Office chairs come conveniently in a small, flat box, and you can assemble one in less then 20 minutes. You will probably use your chair for quite some time before you must move it or take it apart to get it out of a room. Taking an office chair apart is just as easy as assembling one; you just must remember how you took it apart when you want to reassemble it. The best way to take apart an office chair is to read your original instructions for building it, but start with the last step first and dissemble it rather than assemble.
Unscrew the setscrew holding the wheel base to the cylinder shaft. Take the wheel base off the shaft.
Pry each wheel out of the quick-tache connector on the wheel base with a flathead screwdriver.
Unscrew the two setscrews holding the cylinder shaft to the base connector under the seat of the chair. Lift the seat off the shaft.
Unscrew the 90-degree angle connector holding the back and seat of the office chair together. The angle connector should have 4 bolts in the seat base and 4 bolts in the back rest of the office chair.
Unscrew the arms off each side of the seat base.
