Known more for its amenities than outstanding views, Box Seats are located behind the baskets on either end of the court. For Wizards games these amenities include in-seat wait service with some complimentary food and beverages.
If you care more about a great view than great service, consider seats in a different seating zone. The basket is highly disruptive and will limit your view of at least part of the court. Additionally, these seats have very little rise to them, making it difficult to see over fans seated in front of you.
