Bent Seat Post

I just noticed that on my giraffe uni the top part has slightly bent. the bendage is at the bottom and since i havent ridden it in ages i dont know how long its been like that or how it got like that. i seem to ride it just normally and feels very normal but id rather get it fixed, but thatss my question, how do i get it fxed or do i have to replace it?

sorry, i mean not the seat post but what the seat post slides into its the big chrome pole at that runs from the middle of the uni to the top
.

cheap 'raffe frames bend easily, lay it on the ground and stand on it to straighten it out. You might need someone to hold it correctly orientated while you apply your weight.
