Repair Methods for Broken Office Chairs
The repair methods for a broken office chair depend on the type of chair. Here are common situations and repair steps:
I. Repair of Reclining Office Chairs (Mostly Swivel Chairs with Wheels)
Inspect the Wheels Place the chair upright and upside down to check if the wheels are level. When upside down, examine each wheel foot for bends, breaks, or signs of wear. If there is damage, purchase matching wheels: contact the manufacturer for the model number to order, or take the old wheels to an office supplies store to compare the shape and size of the wheel axles, ensuring the new wheels have the same diameter and length as the original axles.
Remove the Old Casters Pull out the snap-in type wheels directly. If they are stuck, insert a flat-head screwdriver into the gap between the wheel foot and the chair's contact point, and slowly pry back and forth until it is pulled out about 1 centimeter, then pull again. For a very small number of casters fixed with screws, use a screwdriver to loosen the screws and remove them.
Lubricate and Install Spray a small amount of WD-40 lubricant (or apply a pea-sized amount of petroleum jelly) into the chair base socket. Use a rubber mallet to tap the new caster into the socket, ensuring the caster rod is aligned with the base. First, give it a light push to confirm the locking position. If it is not in place, tap gently near the base of the stem to avoid deformation.
Test and Troubleshoot After placing the chair upside down, sit on it to test if the wheels roll smoothly and evenly. If it is still tilted, check if the seat plate is cracked or deformed, and replace it if necessary.
II. Repair of Wooden Office Chairs
Adjust Leg Length Differences Measure the distance from the bottom of the shortest leg to the ground. Select furniture nails with a thickness of 0.32 - 0.64 centimeters and nail them into the bottom of the leg, or sand down the longer legs to make them the same height as the others, ensuring the chair stands steadily on all four feet.
Re-glue Loose Joints Place the chair upside down, remove the screws that fix the legs and mark their positions. Use a chisel to remove the old glue blocks from the joints, and sand the remaining glue and the exposed ends of the chair legs with 120-grit sandpaper. Apply wood glue along the joints and legs, reinstall them, and tap them tight with a rubber mallet. Stand the chair upright and place heavy objects (such as books) on the seat for more than 24 hours until the glue is completely dry.
III. Repair of Sofa-style Office Chairs
Remove the Seat Cushion and Chair Legs Place the chair on its side, use an electric drill to remove the screws on the side of the bottom of the seat cushion, and take off the seat cushion. Use a rubber mallet to gently tap the inside of the back legs to separate the chair legs from the seat (if there is no rubber mallet, wrap the chair legs with thin softwood and then tap).
Reinforce the Mortise-and-tenon Structure Use a glue dispenser to apply wood glue around the tenon head and round nails, ensuring the glue covers all contact surfaces. Reassemble and gently press on each joint, and let it sit until the glue cures.
