Detour desks by Metro are available in a variety of different shapes, and top surfaces. The edge is a resilient plastic to rebound from bumps when moving them around. The steel legs are height adjustable, a key feature when you are trying to match the height for a good vertical desk solution.
There are also some great accessories available for these desks. You can get a pivoting pencil drawer which allows you to have little bit of storage right on hand. They also have a flexible umbilical wire manager.
