Had the van converted when i bought it. The swivel is terrible, rocks like mad when you sit on it and really hard to turn. It’s cuffing the pillar terribly, no matter how gently I try. I even bought a Kiravans single swivel for the drivers. So my query really is, do i go down the route of a single, or are their ones which rotate without catching the pillar. Happy to pay for a single and get more seat covers, but need to get it right this time. If i go down the route of a single, does it just bolt in to the same holes.
