Bought two soft pads, one was DOA. The other was dead after a few months. The hard ones basically don't exist as they cost too much to ship. Some entreprising industrial designer needs to do a good flat-pack one reconfigurable, ideally with nesting during shipping for higher density, and with multiple levels of upgrades. It would probably make bank on crowdfunding. Maybe on the ultra-budget version, you just buy the shell and slide in a soft pad.
