Now that's a evil lair chair if I've ever seen one.
Giant Amethyst Crystal Office Chair

This is the office chair created by Japanese natural stone workshop Factory-M after founder Koichi Hasegawa discovered a massive seat-shaped chunk of amethyst for sale during a trip to the United States. It, uh, it definitely makes a statement. One not about comfort. The chair weighs around 218-pounds and features a solid, uncut piece of amethyst. Hasegawa recommends grinding the sharp crystal ends down before actually sitting in it, but why would you ever do that? You ever had a giant crystal in your butt before? I’ve never had my chakras aligned so quickly.
