in my experience when it comes to sofas the old "buy cheap buy twice" holds true. there are reputable brands such as ligne roset for example. they are pricey bit if you can commit to buying and owning for > 15 years. owning a clam and a togo for more than ten years and the are basically like new. foam & fabric. i understand this might unaffordable to a lot of people but buying second hand can be a great deal on high end sofas.
