My understanding of "Mission," with it's positive overtones in the antique world denoting craftsmanship and materials, is that it is something from the first half of the 20th century, usually using quarter-sawn or at least solid oak, with strong, simple lines and built to last for centuries.
I do not get any of that from this photograph. This seller is using the term very loosely, in the same way that people throw around the term "antique," not knowing or caring that it should be used with care, to define objects within certain parameters.
"Mission style" or "Mission influenced" might be better terms. Like Wull said, I would see it in my garage or basement long before I'd allow it upstairs.
