Defender County 110 Middle Row Seat Replacements?

I'd like to replace my centre seats on my 99 County 110 for something high backed. Anyone done this easily with seats from another vehicle? - my existing ones are black elites up front, black low backs in centre and benches at rear. Appreciate replies from anyone who has actually done this or seen it done and knows which donor vehicle. Thanks

elsewhere advised exmoor trim do high back conversions for the little square middle seats - each seat cost me £150 - and it retains the existing frame but supplies new seat cushion and high back

Only retains the existing frame IF you have the individual rear frames. They do not fit with the 60/40 frames.

Ive gone a bit fancy and attempting to fit Range Rover Sport rear seats

Need to fabricate a new seat box but ill get them in eventually

wow - looks amazing

Well they are just sitting on a a block of oak in that pic

Ill get round to fitting them properly soon i hope

See, even your blocking is posh - no softwood in sight
