I declared my aftermarket seats to the insurance,
Made no change to the price of the premium, but they said if I hadn't and tried to make a claim, then you could have issues.
Either way, they would only pay for the OEM seats to be replaced if the aftermarket ones were damaged.
Fine by me, as the OEM are very expensive..... don't you just love the logic of insurance companies.

PS mine will be up for sale early next month....... complete with Recaro subframes.......
+1 Just renewed my insurance for the year and mine said exactly the same but at least it is on record now as is everything else on my cars.
