pivotal seat?

i have a pivotal seat but how do u take the seat off? do u slide it to the left or right??
look at my bike check if that info above is bad

There's a bolt inside of the seat.
On top of the seat there should be 2 flaps like a door or something else .
Inside there's an allen key bolt. The size should be a 6mm allen key. You undo it and the seat should come off.

you take it off the same way you got it on
