I agree. If one chooses a floating floor and than hard mounts heavy items on it, it SHOULD NOT work well.
Guess, like most things, if you want them to work, follow the directions.
For our floating floor, that means an extra sheet of 1/2" plywood to mount heavy objects and quarter round affixed to the wall to cover the expansion gap. And, yes, Dianne did a REALLY nice job of matching quarter round stain to the new cork flooring.
Now, all I have to do is finish installing the floor and put down the quarter round.
