Cj the newbie

Is there an online shop you know of that can do it? Only ask here because I'll take it as a couch for them

Do you mean just fitting them perfectly in a box, or is there more to it?

Well I would love to have a very reputable brand, the problem is I don't know which ones those are..budget isn't very limited, don't want to purchase the most expensive available but would definitely want to buy really good equipment. Do it right the first time is my opinion. And what do you mean by optimizing the box? Like I said I'm blind haha.
