Rough material, doesn’t stay on because it doesn’t have any elastic to grip and stay. Extremely loose. The only good thing about this product is the fact that the sizing covers the whole top side.

I purchased this for my daughters nap mat for school. The material is not comfortable and wish it had elastic to it would stay on better. Will keep because no one else has sheets for that size mat

I have not had any problems with these for the past 4 years! The children are able to put their own sheets on. I have the blue and turquoise mats.

Would be nice if they were not white and they need elastic to help hold them on the mat.
