This rug was a stiff board I had 25lb weights on it for 3 weeks and it wouldn’t lay flat - that was just the beginning- my son and I both started coughing violently each day worse and worse we saw so many doctors and ER visits - doctors couldn’t find anything wrong after test upon test they had us do an air quality in each room and only that room with the rug had issues so we realized the rug was saturated in some kind of chemical causing our lungs to react my husband pulled it out and threw away and within a week we were no longer coughing and we redid the air quality tests and everything is fine now - do not buy this rug and it was expensive on top of it - macys did not care did not try to remedy it nothing so I paid for this got violently sick and nothing do not buy this
