So I got big nulls in my room at 40hz and at about 80hz (mainly want to fix the 80hz). The image below is my listening room. Things to note is that at the far end of the room I cannot really place anything and the front wall is sloped (the green line indicates where the slope is) with a radiator on the right where I can't really put anything. Since I don't want my room to look like a studio I want to put bass traps in Ikea bookshelves etc. I also have no way to fix ceiling reflections.
In purple I've indicated possible places I can put stuff.

- On the bottom you see a bookcase I can put trapping material in (its about 30cm deep). I can also stick something to the side, because that's nicely out of sight.
- I can put a room divider such as Ikea Kallax behind my couch and fill it with material. This would be about 1.5m in height and can be about 30-40cm in depth.
- I can also put a bookcase next to the couch and fill that.
