I need a large, absorbent door mat to go on an amtico floor but I’m confused about what is suitable. I’ve read that the wrong type of backing can mark the floor but there’s conflicting advice about what is the right type. Everyone seems to agree that turtle mats are ok but they are rubber backed and the amtico website says “non rubber backed” I’ve seen vinyl backed ones that specifically say they aren’t suitable. Anyone got any idea or experience?
