Chair Modifications

The chair has a temporary covering now and some foam. The thickness of foam was tested and about an inch seems to be the best thickness.
The covering is a smaller piece of fabric than is necessary, but it's just a scrap piece so I added another to give an overall covering.

The height adjustment has so far resulted in a 10mm reduction in height which had a large effect on the feel of the chair. It looks like even a few mm makes quite a big difference to the feel of the chair. <Maybe I should have measured the chairs we looked at a bit more accurately...
