Is the joint between the lumber support piece and the seat visible from below, or blind? If blind, the joint could be internally wedged, aka hell tenoned. If that is the case, then the parts are not intended to come apart, but could be loose all the same. If a through tenon was used, and you can see the end of the tenon clearly under the seat frame, and there are no wedges, it should be removable by tapping the seat frame member down.

The tenon is blind and not through the seat. The top of the lumbar support has a blind tenon and is connected to a cross piece and the cross piece is connected to the chair back uprights. It seems like things were m&teed then held together with a mild glue. I think Brian called it "hide" glue as in animal hide?
I tapped the chair seat and an eighth or so gap revealed with out too much trouble.
Thanks for the post up Chris.

They didn't use hide glue in old Chinese pieces, but either a fish-based glue or simply wiping the joints with lacquer. Hide glue is an acceptable substitute in most cases however.

Interesting, I'm thinking laquer because the tenons have a sort of shiny crunchy kind of film on them which does remind me of that.
