I wonder why noone simply vandalizes it.

It would be funny if someone with an angle grinder came to the public bench and cut off the "arm rests" that you can't even rest your arm on because their only purpose is to prevent homeless from sleeping on a bench that literally noone uses at night anyway.

The Camden bench looks like it should be possible to design a nice wooden seating surface for it that is just placed on top with no additional fastening required. Having all these edges on top will help keeping it in place.
