Abstract

The present invention relates to a device comprising a mat ( 1, 2 ), which has at least one through clearance ( 1.1 ) so that a remaining part constitutes an outer mat ( 1 ), at least one inner mat ( 2 ) being arranged in said at least one clearance ( 1.1 ) and said outer mat ( 1 ) having at least one first device-attributed, upper layer ( 1.4 ) provided with at least one non-rigid pile ( 1.5 ) of plastic in the form of artificial turf. Said inner mat ( 2 ) has at least one second device-attributed, upper layer ( 2.4 ) consisting of a material having a substantially smooth upperside and that is denser than the material of the first upper layer ( 1.4 ) of the outer mat ( 1 ). The present invention also relates to the use of the device.
