No retailer or brand sees our picks before they are published or has any say in them. How we choose.
Buy a base made for your van and side. For a 2014 to 2021 Transit, the Vahaha FTP003 and FTP004 pair turns both front seats and lists a 2-year warranty (per the Amazon listing); the FTP004 alone does the passenger side. Econoline owners have the Lamerto base.
A swivel base sits between the seat and the floor, so it is part of the seating system. FMVSS 207 requires each occupant seat other than side-facing seats to withstand 20 times its own mass forward and rearward and to stay in its adjusted position. Vehicle-specific bases installed per the instructions are the conservative choice; universal plates need engineering.

How we chose
We preferred vehicle-specific bases, then compared fit, side, rotation and warranty.
Seat standards
FMVSS 207 sets out how seats and their attachments must hold under load: 20 times the seat's mass forward and rearward for most seats, and the seat must stay in its adjusted position. A base made for your van uses its factory mounting points; a universal plate depends on how it is fitted.
Height and payload
A swivel base adds a layer under the seat and weight that counts toward payload (49 CFR 571.110). Check with the payload calculator and see the van build guide for where seats fit in the build order.
Frequently asked questions
Are swivel seats in a van legal?
Seats and their attachments are covered by FMVSS 207. Use a base made for your van, install it per the instructions and check your state's rules.
What swivel base fits a Ford Transit?
For 2014 to 2021 Transits, FTP003 (driver) and FTP004 (passenger) bases, sold singly or as a pair.
Can I swivel the driver's seat?
On many vans, yes, with a driver-side base such as the FTP003 for the Transit; check clearance to the door and parking brake.
Do swivel bases raise the seat?
The base sits between the seat and the floor, so check headroom and seat belt fit after installing.
Is a universal swivel plate a good idea?
Only with engineering help, which HWHongRV's own listing recommends. A vehicle-specific base uses factory mounting points.
