I am wondering how to tell if a cushion replacement is needed or if the actual springs/seat are worn out on a chair? I picked up a used Hancock and Moore Richmond chair for cheap that is in pretty good condition after cleaning it up and repairing a crack in one of the legs, but the seat is noticeably worn down when you sit in it, it sinks much further than it should and does not feel very padded. Pressing directly on the deck underneath the cushion it still feels fairly ok and I don't have any soft spots, but I don't really know what I am looking for either. I can even sit in it without the cushion and it feels like it supports my weight fine. Before I spend the money to replace the cushion to hopefully restore the chair to its full comfort, is there anything else I can check to make sure it is just the cushion?
