Seem to be made from tough good quality material and it has buckles to clip round the headrests but apart from that you have to tuck it in between the back and the seat cushion the elasticated bottom which won’t stay in place as there is no lip to hold it on- the design of the front bottom of the rear seat in my 72 plate A4 is flush and material between the elastic and the good quality seat cover is very thin and stretchy; it does what I need it for very well- that is to put muddy stuff on the back seat but how good it would be if you used it for dog protection or people I am not sure but then is only “semi tailored” as described so overall good if you remember that and it suits your needs
