monstera advice? sits forward in front of pot

I’ve had this monstera for a few years and I would like some advice on how to support it more.

I have 2 moss poles, but as you can see in the first photo, it sits very forward out of the pot and is so heavy that it’s not very stable staying in the pot. I also have a rock in there bc it helped with manipulating the stems.

Is there a different/more stable pot I should be using? Or a different way I should place the moss poles?

I would like it to stand up a little straighter and be less unstable.

It lives in the spare room in front of this west facing window with the shades down, but I think it would look nicer if it was standing tall in a corner or somewhere where we can see the leaves thriving.

I water it every week or every other week depending on if the soil is wet (I have a moisture meter and I love it hehe)

Grateful for any advice 💚
