This is the Carlo Mid-Century Chair at West Elm. You can probably guess how it got the name, as it positvely oozes the style of that era.
Yes, unashamedly mid-century / midcentury in look and taking particular inspiration from Italian furnishings of that era. Strong lines, angled arms, a pitched back and of course, those wonderful cast metal legs with a brass finish. I think the latter is definitely the killer feature here.
The one finish, described as a twill granite and a price of £599 from West Elm.
Note that you can pick up West Elm designs at John Lewis too.
