You know how we have plug points all over the house? And how we never pay too much attention to it unless it stops working and our entertainment ceases? Well, one designer took the design into serious thought and created this brilliant concept of the Plug In Chairs. As goes the name, they are shaped like plugs and can be plugged on top of each other saving space and money. They come in colourful designs and can be plucked out of its stack to sit and put back up when you need the space. Interesting.
