It seems like there might be a typo in your query. It's possible you meant "dryer stand." If so, a dryer stand is a piece of equipment commonly used in hair salons and barber shops to hold and support a hair dryer during styling or drying procedures. 
The height of the stand is often adjustable to accommodate different clients and styling positions.
Some dryer stands may have additional features such as a swivel arm or wheels for ease of movement.
