It is well-known that pews are a Protestant invention.
I thought what you said above about removing pews and putting in a rood screen was a joke or sarcasm.
Are you serious?
The high-back pew may very well have started in Protestant churches - ancient Catholic churches tend to have stools or benches. But so what? The Advent Wreath probably comes from Lutheranism, but I bet many traditional Roman Rite churches also use it. The Church has long baptised and incorporated things from outside the Church.
