I am happy with my Lovesac sofa, too. It was expensive, but I can't think of another product I could expect to be as happy with, so Lovesac seems to be in a class of their own and can demand whatever price they want.
In particular, it's comfortable, well built, but not bulky. I can take it apart move it in my regular sized SUV if needed. I move a lot, and eventually grew tired of bulky things that were difficult or impossible to move without professional help.
I also tried a Burrow sofa which has the same modular properties, but it was not comfortable at all and I had to return it
I got one for just $700 over MSRP in Pasadena recently. Had to visit multiple dealerships and haggle them down quite a bit (They wanted $5000 over). Although not easy, it's possible now, they aren't as unobtainable as they once were.
