Replacing a cylinder

Step 1: Turn the chair or stool upside down where the base of the chair with the wheels is facing the ceiling.

Step 2: Grab the cylinder with one hand and hold it so the chair is slightly raised off of the table or floor. Then using a rubber mallet, hit the seat of the chair and/or the control of the chair. Do not worry about hitting it too hard; you will not hurt the chair. If needed, spray a little lubricant like WD-40 in the crack where the cylinder meets the seat.

Step 3: Once the seat is removed from the cylinder, turn the base back over to where the wheels are facing the floor. Then, grasp the cylinder in one hand and hold the base slightly off of the table or floor and hit the legs of the base to release the pressure fit. Again, if needed, spray a little lubricant in the crack where the cylinder meets the base. This may take more effort depending on how long the chair has been in use.

Step 4: To replace the cylinder, place the replacement cylinder in the base and the seat on top of the cylinder, then sit on the chair carefully to engage the pressure fit.
