We had actually made this mat a false order, because we had overlooked that it handelt- a mat for carpets we actually have laminate. By the knobs on the bottom, the mat is not to be used on laminate. Did they want to return, but the return-shipping would be almost as expensive as the value of goods arrived ansich (= bulky goods). Therefore, we decided to keep her yet and she lay under our recliner chairs standing on carpet. So it prevents the nasty marks the chair feet in the carpet. No one can what our Dusseligkeit and the incorrect order, the description was perfect "for carpet" - have simply ignored. The mat is stable, decent and really seems to be impeccable quality. Therefore 5 stars.
