Surprisingly, the chair, which weighs in at around 4 pounds, was designed in a way that isn’t too conspicuous. A 90-degree twist of a dial located in the seat is all it takes to detach the chair’s back, which connects to the helmet. This means it’s easy to don your protective gear as you feel the first tremors of an earthquake run through the ground. |
