Ya! / Office Furniture


Ya! is a space divider that creates a phone-free zone in office, allowing employees to be fully immersed in a brainstorm session without the interruption of argumented technology and bring back the happiness of the conversation itself. By putting the phones into the “teeth”, the phone will be locked in, while an illuminating smile will be shown, to assist people to enjoy communicating and interacting with each other. After the meeting, if people want to continue to stay in this technology-free state of mind, they can take the tooth with them to their station, and work in a clearer thought with more mindfulness.
