Office Chair and Stool Repair

Admin October 10, 2026

Office chair and stool repair requires targeted handling based on different types of damage, as detailed below:

Repair of cracks in wooden boss's stools: If a crack appears in a wooden boss's stool, first remove the wedges and clean the base area. Then, squeeze in woodworking glue. For small cracks, if the glue has difficulty flowing in, use a blow nozzle or straw to blow the glue in. Next, perform clamping operations. When glue beads seep out, wipe off the excess glue and let it sit for 24 hours to allow the glue to reach its maximum strength. After that, prepare to make butterfly patches. First, determine their size, drill large holes, chisel out recesses, and smooth them out. Apply glue and hammer in the butterfly patches, and also repair several areas at the bottom. After the glue dries, remove the clamps, remove the excess parts, and sand them smooth. If the tenon of the stool leg is severely deformed, it can be repaired by mixing quick-drying glue with sawdust and then inserting wedges into the gaps before leveling.

Repair of minor abrasions on the back of leather boss's chairs: When minor abrasions appear on the back of a leather boss's chair, first use a multi-purpose cleaner to clean the damaged area, removing surface dirt and impurities to prepare for subsequent repair work.

Repair of an office chair tilting to one side:

  • Check the wheels: Place the chair upright and confirm that each wheel foot is in contact with the ground. Invert the chair and check each wheel foot for signs of damage. Casters may bend or break due to uneven weight distribution, manufacturing defects, or general wear and tear. If the chair is placed on an uneven surface and the wheels do not all touch the ground when unoccupied, it will tilt to the lower side when someone sits on it. If damaged wheels are found, you can purchase a new set of matching wheels, contact the manufacturer with the chair model to order matching wheel feet, or remove the old wheels and take one to an office supplies store to find a matching replacement set, paying attention to matching the shape and size of the wheel axles. If all wheels are in good condition and the chair is placed on a flat surface, you can skip checking the seat plate.
  • Remove the casters: Hold the caster wheel with one hand and the bottom of the chair with the other hand, and pull firmly. If the caster foot cannot be pulled out, insert the blade of a flat-head screwdriver into the small gap between the wheel foot and the chair, and use the blade as a lever to operate it back and forth slowly. Pull out about 1 centimeter and then pull on the wheel foot again. A very small number of casters are fixed with screws. If you see a screw head, use a screwdriver to loosen the screw and remove the caster.
  • Apply lubricant: Apply a small amount of spray lubricant, such as WD-40, to each socket on the chair base. Insert the straw into the spray nozzle and insert it into each socket for a quick spray, about half a second per socket. If you do not have a lubricant spray, you can apply a pea-sized amount of petroleum jelly to each wheel axle.
  • Install the casters: Use a rubber mallet to hammer each caster into its socket on the chair. Align the caster rod with the intended base, and push it gently with your hand. If it does not seat properly, gently tap the caster with a rubber mallet until the rod is fully inserted into the base. If the caster design allows tapping near the base of the stem, do so to reduce the risk of deforming or breaking the new caster.
  • Test: Invert the chair to test the new wheels. Sit on the chair. If it rolls smoothly and evenly and no longer tilts to one side, the repair is complete. If it still tilts, continue to check the seat plate for damage.
