What is the difference between a T-frame and a C-frame on a sit-stand desk?

A C-frame has an offset column with feet extending in only one direction, which allows the desk to sit flush against a wall without rear feet sticking out behind it — useful in tight spaces. A T-frame has feet extending in both directions from the center column for better stability, but requires a few inches of clearance at the back wall. H-frames add a horizontal crossbar at floor level for maximum rigidity. T-frames are the most common commercial standard.
