All new materials have their own particular smell, which gradually disappears. Airing and vacuuming the rug will help to eliminate the smell.
The rug is machine-woven.
Rugs with structure or hard edges can cause marks on soft wooden floors even when used together with an anti-slip underlay.
To get the edge of your rug to lie flat without curling up, fold the edge in the opposite direction and place a heavy object on top for 2 days.
