Hi Ken. I was quoted £2400 for a pair from Morgan, and that was four years ago. So I had a pair of tilting/reclining seats made for me by Shaun at Allon Whites, cost was about £1200, now listed at £1500 but in my opinion very good value. I had heated inserts fitted at the same time - superb in the cold weather. The Allon White seats have continuous adjustment of the tilt using a wheel, whereas the Morgan seats have a ratchet with fixed positions. He can also make the seats thicker/thinner/narrower/wider and give you more lumbar support, etc, however you choose.

No connection, just a happy customer.
