We much prefer our MS Craft swivel, compared to the Kiravans swivel that was fitted when we bought the van.

The Kiravans swivel was well made but you had to swivel the seat in position, which was tricky. The MS Craft swivel slides the seat backwards, which makes it easier to swivel. You can also sit on it at an angle when it is slid back, as above. I am glad I switched it.
