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

Frame geometry is a specification with direct implications for stability and workstation ergonomics at OfficeFurniture2go.com. Our C-frame configurations (inverted-L foot) maximize clear legroom beneath the desktop—preferred in ADA-compliant installations and for users who need to sit very close to the desk surface. T-frame configurations balance legroom and stability, making them the most common specification for standard commercial offices. K-frame and box-base designs are reserved for heavy-duty applications—our widest desks (72"–80") and triple-monitor configurations typically require K-frame bases to prevent racking under load. Our specifications team can recommend the correct base geometry for your installation. Call 1-800-460-0858.
