Wanna put rear seat for Honda Cr-z any suggestion?

I live in USA, they only have two seater. The rear is not seat but cargo storage unit. But in other country such as Asia and Europe they have 4 seaters in Cr-z. I'm gonna removed cargo storage to put seat in rear. I'm gonna buy it online from foreign Honda parts website then have it ship to USA. So my two little children can sit behind me in my Cr-z.

Question is what's like after I removed cargo to install seat with seatbelts? More room? More comfortable for children. I mean they do sit in back before but sit on hard plastic which uncomfortable for long journeys.

Or maybe it's best to leave the way it is and let children sit on hard plastic if you're saying won't make any better when put in regular seats in just like Cr-z in Europe.

Wrong category.
