CTA is our preferred swivel for camper vans. The same swivel works on both the driver and passenger seat, lock into place securely and swivel around with minimal adjustment of the seat position!

These CTA swivels sandwich a special aerospace phenolic self lubricating nylon disk wear plate thereby making the swivel virtually maintenance free and absent of rattles or vibration often found with ball bearing roller designs requiring periodic replacement. These are the #1 selling seat swivels used by the majority of OEM European camper manufacturers.

Each swivel includes detailed installation instructions and normally takes about 30-45 minutes to install.  First  you remove the seat from it’s factory “base” and then install this swivel adapter on top. Finally, you put the seat back on top of the swivel to complete the installation. The swivel adapter will raise the overall seat height by 1.65 inches.
