These allow the speaker to be raised slightly higher than the audience when using a podium that is on the same level as the audience.
Keeping safety in mind, and staying within the regulations for individual step heights, these can be used separately or in conjunction.
Thanks to Dennis Cracker for his suggestion to include cutouts for easy lifting when they need to be moved.
This was a simple project that provides a tool that will be used for years.
