Yup, it does indeed work fine if you have a drivers seat with armrests built-in. The double swivel has sufficient movement sideways to avoid your armrests.

If you want to swivel the drivers seat (with armrests) too then all you have to know is that you must spin the passengers seat half way around first, then rotate the drivers seat, and finally finish off the passengers seat. 

Easy !!

The driver offset swivel by RIB is too tight a fit and so does not work with our double seat swivel. You are best to go for a non-offset RIB swivel as this leaves a little more room for the double seat.
