The rugs are very good looking, we have them in front of 2 sliding doors.  They do not have any non-slip backing so we had to add that or the rug would slide under your foot coming in.  The other thing is the corners seem to curl up a little.  They have been in place for a little over a week, so we hope that they will flatten out over time.  We have put books on them, turned them upside down, etc.  We will see going forward.
