An arm for supporting a monitor , comprising: a telescoping arm assembly having at least first and second telescoping members telescopingly movable relative to each other, the assembly having a distal end configured to support a monitor (M) and a hollow interior through which at least one cord (C1, C2) from said supported monitor can be routed; a support member connected proximally of the distal end to suspend the telescoping arm assembly , the support member being configured to extend transverse to the telescoping arm assembly and to be able to be fixed to a support surface (S); a load balancing device (19; 120), in particular an air cylinder or a spring , positioned at least partially within at least one of the telescoping arm assembly or the support member , the load balancing device being configurable to exert a force to counteract a load exerted by the telescoping arm assembly and any attached monitor (M); and a cord storage device positioned at least partially within at least one of the telescoping arm assembly or the support member , wherein the cord storage device is suitable to wind and unwind the at least one cord (C1, C2) from said supported monitor as the first and second telescoping members are moved toward and away from each other, wherein the cord storage device comprises a fixed pulley and a movable pulley about which the at least one cord (C1, C2) can be stored, and wherein the movable pulley translates relative to the fixed pulley as the first and second telescoping members are moved towards and away from each other, characterized in that the fixed pulley and the movable pulley are each configured to store a first cord (C1), a second cord (C2), and a load supporting cable (C3), with said first and second cords (C1, C2) being part of the at least one cord. a telescoping arm assembly having at least first and second telescoping members telescopingly movable relative to each other, the assembly having a distal end configured to support a monitor (M) and a hollow interior through which at least one cord (C1, C2) from said supported monitor can be routed; a support member connected proximally of the distal end to suspend the telescoping arm assembly , the support member being configured to extend transverse to the telescoping arm assembly and to be able to be fixed to a support surface (S); a load balancing device (19; 120), in particular an air cylinder or a spring , positioned at least partially within at least one of the telescoping arm assembly or the support member , the load balancing device being configurable to exert a force to counteract a load exerted by the telescoping arm assembly and any attached monitor (M); and a cord storage device positioned at least partially within at least one of the telescoping arm assembly or the support member , wherein the cord storage device is suitable to wind and unwind the at least one cord (C1, C2) from said supported monitor as the first and second telescoping members are moved toward and away from each other, wherein the cord storage device comprises a fixed pulley and a movable pulley about which the at least one cord (C1, C2) can be stored, and wherein the movable pulley translates relative to the fixed pulley as the first and second telescoping members are moved towards and away from each other, characterized in that the fixed pulley and the movable pulley are each configured to store a first cord (C1), a second cord (C2), and a load supporting cable (C3), with said first and second cords (C1, C2) being part of the at least one cord. <EOS>
