How does the weight on a sit-stand desk affect motor performance?

Electric sit-stand desk motors are rated for a specific load at full extension — typically 150–330 lbs depending on the motor tier. Operating a desk consistently near its maximum weight rating causes motors to work harder, generating more heat and reducing motor life. Keep loaded weight at least 20% below the maximum spec for longest motor lifespan. Dual-motor desks handle heavy loads more reliably than single-motor units of the same stated capacity.
