Arrived today!  Happy with ivory color and am impressed with the rubber backing for the non-slip feature.  The entire bottom of the cushion is a sheet of rubber grip material and it works great!  We're using them on a set of matte (low or no gloss finish) wooden chairs.   The thickness of the cushion is fine for me (about 130lbs) and I like the thin look (blends well, doesn't attract attention) but I can see where my husband and most others would want a thicker cushion appropriate for their weight especially when sitting on a wooden chair.
