Many office chairs are self-assembled, requiring only screws to put together. Over time, the base on an office chair may wear out, causing the chair to separate from the mounting bracket. The following guide provides information on repairing a broken office chair. Turn the chair on it's side, and inspect the holes where screws attach to the bottom. If the screws were stripped, larger screws will be required to remount the bracket. Before installing larger screws, inject superglue into each screw hole. This will help prevent screws from slipping in the future, and will help ensure a safe office chair.
