893. This achievement made her one of the few African American women inventors to receive a patent during that era. Her invention was officially recognized and protected by law.

Following the patent grant, Sarah Boone likely explored manufacturing and marketing options for her ironing board. The extent of her success in commercializing her invention is not well documented, but she undoubtedly worked towards promoting and selling her innovative design.
