I would love to rate this 55 for its quality, softness and quick settling ability. However, when it came in the mail and we laid it out yesterday, we discovered 24 corners have this very dark discoloration. I would love to discuss this with someone from the company to see if there is a way I could clean it out or get a replacement as this is obviously an isolated incident and not how all of their rugs look but it was a lot of money to get a damaged product. I do love the rug, we placed it in our daughter’s nursery to hide retro carpet. Highly recommend besides the discoloration!
