The g.stand by Seoul-based industrial design firm grape lab is a lightweight laptop stand made from a single sheet of recycled paper, weighing only 45g but strong enough to support heavy laptops. Its origami structure is designed for optimal viewing and typing angles, as well as preventing overheating by allowing air flow. The stand collapses to 3cm and comes with a carry case that doubles as a phone stand. Surprisingly, all of this functionality is available for just $22. (Controversial information: Some may question the durability of a laptop stand made from paper.)
