The Single Swivel Base is a slim 43mm plate that adds 360° rotation only — choose it when headroom or seat height matters most. The Swivel Base with Slider Rails is 100mm tall and adds integrated fore-aft slider rails plus four 90° locking positions, so you can both rotate the seat and slide it forward or back. Both use a handle-operated release.
The Single Swivel Base adds about 43mm (1.7in) and the Swivel Base with Slider Rails about 100mm (3.9in). Measure your headroom before ordering — in vans with low roofs or under-seat services, the slim version is usually the safer choice.
It's a universal design with slotted mounting holes that suit most RV, camper van, motorhome, minibus and commercial-vehicle seat conversions. Footprint is roughly 390 × 297mm (slim plate) and 390 × 295mm with 360mm slider rails. Because every vehicle's seat pedestal and bolt pattern differs, compare your seat frame and floor bolt pattern with these dimensions — some vehicles need adapter brackets, which are made vehicle-specific. Send us your make, model and year and we'll help you check.
No. The seat must be locked in the forward-facing position whenever the vehicle is moving. Only rotate the seat when the vehicle is parked with the handbrake applied. Always confirm the base is fully locked into its detent before setting off.
We strongly recommend professional installation. This part replaces a structural seat mounting, and seat mounts carry crash loads and are often tied to seatbelt anchorages and airbag or seat-occupancy wiring. A qualified installer or vehicle converter will confirm bolt grades, torque values and bracket design for your vehicle. Expect roughly 2-4 hours.
It can. If your seatbelt anchor is mounted to the seat frame, rather than the B-pillar or floor, adding a swivel changes the load path and needs professional assessment. Many seats also carry airbag or occupancy sensor wiring that must be routed so it can't be pinched or stretched by rotation. Rules on modifying seat mountings vary by country and can affect roadworthiness inspections and insurance — check your local regulations before fitting.
No — the base uses thickened steel with reinforced ribbing and a positive locking mechanism designed for a solid, wobble-free and squeak-free seat while driving. Re-check bolt torque after the first few hundred kilometres, as with any seat hardware.
In outline: disconnect the battery and wait before starting, so any airbag system is safely powered down; unbolt and remove the factory seat, carefully unplugging any seat wiring; mount the swivel base to the floor or seat pedestal using the correct bolts and torque; mount the seat onto the swivel base; reconnect wiring, refit and test that the base locks firmly in every position before use. Full steps are in the installation guide on this page — and again, we recommend a professional installer.
