The StayPut bath and shower mats mats are soft, comfortable, free draining, and now manufactured in the unique PER® material combined with an anti-microbial 'Silver' additive which actively inhibits mould and bacterial growth. With added strong grip suckers in a new configuration, they have successfully completed ‘Slip Resistance’ testing by Independent Laboratories to Level 1 of the BS Standard BS8445:2012.Easy to clean – machine washable at 40°C and allow to dry naturally. It even has an integrated hanging loop. The shower mat is not considered suitable for showers with an uneven non slip surface, or where the surface has raised contours, as the suckers may not be able to fully adhere to the surface and that could cause the mat to slip and cause injury.
