Hello. I would not recommend purchasing this product. And if you love the look and feel that you want it, please remember the return policy. We purchased this item and as per previous bad reviews experienced the waves and lumps that occur when you open the package. Personally tried every possible remedy. It will not lay flat! This might be the occasional issue with the product. But if you get a bad one don’t hesitate to return it! Totally useless as a rug. Wasted a great amount of time on trying to correct the problem. So in closing if it forms moguls initially. RETURN IT IMMEDIATELY. LOL best of luck
