Seat

The Seat is a component that controls other components. It costs 98 Scrap to load each seat, and you can set custom keybindings by clicking the Set keybindings button that shows up when you sit on the seat.

When you sit on a seat that is on someone else's Build Zone, you take damage and the seat automatically kicks you off.

Because there is no feature to block players from your build zones, players like to make seat killers that trap offending players on their build zone, eventually killing them.
