These rugs are on a foam backing￼ so they are fairly thick. I had read a few comments saying these rugs feel sharp when you walk on them.￼ I can see why a few people have said that. However, I wouldn’t describe it as sharp. I think it’s just the way the rug is made. I have not washed them yet, so hopefully they do well in the washer. Overall so far, they look great. I also love that they are not sold in a set and I could choose the sizes that work best for our bathroom layout.
