Lounge Seat

I was the one looking for the height of the seat base. My seats are missing and the popular 10 inch base sounds too small. Good to know that before I spent $200 on something that I would have to modify. So is 16 inches the base height on the rest of ya'lls. I saw that florida seat as well and it looks like they'll go up to a 14 inch base height with out additional cost if I remember correctly.

Thanks,
Buenos
