I've never given this surprisingly sturdy old Louis XV-style chair much of a chance to get comfortable in its own skin. I keep re-upholstering it. Since the chair is small and doesn't require much yardage, I can indulge in fabrics that would be too expensive for me on a larger project. (Today my current fabric obsession is still KWID's "Imperial Trellis" in Citrine.)
Although, I have to admit that sometimes I think this style chair looks its absolute best upholstered in a simple solid, like Mary McDonald's brown side chair below, photographed by Melanie Acevedo for House & Garden, November 2001.
