They each agreed upon the preference for the "Long Seats" at the back of
the
Routemaster and most interestingly they each remarked upon how difficult
it
was FOR THEM to get to a seat on a new SLF bus because "They`re always
crowded full with Push-Chairs and Prams"

Yes that is indeed something I hear of a lot. Also the rear section of many
low floor buses is near enough inaccessible to many because it is raised up
so high and it can be quite precarious getting down again if you do make it.
Also where there are side facing seats towards the front of buses they are
dangerous because they are not deep enough and there are insufficient
handholds resulting in a tendency to be thrown off the seat when cornering.
Finally in the wheelchair areas there are often seats on a spring up
mechanism. Unfortunately in order to reach the bell push it is necessary
for many people to raise themselves off the chair slightly, only to find
that is has sprung up and is no longer there when they sit back, leaving
them deposited on the floor. So these low floor buses might be more
accessible in terms of boarded and alighting but the same considerations can
greatly reduce the number of usable seats for many and add several new
dangers. Indeed on some of the double decker low floor buses there are only
about four seats that are really suitable for many people.
