Universal Campervan Seat Swivel Turntable Base for Motorhome Vans

Turn a fixed front seat into a more useful part of your campervan space. This universal swivel turntable gives you a practical way to rotate your seat and make better use of the room you already have.

It is built for van and motorhome conversions where flexibility matters. The wider, thicker design creates a sturdier fit, while the 90 degree locking positions keep the seat set where you want it.

This swivel base measures 36cm x 39cm with a height of 40mm. It is made from powdercoated steel and includes space for the seat to rotate. Once installed correctly, it gives your campervan or motorhome a more flexible layout without changing the seat itself.

Because it is a universal swivel base, installation is not straight out of the box for every van. Depending on your seat screw position, fitting can require re-drilling, welding, or adding a steel plate transition plate. That makes it better suited to experienced installers who want a universal part they can adapt to their build.

This base is not suitable for double bench seats. The detailed dimensions and hole position diagram make it easier to measure your seat base and plan the fit before any modification starts, which gives you more confidence during your conversion.

Compared with generic one-size parts, this design gives you more useful fitment information and a thicker, wider base that suits custom van projects where alignment and stability matter.
