Date made? 3 Piece armchair setting

I bought these the other day - i thought they had a beautiful shape and I thought I would recover them and restore them. The lady I bought them from didn't know how old they were, I was wondering if anyone here could give me an approximation. I have a feeling they have been recovered previously. They have springs underneath the seat radiating out from a central point.
