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

A C-frame (offset column, feet extending one direction) allows the desk to sit flush against a wall — good for tight spaces. A T-frame has feet extending in both directions from the center column — more stable but rear feet extend backward. T-frames are the most common commercial standard.
