Seated tickets are a different type of ticket type. They are linked to a seating chart.
Because of this, there are some differences between seated tickets and other types of tickets.
Seated ticket quantities are controlled by a mixture of the categories on your seating chart and the ticket type quantity. If you set a higher event/ticket type quantity than in your seating chart, you can't sell more seats than in your chart.
Example 1: if I have a seating chart with 100 general admission seats, and a general admission seated ticket type with a quantity of 50, I will only be able to sell 50 seats.
Example 2: if I have a seating chart with 100 general admission seats, and a general admission seated ticket type with a quantity of 150, I will only be able to sell 100 seats.
To hold seated tickets, it's a bit different from the hold function for other ticket types. Please see: How to put seated tickets on hold.
