This pair of English made bergère chairs, made in the  late 18th Century or possibly early 19th, had been substantially  altered, the gilded frames damaged and the upholstery poorly executed.  The standard of the frame construction is good but they had been  re-gilded without interlagio over the frame joints  and there was much  consequent cracking in those areas with deterioration of the gilded  surfaces which were fairly knocked about overall, down to the bare wood  and, in places, beyond . Unlike the right-hand picture these chairs were  built to show the two vertical members and horizontal rail of the back  which were gilded on their rear surfaces and sides. This was not  apparent until the upholstery was removed. The previous gilder had taken  the vertical members through the gesso stage followed by the  upholsterer who covered them up. Research found pictures of the  correctly exposed and gilded back frames and this is the route we   suggested and which was approved. The frame pictured below has been  re-gilded, this time with interlagio support and the two vertical  members and one horizontal member are gilded on the rear and sides. This  is plainly to be seen in the first sketch below.
 Interlagio  is a thin fabric covering applied to sound joints during the  application of gesso. Traditionally silk is used but a fine lawn or  sea-island cotton is just as good. Beware of using a material past its  best which will be weak and liable to part as the joint flexes. The  interlagio is pasted over the joints with a first coat of thin gesso and  subsequently covered with thicker gesso as work proceeds.

Above all the  interlagio must not be so near to the surface that when the gesso is cut  back or carved (also known as cutting) that it suddenly appears—so go  for a really fine material. The chairs were water gilded and the  highlights burnished.
A surprise was the discovery that the cushion covers  are of hand-stitched kid leather and presumably original.  Bert, had  come across  five or six examples of white kid being used for cushion  cases and quoted that King George II had a travelling bed with a ticking  of kid leather. Next comes the upholstery which, in view of the  restoration of the back panels, required a new approach. and I asked  Bert to write a piece on the proper way to do this which now follows :
Upholstery of Bergère Chairs
Below are two sketches showing how the outside back  panel, framed between the two gilded vertical members, is placed and the   method of fixing a length of cane 10mm  above the seat platform to  allow the various stuffing covers to pass underneath before tacking to  the top of the seat rail.


The top sketch shows how the back of the chairs will  look with the seat cover coming through under the horizontal rail. The  centre panel upholstery meets the seat upholstery snugly showing no  light.
Many thanks to Bert for these two very clear sketches  which should be useful references to any reader faced with the same  problem.
