What is the difference between T-frame, C-frame, and K-frame sit-stand desks?

T-frame desks have a crossbar connecting the two lifting columns at the back, forming a T-shape when viewed from the side — they offer good lateral stability but the rear crossbar can limit cable routing. C-frame (or L-frame) desks have the crossbar at the front or a side offset, leaving the rear open for cable management. K-frame desks (less common) use a diagonal brace for rigidity. T-frame is the most common in commercial desks; C-frame suits cable-heavy setups.
