How do I prevent a U-shaped desk from racking or becoming unstable over time?

Racking (lateral wobbling) in a U-shaped desk is usually caused by loose cam lock connections or missing back panel support. Tighten all cam locks and connector bolts annually. If the desk has a back modesty panel, make sure it's properly seated — it provides diagonal stiffness. Ensure the desk is on a flat, level floor; adjust leveling glides if the floor is uneven.
