How to Disassemble a Desk Chair

Turn the chair upside down and rest it at an angle on the floor with the seat supporting the chair. Remove the casters. Casters are the parts that include the wheels; they attach either with screws or by the insertion of a metal or plastic post into holes in the bottom of the leg base.

Unscrew the screw bolt holding the leg base to the main chair post. If the screw bolt is tight, squirt the bolt with a light spray of household lubricant. According to Blue Hen Office Furniture, you should give the lubricant about 5 minutes to saturate the bolt. Use a wrench to twist the screw bolt to get it started. Use a screwdriver to remove the bolt. In some instances, there may be an accessible nut instead of a screw bolt. Loosen the nut and the screw bolt will come free inside of the chair post.

Remove any protective cover or cylinder by sliding it off of the chair post. These coverings are usually plastic sleeves or expandable plastic sleeves.

Unscrew the chair seat foundation from beneath the desk chair seat. This is usually steel. Remove the desk chair seat. Once the chair seat has been removed, usually any seat adjusting lever or mechanism will fall free. There may be a screw securing part of this mechanism beneath the desk chair seat. Unscrew any screws that may be present.

Slide the chair post from the chair seat foundation.

Unscrew any desk chair armrests that may be attached to the chair seat foundation, the under edge of the chair seat or the back of the chair seat back.

Use a screwdriver to unscrew the seat back support arm from the chair seat foundation. The seat back support arm is the support holding the seat back to the chair seat. This often has a rubber or plastic sleeve over it that will slide off when the support arm is removed.
