@twhitezzz I bought 3 large rugs and placed one each on the the back and front walls and the 3rd on the floor in front of my speakers (the rug reaches a foot behind my listening area). I had 4 Aurelex Geofusors and placed 2 (stacked) about 3 feet behind each speaker. That's it. My music is meaty, spacious and voices and instruments are focused. I hear music to the sides of and behind my speakers (depending on the recording). The bass is tight and authoritative. I just ordered a reclining barber's chair with a small headrest as my listening chair. My house is 9 years old so the walls are cement blocks with rolls of fiberglass insulation between studs. I initially tried using absorbers to the sides of the speakers, but they sucked up the mid frequency so I removed them. I only have corners on the left side. The right side is to open space. Now all I need to do is make sure my sump pump is working at peak performance :) Those Yogibo bean bags sound interesting.
@mike_in_nc sounds like all your investment and effort has reaped great benefits!
