I had one of them Bob Church RutlandBoat seat and it was the biggest waste of money, they look good and thats about it!
I sold it and got an inflatable boat cushion from Chew Valley for £38 and its the business, comfy no hassle dose not get in the way, light weight andyou can quickly turn round andcast to rising fish behind you unlike the Bob Church back breakerand it doubles as a life boy if you decide to throw your boat partner in!
