This rug has no top or bottom.  It’s basically like having a even blanket on the floor.  While we have been fortunate to turn it over for wear, it slips out of place constantly.  We have a rug mat  and have attempted double sided rug tape but there is no backing for the tape to stick to.   It might work in a low traffic area but I don’t recommend it if you have dogs or kids that run or an older person who might trip if there is a fold in the rug.
