Hi Azca33,
Dunlop usually has a stronger “rubber” smell that usually lasts longer than the sweeter small of Talalay but both will dissipate to levels below most people’s ability to detect within a matter of days to a few weeks.
There is more about the typical smell of latex in post #2 here and some suggestions to help dissipate the odor of a new mattress in post #3 here.
