There are stairs to the basement on the first floor, and the stairs are behind the sofa. Should the handrail between the stairs and the sofa be separated? How to make the space not seem small?

Putting the sofa in front of the stairs has some disadvantages:

Security risks. Generally speaking, children at home basically jump around on the sofa. Restless. It is dangerous to jump over the back of the sofa. Even if there is a screen, it is unstable. Of course, if it can't be changed, at least a screen should be added, but the stairs will be very narrow.

Feng shui is not good either. In feng shui, people pay attention to having a backrest and a backer. Therefore, the back of the sofa in a general family should be a wall or a three-dimensional screen. There is no wall at the back, but it is still a downward stair hole. The back is empty, and it's still a hole. Bad luck.

If so, there is no way to change the position of the sofa. Consider something like the picture below. Add a long cabinet to the sofa and stairwell. So it's not easy to drop things.
