I think the IEP seats are not nearly as nice as the leather HST seats on GWR, but this partly due to new trains fire regulation, to do with fire retardation etc, last week I spent about 9 hours on Wednesday trying out the IEP’s in First class, did Padd-Bristol-Padd-Swansea-Padd, The seats are fairly comfortable and reasonably wide, with charging points at every seat, they look nice enough but nothing special, they recline nicely, I found them comfortable enough for the 9 hours I was on them for, certainly didn’t get off thinking never again, Definitely its a case of paying for more space and room, probably slightly nicer seats than standard, though didn’t try the standard seats,
I think its just a general lowering of the difference between First and standard class, new trains First class definitely doesn’t have any swish factor about it, which a shame, something like VTEC First Class with leather seats and a swish interior would look so much better on an IEP than what they have now, but it does the job, and most passengers who use it will be fine with them, which is who GWR are bothered about at the end of the day.
