The Office Chair is a Bit Crooked

If the office chair is a bit crooked, you can troubleshoot and fix it using the following methods:

Uneven ground or worn chair feet are common causes. If there are height differences in the ground, you can use rubber pads to elevate the shorter chair legs or use an angle grinder or 80-grit sandpaper to sand down the longer chair legs, adjusting their lengths based on the chair seat as the horizontal reference. Alternatively, you can directly install adjustable feet and fine-tune their heights by rotating them to accommodate different ground surfaces.

Inconsistent chair leg lengths may result from manufacturing errors or long-term wear. You can address this by following the methods for adjusting chair legs to ensure all four legs are of equal length, allowing the chair to sit evenly.

Loose connecting components require a thorough check of the screws and bolts at the joints between the chair seat and legs. Use a screwdriver or wrench to loosen the screws counterclockwise, add a small amount of lubricant, and then tighten them clockwise, being careful not to overtighten. If the screw holes are worn, you can use toothpicks or thin wooden sticks dipped in white glue to fill the holes. After the glue dries, reinsert the screws to enhance the fixing effect.

Worn foot pads can cause instability at the bottom of the chair. If the rubber or plastic foot pads are severely worn or have fallen off, replace them promptly with new ones to restore the chair's stability.

Damaged frame structure is more common in solid wood chairs with mortise-and-tenon joints. Prolonged stress can cause the tenons to loosen, crack, or even break, requiring timely reinforcement. If necessary, contact a professional repair technician for assistance.

Damaged gas lift is the primary cause of sideways tilting in executive chairs. If you suspect a faulty gas lift, first lift the chair so that the feet are off the ground. Use a rubber mallet to strike the feet from top to bottom until you reach the rubber joint. When disassembling, first remove the feet, then turn the chair upside down and hold the gas lift while striking the base until it detaches. Finally, install a new gas lift. Be careful not to strike the gas lift directly to avoid damaging its internal structure.

Base failure requires checking whether the base is cracked or aged, or if the connections to the five-star feet are loose. If the base is damaged, replace it promptly with a new one to restore stability.

Wheel issues can also cause the chair to tilt. Place the chair upright and confirm that each wheel is in contact with the ground. Turn the chair upside down to inspect the wheels for signs of damage. If the wheels are bent or deformed, purchase matching new wheels for replacement. When replacing, pull out each caster directly. If you cannot do so by hand, use a flat-head screwdriver for assistance. Apply a small amount of spray lubricant to the sockets on the chair base. Use a rubber mallet to tap the new casters into the sockets. Finally, turn the chair upside down to test whether the new wheels are stable.
