A low seating bench?

A chair in the corner?

I was thinking about that but I don't want my children sitting by glass or using glass to lean on

A large urn in the corner? That might keep them away from glass.

how long have you been living here, as it feels like a new problem.... i understand you dont want a bench or something that could be stood on.... kids grow up fast and it wont be a problem forever. leave it as it is if you feel that anything would be an attractive nuisance.

A nice plant

Personally, a chair and ottoman would be my preference but if that's a worry due to kids, I would put a nice and substantial plant to the left.

I'd be looking more at the wall behind though. Is that your entry? I would put in some sort of bench down there with some large scale artwork above and then the glass railing wouldn't feel so stark

good idea..... something more dynamic than the mirror would improve the view through the glass.

If the room works functionally, I wouldn't add more furniture (it's hard to tell without more photos).

If you want to visually add interest, one option is to remove the small mirror from the opposite wall and put a large artwork on that wall. You can see it from both rooms that way.

it looks to be the entrance to a split level house...coming in mid floor, stairs up and stairs down.

so the trick will be to have something big enough for upstairs without overwhelming the landing.

I have an open layout, it's my living room but the area downstairs is my entry

Hah, seems a bunch of us were coming to the same sort of conclusion on the opposite wall :-)

Hello Sasha! What a lovely space. It's very bright and open which I think is important to maintain. One or two accent chairs and a glass top end table would be appropriate. I would suggest chairs with a relatively minimalistic style, but have a subtle fabric pattern that is somewhat modern. Keeping fabric colors and finishes light will help maintain a sense of openness. A glass top end table with slightly curvy metal legs would blend well with existing finishes and contemporary lines. Also, a glass vase fresh flowers on the end table would warm the space nicely. Have fun and good luck with your project!
