This is one of our most popular seats - and no surprise at this price.
We find this seat fits "Mr average" - it fits average sized competitors and is still supportive for a number of smaller competitors due to its deep sides.
As you would expect, the seat is side-mounted.
Our only watch-outs with this seat - it is wide across the shoulders so may struggle to fit in some cars. If you want to try it in your own car, we do have one available for fitment (One we use in our own car)
For a narrower seat - try the Champ R.
