The visiting team bench at Oracle Arena is located just in front of Section 2, and part of Section 1. For the closest seats behind the Celtics bench, look for higher numbered seats in Section 1 (seats 14-16), or any seat numbers in Section 2. There are a total of 5 rows in each of these sections, running from Row A1 (closest) to Row A5.
Section 5 will also be located very close to the Celtics bench, but will have more of a corner view than in Sections 1 and 2. Section 5 has a total of rows also, running from Row A1 to Row A5.
