I wanted to wait a few weeks before writing this review. We bought two of these in two different sizes for our family room. They arrived promptly, of course, Wayfair is very good about prompt delivery.  The rugs laid out flat quickly. I do not have any slip protection under them; hasn't been needed. They handle being vacuumed well. The only downer is not the fault of the rug, but we have a dog with light colored hair and it shows on the darker parts of this rug when he sheds. I still vacuum every other day as I normally would . . . Only takes about 5 to 10 minutes to do both so not a big deal,
