Wing Chair: This is an example of a wing chair. These chairs have high backs and give good upright support for the back. They have arm rests and legs. There are also side pieces that come out from the back of the chair, which were originally intended to protect the sitter from any kind of draft.
This bay window has 3 separate openings with relatively wide molding between each, If you have enough depth, the roman shades can be mounted inside each window opening. In this case it looks like the windows were too shallow and the shades had to be mounted above the windows. The wide molding between windows covers the gap between the shades.
