I would like thank to @Govindas who been using this skript on his server for helping me to add new features to this small skript:

Added a check for already sitting
"You are already sitting!"

Added a check for player velocity,
"You cannot sit while you have velocity!"

Added a check for player's ground level,
"You must be on ground to be able to sit!"
