Heated Seat Question

I am refurbishing some defender seats to replace the Disco 2 seats currently fitted in my 110 CSW and have bought some heated seat pads from Ebay. I have got the Exmoor Trim foams and covers and have the instructions for those from their website and YouTube but am not sure if I use any glue to fix the heated seat pads in place on both the squab and the back. As I have not started rebuilding them yet it may turn out there is enough pressure between the cover and the foam to keep them in place but I wondered what others have done?

I used the Exmoor Trim heated seat kit when I rebuilt mine and they've got an adhesive backing on them , so I think they may need fixing in place but I'd ask advise on which glue is best you probably need something like this

but I'd ask the supplier if its suitable .

Cheers Ian I was supplied some glue by Exmoor Trim for fixing the covers to the foam so that might be suitable. Not sure if my ebay specials have any adhesive backing!
