Yesterday was 1 April ( April Fools’ Day ), and this door chain concept designed by Artemy Lebedev fell into the category of a good joke. I don’t like the April Fools’ Day, but this door chair is really funny, and appropriate for a day like this. The only problem with something like this might be …if you have a visitor you might have a dialog like this : “I’ll be right there, hold on!“, after 2 minutes …  “Just one more minute, I’ve almost got it!“, because the chain is long enough to reach the far end of the maze. - Via - Tranism
