A work or office chair having a seat shell which is pivotably arranged on a height-adjustable seat carrier, characterized by the seat shell being spring loaded to oppose tilting of the seat shell from a raised position towards a tilted, lower position. The chair includes a fixing arrangement for fixing the chair in specific tilted positions. One improvement is a spring arrangement for supporting the chair and a toggle arrangement coacting with the spring arrangement for opposing tilting of the chair with the springs of the toggle arrangement and the supporting spring coacting to require a substantial force to cause initial tilting then followed by a gradual force to cause tilting.
