What is the difference between a standard and tall gas cylinder on a drafting chair?

A standard gas cylinder on a drafting chair typically provides a seat height range of about 24"–33". A tall or extended cylinder pushes that range up to approximately 27"–37". If you're working at a very high counter (36"–40" surface height), the tall cylinder option is often the only way to achieve a comfortable ergonomic position. Always compare the work surface height to the chair's maximum seat height — you generally want your elbows at or just below table height when seated.
