You probably could, but then you'll have the airbag light on in your dash.
I stitched my drivers seat up myself as no-one could guarantee to do a decent job of it. Cost me a couple of quid for the thread and needle and about 4-5hours of patient graft.
You could but for safety you should change the seat back the metal bit.Could i not get it stitched back up without an airbag?
