A moveable platform for a laptop computer has an angled support base to angle the laptop keyboard and elevate the laptop display monitor. The angled support base forms an airgap between the moveable platform and the desktop to dissipate the heat from the laptop computer. A separate cooling fan system integral with the support base can also dissipate the laptop computer heat. Spherical roller assemblies on the bottom of the platform move the laptop computer around the desktop. The spherical roller assemblies have a Teflon® spherical ball surrounded by a plurality of Delrin® spherical ball bearings in a Nylon® semi-spherical cavity. These non-metallic materials provide smooth quiet operation with minimal frictional resistance and are non-abrasive to the desktop surface. A braking mechanism at the front of the moveable platform lifts the front spherical roller assemblies from contact with the desktop to lock the moveable platform and laptop computer into position on the desktop.
