The unit provides the expected mobility for the TV screen but the shelf is a bit too small to provide the functionality desired. There are few if any dvd players/cable boxes/game centers that would fit well on the small shelf. I have placed the a cable box on the shelf but at least a third of the box overhangs the shelf in all directions. From side to side that is tolerable but from front to back that makes for a somewhat precarious setup as there is no room to overhang the back side and it all hangs over the front. It works but be careful when going by it as the item on the shelf can be knocked around easily.
