These are a perfect fit for my Mazda CX5 seats. I got the grey which compliments my interior and hopefully will not get as hot as black ones would. The shearling covers are plush without looking too hairy. They are real wool despite some reviewers opinions. (they feel like one of my sheep, only cleaner lol). The attachments work well. Just slip the plastic piece through the seat crack until it flips and holds. Mine also came with elastic straps and hooks to anchor the front but I can’t find a good place to hook them so I will not use them. The grippy backing keeps them in place just fine. These covers elevate the car interior and are super comfy. Very happy with my purchase.

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.
