How does exceeding a sit-stand desk's weight capacity affect performance?

Weight capacity is a BIFMA-tested specification, not a marketing estimate, and OfficeFurniture2go.com specifies our frames well above typical operational loads to provide a genuine safety margin. Per BIFMA X5.5 methodology, our frames are tested at 1.5× rated capacity to verify structural integrity. Operating consistently at or above rated capacity—especially with cyclic lifting—will degrade motor thermal performance and may void the warranty. A common error is calculating screen weight only and omitting monitor arm weight (5–12 lbs), CPU weight (15–25 lbs), and desk accessories. We recommend targeting no more than 70% of rated capacity as a practical operational maximum. Call 1-800-460-0858.
