Double action mechanism

This is a double action mechanism, also known as a synchro mechanism. The mechanism consists of two pivoting points where the seat and back tilt at a ratio of 1:2. In an ergonomically optimal action, the pivoting points will be as close as possible to the user’s knee joint and hip joint, ensuring that the seat and back move in perfect symmetry with the body. The technology is suitable for high funtion ergonomical office chairs and excecutive chairs.
