I like the concept of lowering and raising the desk, to changing from sitting and standing, but it might not be ideal for a call center environment – it will be too loud and unable to hear while talking with customers. An option of a rectangular version might be great as well. The ideas are endless, and it could start from here. :)
Ergon Desk is a six-person desk consisting of six workstations arranged in a circle, making it easy to collaborate with everyone on the desk.
