Seat Cover That Did Not Disappoint!
Color: Pearl, Size: Front Seat Cushion-1 Pc
So Soft. Good under-side grips. Didn't have time to 'properly' attach, so I just put the cover on top of the seat. That was about a week ago and it hasn't moved. Wonderfully cool and there's no more sticking to the seat in the heat. Worth the price.

Good seat COVER, but not a seat cushion
Color: Grey, Size: Front Seat Cushion-1 Pc
First, it would be very helpful if the description/information did not use the word "cushion" as this implies some sort of padding in addition to the cover. The cover has a layered backing but there is no cushioning or padding like material. That said, it is a very nice sheepskin cover. It was well packed and the sheepskin material itself is soft. It is a good size and nice to sit on. However, I will return as I need some actual padding to make my very firm car seat more comfortable. My rating would have been 5 stars otherwise.

Nice comfort and warm seat cover
Color: Pearl, Size: Front Seat Cushion-1 Pc
Used when traveled to Florida and back (3,000+ miles). Nice comfort and fit onto my Honda CRV seat good. It has straps and clips to hold it in place and rubber backing to keep it from moving around. In the winter it warms you up quickly, added bonus not expected. The quality is good, not problems with piling, or coming apart.
