Each year, tens of thousands of people in the U.S. go to the emergency room after falling using walkers and canes. The Zeen was designed to be a safer walker, using a gas-spring technology that inventor Garrett Brown developed when creating the Steadicam movie-camera stabilizer in the 1970s. It allows users to smoothly move the chair up and down, so they can more easily shift between walking, standing, and sitting modes. “There was something missing between walkers and wheelchairs,” says Brown, co-founder and CEO of Zeen maker Exokinetics. He believes the Zeen fills that void.
