Face it: in Japan, the ratio of available seating to time spent waiting just sucks. Smartphone games and apps help kill the time, but what will rescue your poor aching feet? That’s where the ingenious Book Stool from Going Furniture sweeps in to save your soles. This 5cm-thick portable “book” fans out in a flash to become a stool that can support up to 80kg of weary bones. Available online at Amazon (¥3,240), it can be stored in your bookcase when at home. At 1.62kg, it’s a little hefty (think coffee table book), but it’s a fair trade if you consider that it will support you (and your reading material) in return.
