As you face the stage from your seats, lower number seats are on your right.
For traditional end-stage concerts at the Toyota Center, floor sections A, B and C are closest to the stage. These sections typically have between 12 and 16 seats each, with seat 1 on the right aisle as you face the stage. In section A, seat 1 is farther away from center stage than high-number seats.
For most concerts at the Toyota Center with an end-stage layout, the first three floor sections - A, B and C - typically have about 15 seats per row. When looking at the stage from Section C, seat 1 is closest to the middle of the stage. Therefore, seat 12 is on the far left side of the section.
While the proximity to the stage makes these a desirable choice, your actual view of the stage might be somewhat disappointing as you won't have a desirable head-on view.
