I spent many hours of my childhood sitting in front of the television trying to vanquish the aliens in Space Invaders. And now, all these years later, I want to invite one of those aliens into my home -- as a sofa!This sofa concept is from industrial designer Igor Chak. Made with memory foam, leather and glass, the Space Invader sofa is a whimsical reminder that interior design doesn't always have to be so serious. In fact, it can be downright otherwordly. While this sofa may not work in my humble little abode, it would be an amazing addition to a gameroom or for the geek who has everything.
