On my First Day South and West trip I used the 184 Frome - Bath. (Quicker services are available). At one of stops within Frome an elderly lady boarded. She walked very slowly with a limp past the inward facing seats up a steep step in front of the front wheel arch. Past the wheelchair/buggy space and tip up seats. It was approximately six metres, over half the length of the bus to reach the first forward facing seat on the level.
