I'm skeptical that a PCB is less strong than a breadboard. Have you tested this? If you use an SMT button you can always add a reinforcing layer of plastic under the PCB. If anything, surely it would be more comfortable to sit on a low profile button? Or some kind of strain sensor pad.

I've tested numerous methods over past two years; But the simplicity, reliability, structural integrity and cost of 170 point breadboard is hard to beat as its an inch thick(built like a lego).

I even tested with velostat fabric, but the resistance varies a lot and so there are numerous false triggers or missed triggers since we don't sit still on a chair.

No matter what's the thickness of the setup is, Any solid material under the butt is uncomfortable and so we need butt cushion for the setup. But with butt cushion, SMT button doesn't function as there's not enough travel, So we need a momentary button with button cap for enough surface area and travel to push into the cushion when we get up.
