Does the seat move around?

Yes - even when it is upright it just wobbles around - then when you sit on it that wobbling is very unnerving. Its not fit for purpose so I am sending mine back. Cheap rubbish - spend a little more and get a better quality seat.

is the loo seat easy to fit especially for someone with RSI

I have limited movement and found it very easy to fit, tip; do not over tighten and read the instructions at least three times as it comes with two fittings, you can only use one. Cleaning afterwards is so easy it unclips

Does this fit a RAK 600 series toilet

Sorry, I just took the measurements and shape.

What is the width of the pan hole? Its length is given as 285mm but the width is not given

Just measured the width of the pan hole and I get 221 cms
