An example gas lift cylinder removal device described herein includes a collar assembly having a guide pin, a set screw, and a lead screw. The example cylinder removal device is disposed on a gas lift cylinder and provided proximate to and below a seat plate assembly of an example task chair. Operation of the gas lift cylinder removal tool from a first position to a second position provides a mechanical advantage to impart an upward force on a bushing of the seat plate assembly, thereby displacing the cylinder from the seat plate assembly. An example task chair having the gas lift cylinder removal tool is described herein comprising a support surface, a seat plate assembly, and a base assembly, the seat plate assembly including a bushing, an upper plate and a lower plate.

A swivel chair device having an ascending and descending function. The swivel chair device comprises a support pipe (1), a shaft sleeve (5), a spline pipe (6) and a telescopic cylinder (7). The shaft sleeve (5) is fixedly arranged in the support pipe (1). The spline pipe (6) is arranged in the support pipe (1), the bottom end of the spline pipe (6) being higher than the bottom end of the support pipe (1), and the top end of the spline pipe (6) being fixedly connected to the shaft sleeve (5) so as to be connected to the support pipe (1) to form a non-rotating body. A rotary reset mechanism, which elastically connects the telescopic cylinder (7) to the spline pipe (6) for driving the telescopic cylinder (7) that has been rotated at any angle to be automatically reset, is further arranged in the spline pipe (6).
