The Recaro's technically fall under trim so they wouldn't be covered under even the most comprehensive extended warranty. To be honest trim under the manufacturers 3yr warranty is a grey area 9/10 they will declare it wear and tear. In my experience R27 seat bases always go the RUK customer services route.
Having said that, if you get in and out of the car properly then you won't have any issues.
dont take it they do there best to get out of everything as it is ffs!
Is that a NO don't get it???
