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 without rear feet extending backward — good for tight spaces. A T-frame has feet extending in both directions from the center column — more stable but rear feet extend away from the wall. H-frames add a horizontal crossbar at floor level for maximum stability. T-frames are the most common commercial standard. At OfficeFurniture2go.com, product specs indicate frame type — call 1-800-460-0858.
