In Canada we have a company called Princess Auto which regularily
advertises a seat which is manufactured by VW which would be a lot better
than a garden chair. This seat is mounted on a non swivel base and is vinyl
covered with headrest and seatbelt. It would have to be bolted to the floor
or maybe a track. They sell regularily for 149.00 Can but this week it's
on sale for 129.00 Can.

I just looked at the catalog and I see they have a website

www.princessauto.com

Failing that I was at a shop outside Moncton NB last week and I saw a tan
chair on a swivel base in fair condition. I don't know about the logistics
of this for shipping but if you want I'll see if I can get a phone number
of the shop when I'm around there next week.
