I put these in a 2006 Toyota Corolla CE. They are somewhat thinner than the seat covers sold locally which cost about the same price, when factoring in shipping, for just 2 seat covers (front only). I wanted a full set because of my dog. These are a thin knit fabric backed with a thin layer of foam.The front set fits just about perfectly. The headrest covers are slightly too big but I cinched them up and I think they look fine. On the side of the front seats where the levers are to tilt the seat back, the covers clear the levers but certainly don't look custom-made there. I have 2 levers on the drivers side and I had to manipulate the cover a little to clear both of them and it is obvious that it is a slip cover from that vantage point.The back side of the front seat seat back covers is just thin knit, no foam, and in my car it leaves 3" or 4" of the lower back of the seatback unprotected and not looking so snazzy (my seatback is beige and the cover is black so it's very obvious).The directions said that one part of the back seat cover was bigger and that would be the backrest section. I couldn't for the life of me tell any difference. I finally made the decision based on a slight difference in construction and apparently I guessed right. The seat portion has a thin "skirt" that goes all around the vertical edge of the bottom seat cushion.The backseat bottom cover fits very nicely and the zippers happen to fall right where my seat belt buckles come up, so I just unzipped the cover slightly to accommodate the buckles. Works for me. Usually only the dog is in our back seat; if you had people in and out all the time, maybe the zippers would come further undone although they seem pretty secure. I also wonder if it would be uncomfortable to be sitting on a zipper. I think it would only affect the person in the middle which is a pretty uncomfortable position anyway. I laid a crib blanket over the backseat seat for ease of laundering and a little more protection from dog claws.The backseat seatback cover cannot be well secured in my car but I am using it anyway for dog protection. The consumer has to cut holes where they need them, for the headrests. I haven't done that yet but when I do, the headrests will hold up the cover. It definitely does not look good (see my photos) but it will serve my intended purpose of keeping my original upholstery in good condition.Probably the backseat covers can be secured better if you remove the seat from the car and/or undo the upholstery panels on the back of the backseat seatback but I'm not going there.All these "seatbacks" and "backseats" and "front seatbacks"!! I hope you can figure out what I'm talking about. I'll try to get some photos posted.
