What dimension is recommend for a typical seat height?

For a typical seat height, 18 inches is widely recommended as it aligns with ergonomic standards and accommodates a majority of the population comfortably. This height allows individuals to sit with their feet flat on the ground, thighs parallel to the floor, and arms at a comfortable level to interact with a table or desk. The 18-inch measurement is also commonly used in various types of seating, from dining chairs to office chairs, making it a standard in design practices.

In contrast, dimensions like 15 inches or 12 inches might be too low for most adults, resulting in poor posture and discomfort, especially over extended periods. On the other hand, 20 inches could be too high for many users, potentially leading to difficulty in sitting down and standing up, and not allowing for the proper ergonomic positioning that is vital for comfort and health in seating arrangements. Thus, 18 inches is ideally suited as a standard seat height that supports diverse users while promoting good posture and comfort.
