How durable will these tiles be in daily industrial office use (mainly rolling chairs)?

Our 6mm Energy Rubber Tiles were designed to be used in home gyms where heavy equipment and weights would be dropped on them, so these rubber tiles will perform excellently in an office setting. Rolling chairs will not damage these tiles in any way. The only thing that could happen is if a tile were to come unlocked, and the chair was to move it a bit. To fix this, all you would have to do is just re-interlock the tile.
