What Do You See When You Look At This Collection of Rooms?

I'm curious about what people besides me see when they look at my room collections. I pulled these the other day for a reason....Can you tell what they all have in common? I bet you can, but thought I'd ask. I'll tell you at the end what I was thinking.....

So did you guess?
I'm sure these rooms have other things in common, but what I've been noticing a lot lately is that floor lamps seem to be making a big comeback. I'm seeing them everywhere, are you? Honestly, I didn't use to love them, preferring instead a table with a lamp on it. After having decorated so many rooms, though, I've become a bigger fan of floor lamps, for a couple of reasons. First, every room needs some tall items, and these can be taller than some tables with lamps, sometimes giving the height that a bookcase would. Also, they are so narrow and take up almost no space, so they work really well when you need that height aesthetically, or simply need light, but don't have room for a table and lamp. Finally, I am a big fan of symmetry, and as some of these examples show (especially the black and white one), you can get perfect symmetry with two floor lamps on either side of a sofa, for example. I just love the way it looks.
Here are some affordable floor lamps on sale today (which prompted this post because I am loving so many of them). I bought one not shown here, but I'l show you next week when it comes :)
