Hello from Portland, OR...
I have an '04 Safari 25. I needed an additional chair to pull up when eating. There is no dinette in my trailer... a table in front of part of the sofa. Anyway, I bought a BABA side chair in beach wood from Design Within Reach here in Portland, It works great... looks great too. When not using it at the table, it sits just inside the door to the right... up against the wall. It is sitting on carpeting and does not slide around at all. So I wonder if you really need to bolt them down. They have some really great chairs at Design Within Reach that would look great in an Airstream.
