To remove the 5 star base:
1. To remove the five star base from the gas lift, turn the chair upside down. There are about one to two inches where the gas lift sticks through the five star base.
2. Use a hammer to hit the edge or rim of the gas lift while pulling out the five star base. Avoid hitting the metal clip in the center of the gas lift, as it will release the pressure needed in order to raise or lower your chair. The more you hit the gas lift, the more pressure will be released. After several taps, it will come right out.
To remove the gas lift:
1. To remove the gas lift from the seat plate, keep the chair upside down.
2. Use a hammer to hit around the area where the gas lift fits inside the seat plate while pulling out the gas lift. These two items are locked together by pressure; the more you hit the seat plate and pull on the gas lift simultaneously, the more pressure will be released. Eventually the two items will separate.
To remove the seat plate:
Use the allen wrench that came with the chair to unscrew the seat plate from the seat cushion. Make sure to keep the black plastic spacer attached to the seat cushion.
