Looking for MOUNTS that combine reclining sienna seats & swivel mounts in E-series.

Found a pair of reclining seats out a 2020 Sienna. I would like to use those as my driver and passenger seats in my E-350.

Currently using swivel mounts from Ray, 1der, and I want to keep and mount the sienna seats.

I am aware this has been posted somewhere before and would like updated information.

Vendors to have updated what they do and don't sale; Expovan no longer makes them and Ujoint only makes them as rear seat mounts.

AFAIK -- there is no aftermarket support for swivels for the Sienna seats currently.

I'm working on swivels for my van currently -- but they aren't going to be MG/Expovan quality and, frankly, it doesn't seem like a very lucrative market to enter given that both Expo and UJoint have left that world.

Once I'm done -- I'll gladly share my solution and could build you a set if they look good to you.

I reckon it will be difficult to use the 1der mounts with Sienna seats... the mounting of the seat is different enough that the platform on the 1der/sportsmobile swivels isn't exactly height/angle adjustable.

I have 3rd row Sienna seats as well. Not the fancy pants reclining ones tho. I'm working on a swivel too.

A unit bearing from a front wheel works well as a swivel bearing.

Contact Weldtec. They have made some seat brackets for someone else and since hes a fab shop, he can make pretty much anything you want.

You will not enjoy Sienna seats on a fixed base, swivel or not if you are shorter than 6 feet tall.

What do you mean by this? That you'll be up way too tall with the standard height base?

Sitting on the sienna seats once installed feels completely different than a stock seat. If you build yourself a fixed base (meaning no height or tilt adjustment) the odds of you manufacturing a base that puts the seat at the exact sweet spot for your own body is slim and none. So you may finish your install and it seems ok, but then after a week you realize it needs to be tilted forward more or lowered a quarter inch ect..... but you cant make adjustments because you have a fixed base with no adjustment short of perhaps sticking some washers between the seat and the slider to tilt the seat forward or back.

Then if you manage to find that sweet spot just right for your body, if anyone else drives your rig the odds of them fitting the seat the same as you are slim.
Not trying to discourage you, just thought i would mention it.

As far as standard E350 seat risers go, they are way to tall for sienna seats and you have to keep in mind that theres an airbag module and wiring under the drivers seat that you must clear as well. Im sure you have looked at the sienna seat post on expedition portal forum?

I searched for some prefabbed seat bases for my rig for a couple weeks. But then i realized they arent adjustable at all and what feels ok monday on the way to work may not feel ok friday on an extended 3 hour drive to go fishing. That said i opted to use 6 way electric bases under the seats instead of a fixed base.
