A presentation stand is a type of support used to display materials such as posters, artwork, or other visual aids. The two most common types of presentation stands are easels and daises. An EASEL is a three-legged stand that can be adjusted to different heights and angles. It is typically used to hold a poster or painting in an upright position. A DAIS is a four-legged platform that is usually higher than the surrounding area. It is often used to elevate a speaker or presenter so that they can be seen and heard by the audience.
