I don't know how to bring up the wheelchair up the stairs

And the wheelchair has not been used at all since it was bought 5 years back and it's just taking space on the first floor. I'm planning to just bring it to the room upstairs where we have bigger space. And so I don't know if I can bring it up myself since I know it can be dangerous as the stairs are kinda steep and the wheelchair is quite heavy also. And I have no one who would help me to carry the wheelchair all the way up. But I want to clear the first floor of anything that are just eyesore and blocks the way.
