What would be the simplest technique for securing an angled backrest on a sofa frame like this, with no support struts? (Apologies if that's not the correct term. I'm sure there must be a correct word, but I'm not sure what it is, as I'm an untutored newbie! Gussets?)
Presumably, it's not just a case of screw and glue?
