one chair, four rooms

I save pictures of rooms I like and I was recently going through a few of my favorites and found one very similar chair in 4 rooms. I like the dark grey room with bright table and chairs and the way the room looks modern but warm. I like the second room because it's a little more cottage with modern touches, and I would love to have a cozy windowseat like that one day. The third room is pretty because it's so subdued, but then there's this one bright orange chair that stands out. I love lots of stuff about the last room, the ceiling-high bookshelves, with a ladder, and the red locker console. I need to start going to flea markets to find a chair like this.
