I use two of these over plush carpets. After my stroke my dining room is now my (temporary) bedroom. While they do move a surprising amount they are not cracking even with wheelchair activity. My standard chair mats borrowed from my office have cracked when used over padded plush carpet in my living room. Excellent quality.
Bottom Line Yes, I would recommend this to a friend
Bought two less than a year ago for use on thick pile carpet. They both began to wear out within six months and now both have a huge hole in the center. Now I need to replace them. Would not recommend these for use on thick pile carpet.
Bottom Line No, I would not recommend this to a friend
