Very smart move! Eliminates the most common FPV injuries
I'm a bit sour on those very common sling-arm folding chairs, but found a more robust alternative, the Timber Ridge Director's Chair, available at COSTCO in the US. Has solid armrests and a small foldout side-table. I absolutely love these, very lightweight, sturdy, height like a kitchen table chair, folds flat. I have a half dozen. They even have a heated version, of which I have 2.
A little more expensive, but worth every penny, especially if your a bit older and don't like climbing out of the more sling-like chairs. I'll bet you can find them in the EU too.
