Re: ISO passenger swivel seat base
This is another "new purchase" lead, so not sure if it's one you want (it's not DVT though). Anyway, Sportsmobile sells a passenger seat swivel in their online store. It looks as though it may be the same design as the one in my late 90's SMB, and if so I can say it works fine, is a good height, etc. I have no complaints about it.
There is a little "shuffling" that makes it easier to swivel the seat around (move seat forward/aft/open door to clear armrest/etc.), but I think that's more a function of the size of the seat and the given space, not the specific swivel mechanism.
