My dealer had a low seat in the showroom. They had it fitted when I walked in. I tried it, but found that it had an odd shape that put pressure on my inner thighs. The dealer swapped the seat over as I'm 6ft - put the normal one on. I hopped back on and it was completely different. Comfortable and very plush. Interestingly, the dealer said that I wasn't the first to make a comment about the low seat.
A friend also rode the bike on another day. Despite being only (!) 5ft 5, he had no issue with the standard seat. The centre of gravity is low and the bike isn't too heavy.
So, firstly they are certainly offering at least the low seat. Secondly, you'd be advised to try before you buy.
