I travelled on 258 earlier this week and yes the seats are hard but no different to most new stock these days. My understanding is that the specification for most new stock is developed by the Government so its like buying a car you can have the basic model or a deluxe model with varieties inbetween. It apparently does not cost too much for better seats but taken over a large fleet it obviously adds up. Talking to a driver on the Goblin line he was praising the new units saying they were a pleasure to operate. However I did notice a number of door seals flapping in the breeze!
