What is the practical difference between electric and pneumatic sit-stand desk mechanisms?

Electric sit-stand desks use a motor-driven lead screw to raise and lower the surface at the press of a button — hands-free and precise. Pneumatic (gas spring) desks use a pressurized cylinder that lifts the surface when you unlock a handle, relying on the spring tension to assist raising; these are typically single-leg converter designs rather than full desks. Electric full desks carry higher weight capacities (150–330 lbs surface) vs. pneumatic converters (typically 35–50 lbs).
