A computer support assembly that is steering wheel mountable includes a frame that is disposable upon a wheel of a steering wheel. Opposing side edges of the frame are configured to abut opposing sides of the wheel. A pair of hooks is coupled to and extends transversely from an upper edge of the frame. The hooks are configured to reversibly couple to a top of the wheel. A tray is hingedly coupled to a lower edge of the frame. The hooks are positioned on the frame such that the frame is couplable to the wheel. The opposing side edges of the frame abut the opposing sides of the wheel to stabilize the frame. The tray is hingedly coupled to the frame such that the tray is positionable transverse from the frame for use. The tray also is positionable substantially parallel to the frame for storage.
