The new Levi's Stadium in Santa Clara is expected to be one of the most technologically advanced stadiums in the country. But it's a little piece of plastic that may put it over the top.
Fans won't just get cup holders when they arrive at their seats, but also hooks.
The 49ers have added specially designed hooks to the back of each seat, so fans can hang their stuff off the ground.
The seat manufacturer, Camatic, told the Niners it's the first time they've ever received a request like this.
"Since they have been installed,” 49ers project executive Jack Hill said, “we’ve had a lot of positive comments from the fans."
