Just finished up our dining room area with our new laminate wood floor and it looks great. I layed it on a osb sub floor that I leveled to the best of my ability. While walking across the floor it feels nice and firm as it should. However, if I stand back 10-12 feet from the floor and have someone walk across it, I can see it move or flex ever so slightly. I tried to measure this movement and the most I can see it move or flex is a 1/16 of an inch. Is the movement the foam underlayment compressing or slight uneven of the sub floor? Is this something I really need to worry about? The laminate is 12mm thick and has the padding attached to it. Any thoughts or input would be great!
