Fans seated in the baseline sections on the lower level are a big reason why the Warriors have a huge home-court advantage. Some of the loudest and most passionate fans call these sections home.
While 100 level sections behind the basket are usually to be avoided, these aren't as bad as they are in other arenas. The worst seats are usually located behind the basket in the first ten rows. At Oracle, these seats don't exist and the North and South tunnels occupy these spaces instead. Never-the-less, it's a good idea to choose seats in a section like 120 or 123 where you won't be directly behind the hoop and you'll have a better sightline.
Unless your goal is to sit as close to the floor as possible, aim for seats near the top of each section. These seats rise more steeply than the lower rows which makes it easier to see over fans seated in front of you. The entrance tunnels are also located at the top so you'll be just a few steps away from amenities.
Fans with mobility issues will want to avoid lower rows where fans in the front row have as many as 30 stairs to climb when getting in and out of their seats. For those in wheelchairs or needing assistance, accessible seating is available at the top of 107, 108, 121 and 122.
