You can place your laptop in almost any position possible as the mount deck rotates 360 degrees from the stand and head mount, tilts 180 degrees from the stand and head mount, and 180 degrees from the midpoint joint.
To install the mount you need to loosen one passenger seat bolt and insert the base under it. For most cars it should be a seamless process. Alternatively you can buy a universal bracket that can be drilled to the car’s floor.
Instead of clamps or brackets, the laptop uses Velcro straps to secure the computer to the tray. These straps can potentially interfere with typing or block some laptop ports.
