It's been said many times that, "If you can dream it, H&M can build it." OK, but what I want to know is, what kinds of customizations can be done for a modest cost? Of course "modest" is subjective, so I'm just looking for generalizations. So for the sake of argument, let's say that "modest" is somewhere around the same cost as going up one leather grade. Ish. Give or take.

For example: Could I put different legs on it? Could I get it without the castors that are shown in the picture? What about adding or subtracting quilting or tufting? What if it's just on one cushion? How about adding a gimp? There must be lots that I haven't thought of, too.
