Although office chair designs across brands vary in shape and size, most share basic similarities that make it easy to recognize the points of attachment. In addition, chair manufacturers often use the same types of hardware—screws and bolts—to attach the pieces. As a result, you can quickly disassemble most chairs without difficulty.
Items you will need
Mallet (rubber head)
Screwdriver set/electric screwdriver
Place chair on its side and pull each wheel from its slot in the chair base. If your chair has wheels that seem to lock into the slot, try the following to remove the wheels:
1) Look for a small lever or tab on each wheel and press or pull it to see if it unlocks the wheel from the wheel slot. 2) Put on a pair of gloves with grips and try to pull or twist the wheels from the slot. 3) If all else fails, use a rubber mallet to hammer the wheels loose.
Remove the chair’s armrests (if they can be separated from the chair or chair seat). Removable armrests typically slide into slots in your chair and/or attach via screws or bolts. Use a flat-head or cross-head screwdriver or Allen wrench (also known as a hex key) to unscrew and remove.
Pull the chair apart (if applicable with your model) and then pull it from the base. Remove any screws or bolts attaching the chair back to the seat unless the chair is a single unit with the back and seat permanently attached.
If the chair is a single unit, check if the hydraulics that help the chair to lift (if applicable with your model) are part of the chair assembly. If the hydraulics are not attached, pull the chair away from the hydraulics, set it aside and then remove the hydraulics--including cylinder--from the chair’s base. If the hydraulics are attached, look under the chair base for any screws or bolts, remove any hardware as needed, and then lift the entire seat and hydraulic assembly from the chair's base.
Bag any small hardware pieces and then box all of the disassembled chair pieces for moving or storage.
If the hydraulic cylinder has become stuck in the tube, lightly tap the bottom of the cylinder with your rubber mallet to dislodge it from the tube.
