A George III Campaign Chair with a wavy ladder back design and X-frame legs. Aside from the folding action of the legs, this chair is comparable to a Naval Chair.
The seat frame on both locks the legs into position. On a Naval chair it is hinged at the back to lift up but on this chair it is hinged to the front with 2 pins to the back to lock the seat into position. The seat frame looks to have been restored at some stage, although judging by the quality of tight caning it was probably over 100 years ago. At this point it is likely that the fixing bolt was also replaced to the back of the seat. The back has iron hinges with removable pins to allow it to fold forwards. It also has inset brass hinges to the front. They may have been added at the time as the seat repairs to further strengthen the chair, or they could be original; it is very hard to tell. They have certainly been on a very long time. To fold the shaped arms, you simply lift them off their posts and they drop parallel to the back. The posts also drop on their pins for packing. The legs have a gentle, curved sweep and terminate in a scroll with a wedge to the front.
This chair may have been through a workshop at some stage but given its purpose and the fact it can be considered an early campaign chair this is perhaps to be expected. We have not encountered a similar chair before. Circa 1780.
