Final answer:
The typical seat height of an upholstered easy or club chair is between 17 to 18 inches, which is ergonomically comfortable for most adults.
Step-by-step explanation:
The typical seat height of an upholstered easy or club chair can vary depending on the specific chair design and manufacturer. However, a common range for seat heights is between 18 to 20 inches (45.7 to 50.8 cm).
This range is comfortable for most individuals and allows their feet to rest flat on the floor. It's important to note that some chairs may have adjustable seat heights, so be sure to check the specifications or measurements provided by the manufacturer. For example, a popular club chair might have a seat height of 19.5 inches (49.5 cm), making it suitable for a standard dining table or desk height.
