Home theater seating is widely available and there is an extensive lineup of options which can give you exactly what you are looking for.
Something to be aware of is that proper home theater seating is fully modular. That is, you can get it in a 4-seat setup as a long couch, or as a loveseat in the center with two recliners on the ends, or a ton of other variations. You order it with the exact setup you would like and are not limited to a few small selections, but a wide variety in a long list of colors.
There are many custom home theater websites out there. Check some of them out. For example:https://4seating.com/home-theater-seating.htm
I don't support this site specifically, but I've looked through it in the past. It's a good example of what you can purchase and gives you some baseline budgetary considerations. It looks like it may be about $1,000 per seat for a quality product.
