The workstations in an open-plan office are the area for concentration and interaction. The ergonomics of the workstations are vital: height-adjustable tables and adjustable swivel chairs ensure that everyone is sitting optimally and can also work while standing. Room acoustic planning is essential for everyone to feel comfortable: You should be able to communicate easily and not find the room too noisy or quiet. People move to other areas of the open-plan office for longer meetings, creative work in a team or meetings: to the meeting room, think tank or arena. There are screened retreat areas such as work lounges or booths for highly concentrated individual work or phone calls.
