Ever got into an awkward situation deciding whose arm it should be on that armrest while on an airplane? While they're cramped enough already, this situation is all too common. One Hong Kong based design outfit has a solution for it.

Called the Paperclip Armrest, it is a two tiered bar that is meant to solve the battle for elbow space. According to Design Taxi:
The basic concept of the Paperclip Armrest can be executed in various shapes, forms and materials—according to its creators, the only criteria that need to be met for it to remain functional is that "the two levels must be approximately three inches (7.5 cm) apart, with a roughly 8-inch (20cm) gap between backrest and the upper level".
Sounds too good? Will airplanes implement these on their seats? [Design Taxi]
