Baby gate recommendations?

Question

I’ve seen gates that can affix to square Newell posts, but as you can see ours are square on the bottom and round where the top of the gate would be. Anyone else have a similar setup and a gate they can recommend?

Answer

We have one of these it could fold around the area

Answer

There's a couple Summer Infant gates that look like they'd work on Lowes.com (not sure if you have one where you are.)
