Yes! You can "Mix & Match"! Just stay within the same "families" of desks as we did here with a Standard Rolltop (and adding a PLUS4 height option to clear a tall audio console) paired with a High Rise Standard Rolltop (with a NOUPPER option to house video monitors). Both desks are 34" front-to-back since they are in the "Standard" family of dimensions. A PASSTHRU option between the securely bolted-together mated internal sidewalls of the two desks provides comfortable legroom.
