Silent Chair / chair

Silent Chair
Silent Chair

Library:what breaks my silence?
Every time you move your chair, you have to make a noise because of the sliding friction between the chair and the floor.
A universal wheel with a spring is embedded in the bottom of each chair foot of Silent Chair.When no one is sitting on Silent Chair, the chair is in a sliding state. The sliding friction is changed into rolling friction to reduce the noise caused by moving the chair.When someone is sitting on Silent Chair, the springs are compressed, the universal wheels are pressed down to the foots of the chair, and Silent Chair becomes stable.
