After watching Gary Hustwit's Objectified, I was thinking about how to relax the sedentary people. Long periods of inactivity will do harm to people's health. This led me to choose a special chair as the project. First, I made an ordinary chair, and then I processed it on this basis. Then I designed an alarm clock on the back of the chair. The alarm clock has a strong polar countdown on it, which will remind you to take a rest when the time comes. And I replaced the support rod of the chair with an electric spring. As soon as the countdown is over, the spring will spring up to make you have to stand up and rest while ensuring people's safety.
