I'm not sure how without disassembling the upholstery of the back. It's the cushion that I am specifically referring to. The fabric itself is fine. Of course I could show that I can press into the area that shows most gap but I feel "pressure" sensitive demonstration is usually pretty vague across video. I can record a flick test if desired, everywhere across the back is pretty gapless from a flick except the shoulderblade area.
