I’ve been trying for years to find a lamp that would go in the corner (behind blue arm chair). Please excuse the dying plant 
The corner is not really a corner, so the lamp would have to go right behind the chair. I like the idea of an arching one but don’t think it would work as we’d end up head butting it when standing from the chair. I’ve tried a few standard, straight lamps with a lampshade but they seem too short to me and only finish a little higher than the back of the chair, which looks a bit weird 
Any ideas what might work in this corner? Thank you
