Gazlift, also known as a gas spring or gas lift, is a mechanical device that uses compressed gas to provide a lifting or lowering force. It typically consists of a cylinder containing gas, a piston, and a rod, allowing it to extend or retract based on the applied pressure. Gazlifts are commonly used in applications such as office chairs, car hoods, and various types of furniture to facilitate smooth and controlled movement. They offer a convenient and efficient way to support heavy loads while minimizing manual effort.
