I don't like leather furniture, so no worries there. I think the room is the biggest element in sound reproduction. As a non-audiophile, but music lover I also disagree with the method of more power or pricier gear equals overcoming room issues. All it that does is make things worse. One can take a pair of $100k speakers from a good room and put them in a different room and they will sound completely different (often times no good due to the room). The opposite is true as well, one can take a $400 pair of speakers and in a good room they will keep up with the best.
I believe in room treatments, but done correctly, that is very important. I've read (and seen pics) about so many people just either throwing corrections into a room willy nilly or filling the room with them and then wonder why the sound is still screwed up or worse. I think a little goes a long way with room corrections. I believe in speaker placement first and then testing the room with your ears (testing equipment can be helpful as well, but there is a steep learning curve and I have not learned it myself and I don't think many have) and then making use of items already on hand if one can before plunking down money on corrections. Purpose built corrections if needed, need to be placed carefully or efficiently/effectively in a room. Slowly adding corrections is the best route in my opinion. Start with one issue or correction and you can always add later if needed. If items on hand don't do it then I think often times one will find that usually 1 to 4 pieces of purpose built room correction is all that will be needed in lots of cases unless your trying to build a recording studio or anabolic chamber or trying to treat an impossible room in which case your wasting time and money. (My current room is a good example of that).
Just my 1 cent.
