It's the supermodel of chairs, the super-skinny Slimmy Chair. The origami-inspired chair weighs just 20 lbs. and when folded flat is less than an inch thick. As lightweight as it is, the PVC and aluminum construction has an outdoor durability of 25 years. And like a puzzle, the Slimmy is made of a single sheet of material.
The Slimmy is available in straightback or inclined positions and both are available for $360 at born design.
