What is the main disadvantage of a two-person seat carry?

The main disadvantage of a two-person seat carry is that it can be challenging to maneuver through doors. In emergency situations, especially when rapid extraction is necessary, the design of the two-person carry can hinder the ability to navigate quickly through narrow doorways. Rescuers have to carefully align and adjust their positions to fit through doors, which may slow down the rescue process.

When moving a patient in an emergency, the need for speed and efficiency is critical, and struggling to get through doors can be a significant obstacle. This challenge highlights why it's important to consider alternative carrying methods that may allow for better maneuverability in constrained spaces.
