I installed the front seat covers. They are two-piece and can connect together at the joint of the seat, though not needed. Each piece is to be pushed between the top and seat section and stay just fine. Seems to be made well and the material looks like it will last a good long time. The top of the top piece is velcro so the headrest can easily slip in. I havent applied the back seat yet. No mention or indication of airbag stitching.
I would say they are 3.75 stars out of 5. Hope this helps.
