There are a wide variety of top styles, including rectangular, square, corner and L shaped as well as other geometric profiles.

Apart from the commonly used single worktop, it’s also possible to get these desks with split-level surfaces. The more popular ones have a section at the front where your keyboard and mouse usually sit. This front section is adjusted by hand and connected to the rear top with the kind of mechanism used on adjustable keyboard trays.
