A strong swivel seat base gives a Transit van owner a rotating seat matched to the correct side and vehicle fit, with mounting hardware or a clearly stated locking setup. The Vahaha FTP004 is a clear passenger-side choice, while this roundup also includes dedicated SCOPEMA driver and passenger bases, paired left-and-right bases, and broader-fit alternatives. Fitment claims are not equally precise: some products name Transit 150, 250, and 350, while others mention Transit alongside Sprinter, T5, or T6.
Check your van, seat side, and mounting pattern before choosing; a 360-degree claim alone does not establish compatibility. The comparison below prioritizes Transit-specific fit, then useful details such as hardware, locking positions, and whether the listing covers one seat or both.
The Vahaha FTP004 is the strongest starting point for a Transit owner seeking a passenger-side swivel. It explicitly fits Transit 150, 250, and 350, identifies the FTP004 part number, and includes necessary mounting hardware. Its listing also describes a 360-degree turntable.
Buyers looking for a driver-side base, a pair, or a different Transit fit should compare the SCOPEMA and Weonefit options instead, and verify their exact seat side and mounting holes before ordering.

Detailed Reviews: Best Swivel Seats For Transit Van
Why it ranks #1: Names Transit 150, 250, and 350 passenger fit, specifies FTP004, describes 360-degree rotation, and includes necessary mounting hardware.
A stated 360-degree turntable for 2014–2021 Ford Transit 150, 250, and 350 passenger seats is the defining feature here. It lets a compatible front passenger seat turn toward the cabin, changing how the seat faces when the van is parked without broadening the listed vehicle fitment.
The FTP004 model number and explicit Transit 150, 250, and 350 fitment across 2014–2021 give buyers concrete checks before planning an installation. The package includes a passenger-side swivel base and necessary mounting hardware, so those components are supplied together for the conversion. Vahaha also describes installation as easy, but the listing does not provide installation steps or measurements. Treat this as a right-passenger-side option, not a driver-side base or a universal van swivel.
- 360-degree seat rotation
- Listed for 2014–2021 Ford Transit 150, 250, and 350
- Passenger-side base
- Necessary mounting hardware included
- Fitment is limited to the listed Ford Transit models and years.
Skip it if you need a driver-side base or a swivel for a different vehicle; this listing specifies the right passenger side for 2014–2021 Transits.
For a Ford Transit 150, 250, or 350 owner converting the 2014–2021 passenger seat to turn toward the cabin, this package includes mounting hardware; check the model year and passenger-side position before choosing.

View on AmazonWhy it ranks #2: Identifies a passenger-side swivel compatible with Transit models, with a stated fit beginning at the 2013 generation.
SCOPEMA identifies this as a passenger-seat swivel for 2013-and-newer Ford Transits, a clear fitment boundary that helps narrow the choice to a front passenger conversion. The listing is concise, so buyers get a named vehicle and seat position rather than a long feature set or installation description.
The 2013+ Ford Transit compatibility and passenger-side designation are the useful buying facts: together they help distinguish this part from a driver-side swivel or an option for another van. SCOPEMA lists model number 139790, which gives buyers a specific product identifier to use when checking the application. No rotation range, included hardware, material, or installation procedure is stated in the supplied information, so those details cannot be assumed from the word “swivel.”
- Passenger-side swivel

- SCOPEMA model number 139790
- Clearly identified as a Transit application
- The supplied listing gives no rotation range or included-hardware details.
Skip it if you want listed hardware or a stated rotation range; Vahaha FTP004 specifies mounting hardware and 360-degree rotation for 2014–2021 Transit models.
This is a focused option for a Ford Transit owner seeking a passenger-seat swivel with 2013+ listed compatibility. Choose it when that fitment matches, and seek more product details if hardware or rotation specifics matter.

View on AmazonWhy it ranks #3: A dedicated driver-side SCOPEMA swivel for Transit, making it a clearer side-specific choice than broadly described alternatives.
This SCOPEMA swivel is explicitly identified as a driver-side part for 2013-and-newer Ford Transit vans, making seat position its key distinction. That clarity helps a Transit owner separating a driver-seat conversion from passenger-side alternatives, although the supplied details do not describe its operating range or installation contents.
The driver-side designation and 2013+ Transit compatibility together define the application, while manufacturer part number 139789 provides a specific identifier for fitment checks. The listing identifies the vehicle type as a van and gives a black finish. It does not state rotation degrees, materials, included hardware, or installation instructions, so buyers should not infer those features from the swivel label. Its clearest use is matching a driver-side conversion to the named Transit generation.
- Driver-side swivel

Choose this for a Ford Transit owner specifically converting the driver seat, with 2013+ compatibility stated. The listing is sparse on hardware and rotation details, so those considerations may affect the fit decision.

#4 · Hardware Included
4. Enocos FTP004 Passenger Base
Best for: Transit owners checking mounting holes.
Why it ranks #4: Specifies Transit 150, 250, and 350 passenger fit, identifies FTP004, and includes necessary mounting hardware.
Alongside its FTP004 designation, this Enocos base lists hole-color guidance for several other vehicle ranges, while specifying a passenger-seat fit for 2014–2021 Ford Transit 150, 250, and 350. The combination makes the exact vehicle and mounting-hole selection central to the conversion.
The stated Transit fitment and FTP004 replacement number help identify the intended passenger-side application. Enocos includes necessary mounting hardware and says different holes connect to adapt to different vehicles; its description gives red, yellow, and purple hole groups for specified Sprinter and Metris ranges. That guidance could matter when distinguishing mounting patterns, but it does not change the product’s explicit Transit application. Check the model, year, and hole arrangement before installation rather than relying on the broader vehicle references alone.
- Passenger-side FTP004 replacement base
- Listed for 2014–2021 Ford Transit 150, 250, and 350
- Necessary mounting hardware included
- Hole-color guidance is provided for several other vehicle ranges
- The listing does not state a rotation range or locking positions.
Skip it if you require documented locking positions; SportsMarineRV SM-JZYSID06 lists locking points every 90 degrees.
This suits a Transit owner seeking an FTP004 passenger-side replacement with mounting hardware and hole guidance. The supplied information does not specify rotation range or lock positions, so those operating details remain a boundary.

View on AmazonWhy it ranks #5: Includes two bases for Transit passenger and driver seats and states 360-degree rotation; its hole-matching instructions merit careful checking.
A left-and-right pair is the defining advantage of this Weonefit set, supplying two swivel bases for a Ford Transit front-seat conversion. The listing identifies FTP004, FTD003, and FTP003 references and 2014–2021 Transit 150, 250, and 350 fitment, while emphasizing careful hole matching.
The two included bases cover driver and passenger sides, which suits a project converting both front seats rather than sourcing one side at a time. Weonefit states 360-degree rotation, and its high-strength carbon steel and hot-rolled steel construction is described as durable and rust resistant. The listing gives color-coded hole guidance for selected Sprinter ranges and warns that incorrect installation can cause mismatches; it recommends professional installation. Check the vehicle and mounting pattern before fitting the pair.
- Two bases included for left and right seats
- 360-degree rotation
- Listed for 2014–2021 Ford Transit 150, 250, and 350

- Professional installation is highly recommended, and incorrect hole selection can cause mismatches.
Skip it if you need only a passenger-side base; CCNLHZM FTP004 lists a single right-side Transit swivel with a locking mechanism.
For a Transit owner converting both front seats, this pair offers left- and right-side bases with stated 360-degree rotation. Its hole-matching warning and professional-installation recommendation matter when planning the work.

View on AmazonWhy it ranks #6: States a right-side fit for Transit 150, 250, and 350 and 360-degree rotation, with a locking mechanism described in its listing.
A stated 360-degree turn and locking mechanism make this FTP004 passenger-side base notable for both seat orientation and securing the seat after rotation. Its listed fit is Ford Transit 150, 250, and 350 models from 2014–2021, giving conversion planners a defined vehicle range to check.
CCNLHZM identifies the base as a right-side FTP004 for 2014–2021 Transit 150, 250, and 350 models, so the stated fitment and OE number offer two checks before installation planning. The full rotation can reorient the passenger seat, while the locking design is described as securing it after the turn to reduce unintended movement during driving. The listing also references FTP003 driver-side compatibility in its description, but this product is specifically identified as the right passenger-side base.
- 360-degree rotation
- Locking mechanism secures the seat after rotation
- Listed for 2014–2021 Ford Transit 150, 250, and 350
- FTP004 OE number specified
- This listing identifies the base as right passenger side, not a complete left-and-right pair.
Skip it if you need both front seats converted together; Weonefit’s FTP004/FTP003 listing supplies a pair of left- and right-side bases.
For a Transit owner prioritizing a passenger-side swivel with a stated locking mechanism, this listing covers 2014–2021 150, 250, and 350 models. Its single right-side designation is the boundary for a two-seat project.

Listed on Amazon as: FTP004 Swivel Seat Base Right Passenger Side
View on AmazonWhy it ranks #7: Lists Transit fit through green mounting holes, but its fitment text also identifies Sprinter and describes the compatible seat as driver side.
Color-coded mounting-hole groups distinguish this steel swivel base, with separate patterns listed for several Sprinter, Transit, and ProMaster year ranges. That arrangement gives buyers a visible fitment guide for selecting among applications, but the product title’s right-side designation and the feature text’s driver-side wording need attention.
The listing names four green holes for 2014–2023 Transit applications, alongside separate color-coded patterns for Sprinter, Metris, and ProMaster ranges. That makes the hole layout central to matching the base to a vehicle; use the stated pattern rather than assuming every application shares one mounting arrangement. Its steel construction and black powder-coated finish are described as resisting rust and scratches, which supports durable use in a vehicle interior. The listing is internally inconsistent about side, so resolve that before ordering.
- Steel construction
- Black powder-coated finish described as rust- and scratch-resistant
- Color-coded hole groups for several vehicle applications
- Transit pattern listed for 2014–2023
- The listing conflicts on seat side: the title says right, while fitment text says driver side.
Skip it if you need an unambiguous passenger-side listing; Vahaha FTP004 explicitly identifies the right passenger side for 2014–2021 Transit models.
A buyer comparing mounting patterns across van platforms may value the color-coded application details and steel finish. The side-description conflict is a meaningful boundary, so settle the intended seat position before selecting this base.

View on AmazonWhy it ranks #8: Mentions Ford Transit compatibility and offers 360-degree rotation with four locking positions, but does not specify Transit model fit.
Locking points every 90 degrees give this right-side swivel four defined seat positions across its stated 360-degree rotation. That arrangement lets a parked van or camper conversion orient the seat toward the front, rear, or side while providing specified lock points rather than an unspecified stopping position.
The smooth-rotation mechanism and locking lever work together to change seat orientation and secure it at the listed quarter-turn positions. The product description names campervans, RVs, commercial vehicles, and truck conversions, with Ford Transit, T5, and T6 among the stated compatible models. High-strength steel is cited for stable support and durability. Because the specifications do not provide model years or detailed vehicle-specific fitment, confirm the right-side application for the exact van before planning installation.
- 360-degree rotation
- Locking points every 90 degrees
- Locking lever
- High-strength steel construction
- The listing gives no model-year fitment details for Transit, T5, or T6.
Skip it if you need year-specific Transit fitment; Vahaha FTP004 lists Transit 150, 250, and 350 models from 2014–2021.
This is a candidate for campervan owners who want a right-side seat to rotate and lock at four orientations. Its broad vehicle references lack model years, so exact van fitment remains important.

Four steering slots accompany this base’s stated 0-to-360-degree rotation, giving the passenger seat a full turn while offering multiple plate positions. Its listed title names Sprinter, Transit, T5, and T6 applications, making vehicle-specific verification especially important before treating it as a fit for a particular van.
The metal base is described as converting a fixed original seat into a rotating seat, so it addresses a parked-van seating change rather than a replacement seat. Its black powder-coated surface is specified as rust resistant, a relevant surface treatment for a vehicle interior. The listing recommends passenger-side installation for convenience and accessibility. Although the title names Sprinter, Transit, T5, and T6, it does not specify model years, so verify that the exact vehicle and seat position are covered.

Listed on Amazon as: Passenger Side Swivel Seat Base for Sprinter Transit T5 T6
View on AmazonWhy it ranks #10: Describes a broad RV and mobile-vehicle application rather than a Transit-specific fit, so its compatibility is least certain for this search.
A 360-degree rotating seat base is the central feature of this RV conversion bracket, supporting a change in seat direction within a mobile vehicle. Its supplied facts mention van-life rest and dining layouts, though they also refer to a left-side base while the title calls it a right-seat kit.
The product title identifies a right-seat conversion kit, while the verified description refers to a dedicated left-side swivel base for factory RV driver seats. That discrepancy directly affects which cabin seat the bracket would serve, so it should be resolved before treating it as a driver- or passenger-side match. The description connects rotating a chair toward the living area with resting and dining in a camper van. No vehicle-year fitment, materials, or included hardware are specified in the supplied facts.
- 360-degree rotating seat base
- RV conversion application
- Description connects seat rotation with living-area use

This may interest an RV owner planning to turn a cabin seat toward a living area for rest or dining. The conflicting left/right descriptions are a substantial fitment boundary to resolve first.

View on AmazonWhy matching the mounting holes matters
A swivel can rotate fully and still be the wrong fit if its mounting holes do not line up with the van’s seat and floor. Several listings span more than one vehicle family by using different hole groups: Weonefit describes distinct red, yellow, and other hole patterns, while Enocos likewise instructs buyers to connect different holes for different vehicles. ALMULOO lists a green hole group for Transit, alongside other colors for Sprinter and Promaster applications.
Treat those details as fitment clues, not proof that every configuration fits your specific seat. Compare the product’s instructions and diagrams with your existing mount and confirm the exact side before ordering.
A mismatch can prevent installation or leave the base improperly secured; a claim of 360-degree rotation does not resolve that fit question. If the listing is unclear, confirm compatibility with the seller or a qualified installer before modifying the seat mounting.
How to Choose a Transit Swivel Seat Base
Transit fit and mounting pattern
Look for a listing that names your Transit family and gives a mounting-pattern detail you can verify. Vahaha, Enocos, CCNLHZM, and Weonefit specify Transit 150, 250, and 350 fit, while SCOPEMA describes compatibility with Transit from the 2013 generation onward. Other listings are broader: SportsMarineRV mentions Transit without model details, and ASDJAKZP only lists a generic car vehicle type.
Enocos and Weonefit also describe different hole groups for different vehicles, so check the actual mounting pattern rather than relying on a shared vehicle-family name. A buyer with a clearly matching Transit and seat mount may prefer the more specific listings; someone with an unusual configuration should confirm fit before buying.
Seat side and number of bases
Choose a base that explicitly matches the seat side you want to turn, and decide whether you need one base or a pair. Vahaha, Enocos, and CCNLHZM identify passenger-side bases; the SCOPEMA listings separately identify passenger and driver sides. Weonefit includes two bases and states fit for both Transit passenger and driver seats, while most products here are presented as a single base.
ALMULOO is a caution: its title says right seat, but its fitment text refers to a driver side. For a single-seat conversion, a clearly side-labeled product is simpler to evaluate.
Buyers converting both front seats may value Weonefit’s pair, but should verify that each base’s holes and orientation match their specific seats.
Rotation and locking details
Compare what the listing says about rotation and how the seat is held in position, rather than assuming every swivel works the same way. Vahaha, CCNLHZM, and Weonefit describe 360-degree rotation; ASDJAKZP also states a 0-to-360-degree range. SportsMarineRV adds four locking positions spaced every 90 degrees and a locking lever, while CCNLHZM describes a locking mechanism.
Several other listings do not provide comparable lock-position details in the supplied product information. Buyers who want defined forward, rear, and side orientations may find SportsMarineRV’s stated positions useful, provided its fit is confirmed.
Those who prioritize a specifically identified Transit fit should weigh that fit evidence ahead of rotation claims, since a full turn does not establish safe installation or driving suitability.
Which Transit swivel seat base should I choose?
For a clearly identified passenger-side Transit conversion, start with Vahaha FTP004 Passenger Base: it names Transit 150, 250, and 350, specifies FTP004, and includes mounting hardware. If you need a driver-side base, choose SCOPEMA Driver Swivel for its explicit side designation and Transit compatibility. For both front seats, consider Weonefit FTP004 FTP003 Pair, but verify its hole pattern and each base’s orientation before installation.
Enocos FTP004 Passenger Base is another exact-family passenger option with hardware included. Choose SportsMarineRV Right Swivel only if its fit checks out and four 90-degree locking positions matter to your setup.
In every case, confirm the vehicle configuration, seat side, and mounting holes; the product listings do not establish wiring, airbag, seat-height, or moving-vehicle operation details.

Frequently Asked Questions
How can I confirm a swivel base fits my Transit seat and mounting holes?
Confirm the van’s model, year, seat side, and existing mounting-hole pattern against the product listing before ordering. Check the listed part number when provided, and contact the seller or installer if the hole pattern is unclear. A general Transit compatibility claim alone does not confirm fit for every configuration.
Can a swivel base be rotated while the van is moving?
Do not rotate a seat while the van is moving. The supplied product information does not establish that any listed base is intended for rotation in motion. Use the swivel only when the vehicle is safely stopped, and follow the vehicle and product instructions for operation.
Will installing a swivel base affect seat wiring, airbags, or seat height?
The product listings do not establish whether installation affects wiring, airbags, or seat height. Check the installation instructions and your vehicle’s seat configuration before buying, and consult a qualified installer if these details are uncertain. Do not assume that a compatible mounting base preserves every seat function or clearance.
How do I choose between a passenger-side and driver-side base?
Match the base to the seat side you intend to swivel. The Vahaha FTP004 is identified as a passenger-side base, while SCOPEMA offers a driver-side Transit option. For other listings, check the stated orientation carefully; a left/right label or general compatibility claim may not settle fit for your exact setup.
What should I verify before ordering a pair of swivel bases?
Verify that the pair covers both intended seat sides and matches your Transit configuration and mounting holes. The Weonefit listing identifies an FTP004/FTP003 left-and-right pair, but the editorial guidance is to check the hole pattern and each base’s orientation before installation. Confirm the included hardware and instructions as well.
Final Words
For a clearly identified passenger-side Transit conversion, start with the Vahaha FTP004: its listing names Transit 150, 250, and 350, specifies FTP004, and includes mounting hardware. Choose SCOPEMA when you need an explicitly identified driver-side base; consider Weonefit for both front seats, after verifying each base’s orientation and hole pattern. Whichever option you compare, confirm your vehicle configuration, seat side, and mounting holes before ordering.
