I had a thing that went ontop of the chest of drawers with a side to stop him from rolling off, but as soon as he started seriously moving I took it off and have changed him on the floor ever since. When he was newborn & slept in the bassinett in our room I put the change mat on the blanket box at the end of our bed for nighttime nappy changes, cause it'd be silly to have to go into his room to change him when we're all sleeping in the one room.
