Nick never really asked how seats appeared at random; he figures it was someone who went multiversal dumpster diving and brought seats each time a new comer arrived in the Nexus. "Magic?" It sounds like a good way to explain things that can't be explained, at least it seems to work that way when trying figure out an explanation for how things work in the Nexus.

And then finally it hits Nick, and he ahs. "It is a bit of a figure of speech. But there are plenty of chairs and couches to sit on. As for your answer about colors. Yeah, I know colors."

He holds his hand up. "Red, blue, purple, green, yellow..." He lowers each finger as he spouts off a color. "But nope, we don't have anything digital back where I come from."
