Query: NOT FIRM - Misleading Illustration

The illustration shows how a person is being uplifted with this cushion - If someone of 170lbs weight sits in it - this sinks and it becomes useless - My solution of using a sofa cushion was better because it was more firm and I didn't have to buy another thing. I figured this would be more compact, neat and firm - so if you need tailbone relief there maybe some purpose - else - its useless.
