I've got a Nogaro in my BRZ. I absolutely love it, its the most comfortable car seat I've ever sat in. Its got really good support, and you can have them fitted with a heating element and lumbar support. Quite a few friends have them, and they have a similar opinion to myself.
Only minor issue is the standard seat belt, ideally I need a strap on the shoulder of the seat (like the factory seats have), to get the seat belt in a more comfortable position.
The seat is much better than an OE seat, it surpised me how much flex is in a OE (Gen 1) seat, a fixed bucket elimates all the seat flex.
Also being a Cobra seat, they can customise them to however you want.
If you want to try it, I'd happily meet up with you to try the seat out or I can ask my friend who lives in London, who also has a set in his Gen 1. I will say this though, I've driven his car twice and his seating angle is wrong for me personally, so I don't find his setup nearly as comfortable as mine.
Here are some pictures of mine:





Here's a couple of other photos from a Cars & Coffee at Cobra Seats, where they had a couple of Nogaro's on display:


I really want the red Ebisu edition seat, its lovely.
