A telescopic arm 10 for supporting a load, such as a monitor, defines a longitudinal axis x and comprises: a first arm portion 11; and a second arm portion 12, wherein the telescopic arm 10 is arranged to contract and/or extend along the longitudinal axis x by one of the arm portions moving linearly relative to the other arm portion, and wherein the first and second arm portions 11,12 are engaged one with the other such that linear motion of the first arm portion 11 relative to the second arm portion 12 causes rotation of the second arm portion 12 about the longitudinal axis relative to the first arm portion 11, and such that rotation of first arm portion 11 about the longitudinal axis relative to the second arm portion 12 causes linear motion of the second arm portion 12 relative to the first arm portion 11, and wherein the telescopic arm 10 further comprises a resilient bias arranged to resist rotation of the first arm portion 11 about the longitudinal axis relative to the second arm portion 12. |
