Usually, climbing stairs once is exhausting, especially for some disabled people and those with limited mobility. For many people, going up and down the stairs has become a headache. Usually, young people need to go up and down the stairs with their backs on their backs, and then take a wheelchair. It is okay when there are family members, and this problem can be solved.

It is inconvenient to carry, it is inconvenient to go out, and it takes up too much space in the room, etc.
