Seeing this special chair, does it remind you of the massage slippers with rubber soles that we wore when we were children? This chair is called the "Painful Chair". It is covered with dense hard bubbles. I don't know if it will massage the buttocks when I sit down. Although it is called the pain chair, it is not painful at all and is very comfortable to sit on. The designer calculated the structure and size of the three-dimensional space, drilled uniform small round holes in the wooden board with a hand drill, and then inserted small wooden sticks shaped like lollipops into the round holes. The entire chair has a total of 800 "lollipops" and is made entirely by hand. The reason why it is called a pain chair does not mean that you feel pain when you sit on it, but because of the process of the designer making it.
