A variable height workstation system includes a base, a variable height platform, a lift mechanism, and a sensor arrangement. The lift mechanism is configured to move the variable height platform within a range of motion between a fully lowered position and a raised position. The sensor arrangement is operatively connected to the variable height platform. The sensor arrangement is configured to sense the position and movement of a user on, above and around the variable height platform for outputting data to determine how the user is positioned on, above and around the variable height platform in comparison to a predetermined target position.

A height adjustment system for a delivery table or the like having a table top supported upon a height adjustable column with an assist cylinder. The system includes an actuator assembly to operate the assist cylinder from manual actuators, such as paddles, located approximately in four corners of table top. The system may include a pair of paddle assemblies mounted under the table top on opposite sides of said assist cylinder. The paddle assemblies may be coupled to the assist cylinder by a linear linkage that translates pivotal movement of a paddle into linear movement sufficient to actuate the assist cylinder. The linear linkage may include a straight drive rod coupled to one paddle assembly and an offset drive rod coupled to the other paddle assembly. The linear linkage may also include a pivot arm to reverse movement of the offset drive rod.

A height adjustable desk or table comprising a desk or table top, and a frame with spaced apart legs for sup-porting the desk or table top, wherein each of the legs comprises a movable upper portion and a lower stationary portion, and wherein a first cable is guided via first guide means connected with a lower end of the movable upper portion of the first leg via second guide means to a lower end of the lower stationary portion of the second leg, and a second cable is guided via third guide means connected with a lower end of the movable upper portion of the second leg via fourth guide means to a lower end of the lower stationary portion of the first leg, wherein each of the legs comprises a gas spring, and wherein for each gas spring the upper portion of the gas spring is arranged to be up-and-down movable portion of the leg and the lower portion of each gas spring is arranged to be the lower stationary portion of the leg.
